  @article{Hetzel_2023, abstract = {Objective. Prompt-gamma imaging encompasses several approaches to the online monitoring of the beam range or deposited dose distribution in proton therapy. We test one of the imaging techniques - a coded mask approach - both experimentally and via simulations. Approach. Two imaging setups have been investigated experimentally. Each of them comprised a structured tungsten collimator in the form of a modified uniformly redundant array mask and a LYSO:Ce scintillation detector of fine granularity. The setups differed in detector dimensions and operation mode (1D or 2D imaging). A series of measurements with radioactive sources have been conducted, testing the performance of the setups for near-field gamma imaging. Additionally, Monte Carlo simulations of a larger setup of the same type were conducted, investigating its performance with a realistic gamma source distribution occurring during proton therapy. Main results. The images of point-like sources reconstructed from two small-scale prototypes’ data using the maximum-likelihood expectation maximisation algorithm constitute the experimental proof of principle for the near-field coded-mask imaging modality, both in the 1D and the 2D mode. Their precision allowed us to calibrate out certain systematic offsets appearing due to the limited alignment accuracy of setup elements. The simulation of the full-scale setup yielded a mean distal falloff retrieval precision of 0.72 mm in the studies for beam energy range 89.5–107.9 MeV and with 1 × 108 protons (a typical number for distal spots). The implemented algorithm of image reconstruction is relatively fast—a typical procedure needs several seconds. Significance. Coded-mask imaging appears a valid option for proton therapy monitoring. The results of simulations let us conclude that the proposed full-scale setup is competitive with the knife-edge-shaped and the multi-parallel slit cameras investigated by other groups.}, author = {Hetzel, Ronja and Urbanevych, Vitalii and Bolke, Andreas and Kasper, Jonas and Kercz, Monika and Kołodziej, Magdalena and Magiera, Andrzej and Mueller, Florian and Müller, Sara and Rafecas, Magdalena and Rusiecka, Katarzyna and Schug, David and Schulz, Volkmar and Stahl, Achim and Weissler, Bjoern and Wong, Ming-Liang and Wrońska, Aleksandra}, journal = {Physics in Medicine & Biology}, keywords = {nuci}, month = 12, number = 24, pages = 245028, publisher = {IOP Publishing}, title = {Near-field coded-mask technique and its potential for proton therapy monitoring}, volume = 68, year = 2023 }

Workflow 1 is designed to model the response of the Biograph Vision Quadra as closely as possible by using a custom readout and digitizer modeling tool with an integrated coincidence sorter. Further, the same image reconstruction is performed as for real scan data with the e7 tools (Siemens Healthineers). Workflow 2 is developed for increased flexibility based on open-source software and the Customizable and Advanced Software for Tomographic Reconstruction (CASToR) code for image reconstruction. Phantom simulation studies were performed to validate the workflows against measurement data. Using the normalization matrix of the real scanner with an adapted calibration factor, Workflow 1 demonstrated an excellent quantification accuracy with differences of less than 1% for three different phantoms. Image quality analysis using an IEC phantom simulation with 60 s scan time showed good agreements of contrast recovery coefficients and lung residual error with experimental data. The anthropomorphic XCAT phantom was used for patient-like simulations. The successful NEMA-NU validation of the simulation workflows will enable the investigation of scenarios which practically cannot be tested on patients.

These phantoms can be rods, flat sources, or cylinders that consist of cavities that are filled with liquid radioisotopes. The use of such phantoms is a well-established standard. With the advent of 3D printing, a promising alternative approach is to print solid radioactive phantoms. The literature shows that it is possible to manufacture solid calibration phantoms with short-lived radioisotopes. On the way to printing long-lived radioactive objects, we tested the method using 18F-FDG to construct very small phantoms with submillimeter structures for future use in small-fish PET. A commercial printer was modified for this purpose. We were able to print different phantom shapes and structures with homogeneous activity distributions as well as phantoms with hot, cold and background regions. The use of hollow phantoms of the same size, to be filled with activity, is not considered a practical alternative due to their small size. In addition, air bubbles that occur during filling can also reduce the quality.}, author = {Elmoujarkach, Ezzat and Seeger, Steven and Möller, Nadine and Schmidt, Christian and Rafecas, Magdalena}, booktitle = {2022 IEEE Nuclear Science Symposium and Medical Imaging Conference (NSS/MIC)}, keywords = {ki-inspire}, month = 11, pages = {1-2}, title = {Development and Characterization of 3D Printed Radioactive Phantoms for High Resolution PET}, year = 2022 }

We introduce a new treatment verification technique to estimate the primary particle's stopping power from prompt gamma timing measurements in proton therapy. Approach. The starting point is the Spatio-temporal Emission Recostruction technique, which provides the time-depth distribution of the emitted prompt photons with a multiple Prompt-Gamma Timing detector setup based on Lanthanum Bromide crystals. A dedicated formalism based on an analytical approximation of the stopping power is developed to obtain the desired information. Its performance is evaluated in a proof of concept configuration via Monte Carlo simulations of monochromatic proton beams impinging on a homogeneous PMMA phantom. Main Results. Results indicate stopping power estimations as good as 3.8% with respect to NIST values, and range estimations within 0.3 cm (standard deviation), when considering 250 ps FWHM timing resolution.

State of the art MPS devices are solely capable of measuring the magnetization response of the SPIONs to an oscillatory magnetic excitation retrospectively, i.e. after the synthesis process. In this contribution, a novel in-situ magnetic particle spectrometer (INSPECT) is presented, which can be used to monitor the entire synthesis process from particle genesis via growth to the stable colloidal suspension of the nanoparticles in real time. The device is suitable for the use in a biochemistry environment. It has a chamber size of 72 mm such that a 100 ml reaction flask can be used for synthesis. For an alkaline-based precipitation, the change of magnetic properties of SPIONs during the nucleation and growth phase of the synthesis is demonstrated. The device is able to record the changes in the amplitude and phase spectra, and, in turn, the hysteresis. Hence, it is a powerful tool for an in-depth understanding of the nanoparticle formation dynamics during the synthesis process.}, author = {Malhotra, Ankit and von Gladiss, Anselm and Behrends, André and Friedrich, Thomas and Neumann, Alexander and Buzug, Thorsten M. and Lüdtke-Buzug, Kerstin}, journal = {Scientific Reports}, keywords = {luedtkekerstin}, month = {07}, number = 10538, title = {Tracking the Growth of Superparamagnetic Nanoparticles with an In-Situ Magnetic Particle Spectrometer (INSPECT)}, volume = 9, year = 2019 }

  @article{8845670, abstract = {In-beam PET monitoring can provide early treatment assessment in proton therapy. However, open ring configurations and low positron emitter production yields degrade image quality, hampering the assessment accuracy. To achieve the highest precision for range monitoring, it is compulsory to mitigate image noise and compensate for data truncation. The goal of this work is to study the performance of state-of-the-art algorithms for in-beam PET image reconstruction, by evaluating the impact of the system response model and assessing the accuracy of range measurements. The approaches investigated here were Maximum-A-Posteriori algorithms combined with Total-Variation and Median-Root Priors. Maximum-Likelihood-Expectation-Maximization was used as reference. To compute the system matrix, different models were compared: a precise Monte Carlo model, and Single-Ray Tracing with and without Gaussian blurring in image space. The proposed methods were tested on simulations of Spread-Out-Bragg-Peaks delivered on phantoms. The I3PET scanner geometry was used as a case study. After image post-processing, the explored methods delivered similar results. Our work demonstrates the feasibility and reliability of using a simple and fast reconstruction method to perform range evaluations, given the correct image post-processing.}, author = {{Ferrero}, V. and {Pennazio}, F. and {Cerello}, P. and {Fiorina}, E. and {Garbolino}, S. and {Monaco}, V. and {Wheadon}, R. and {Rafecas}, M.}, journal = {IEEE Transactions on Radiation and Plasma Medical Sciences}, keywords = {imt}, title = {Evaluation of in-beam PET treatment verification in proton therapy with different reconstruction methods}, year = 2019 }

  @article{0031-9155-61-12-4583, abstract = {The imaging technology magnetic particle imaging allows the detection of magnetic material, in particular superparamagnetic nanoparticles, by remagnetization of the material via magnetic fields. The application is aimed at medical imaging where the particles are applied as tracer directly into the blood stream. Medical safety considerations such as peripheral nerve stimulation limit the maximal amplitude of the magnetic fields and in turn the field of view size. To handle this constraint the concept of patches was introduced, which allows a shift of a field of view to different positions in order to enlarge the imaging area. If this is done statically an overlap of patches can be used to reduce truncation artifacts occurring at the adjacent edges. In this contribution, a differentiation of two different kinds of patch overlaps, i.e. a trajectory and a system matrix overlap, is made. Further, different concepts to combine the resulting redundant information are investigated with respect to the reduction of truncation artifacts. The methods are analyzed in detail in a simulation study and validated on experimental data.}, author = {Ahlborg, M and Kaethner, C and Knopp, T and Szwargulski, P and Buzug, T M}, journal = {Physics in Medicine and Biology}, keywords = {buzugthorsten}, number = 12, pages = 4583, title = {Using data redundancy gained by patch overlaps to reduce truncation artifacts in magnetic particle imaging}, volume = 61, year = 2016 }

When using drive fields to achieve the FFP movement, a fast spatial encoding of the FOV is enabled. Due to safety limits, in terms of patient heating and nerve stimulation, the amplitude of the applied currents needs to be small, which results in a small FOV. In order to enlarge the FOV, focus fields featuring a high amplitude and a low frequency can be used. In this contribution, an approach based on a linear focus field shift, which enlarges the FOV in axial direction, is proposed. Such a shift results in an elongation of a planar two-dimensional trajectory that features a controlled sub-sampling of the FOV.I Results show that a focus field based trajectory elongation in axial direction is a suitable data acquisition for MPI. In addition to this, the use of self-intersection points as trajectory specific axial distance measure has been proposed.}, author = {Kaethner, C. and Ahlborg, M. and Buzug, T.M.}, booktitle = {International Workshop on Magnetic Particle Imaging}, keywords = {AhlborgMandy}, month = {03}, title = {Focus field based trajectory elongation in MPI}, year = 2015 }

  @article{Bente2014a, abstract = {It has been shown that magnetic particle imaging (MPI), an imaging method suggested in 2005, is capable of measuring the spatial distribution of magnetic nanoparticles. Since the particles can be administered as biocompatible suspensions, this method promises to perform well as a tracer-based medical imaging technique. It is capable of generating real-time images, which will be useful in interventional procedures, without utilizing any harmful radiation. To obtain a signal from the administered superparamagnetic iron oxide (SPIO) particles, a sinusoidal changing external homogeneous magnetic field is applied. To achieve spatial encoding, a gradient field is superimposed. Conventional MPI works with a spatial encoding field that features a field free point (FFP). To increase sensitivity, an improved spatial encoding field, featuring a field free line (FFL) can be used. Previous FFL scanners, featuring a 1-D excitation, could demonstrate the feasibility of the FFL-based MPI imaging process. In this work, an FFL-based MPI scanner is presented that features a 2-D excitation field and, for the first time, an electronic rotation of the spatial encoding field. Furthermore, the role of relaxation effects in MPI is starting to move to the center of interest. Nevertheless, no reconstruction schemes presented thus far include a dynamical particle model for image reconstruction. A first application of a model that accounts for relaxation effects in the reconstruction of MPI images is presented here in the form of a simplified, but well performing strategy for signal deconvolution. The results demonstrate the high impact of relaxation deconvolution on the MPI imaging process.}, author = {Bente, K. and Weber, M. and Graeser, M. and Sattel, T. F. and Erbe, M. and Buzug, T.

Their homogeneity decreases with higher radius, which is both shown in Fig. 4. Arrays of circular coils show very good homogeneity, which further increases with increasing number of coils, but have comparably poor sensitivity in the FOV. D-shaped coils have both decreasing sensitivity and homogeneity with increasing radius. An increasing distance between a D-coil pair increases the homogeneity, but leads to decreasing sensitivity. Nested D-coils can show an improved homogeneity without a loss in sensitivity. Optimized circular and not nested D-shaped coil pairs with a radius of 15 cm were manufactured and the resonance frequency for both geometries was measured to be about 1.9 MHz for the tight and 2.6 MHz for the loose winding technique.}, author = {Tenner, W. and Wojtczyk, H. and Bringout, G. and Graeser, M. and Grüttner, M. and Haegele, J. and Duschka, R.L. and Panagiotopoulos, N. and Vogt, F.M. and Barkhausen, J. and Buzug, T.M.}, booktitle = {International Workshop on Magnetic Particle Imaging}, keywords = {BringoutGael}, month = {03}, title = {Receive coil optimization for an open magnetic particle imaging scanner}, year = 2013 }

  @article{Kratz2012b, abstract = {Purpose: In computed tomographyimaging metal objects in the region of interest introduce inconsistencies during data acquisition. Reconstructing these data leads to an image in spatial domain including star-shaped or stripe-like artifacts. In order to enhance the quality of the resulting image the influence of the metal objects can be reduced. Here, a metal artifact reduction (MAR) approach is proposed that is based on a recomputation of the inconsistent projection data using a fully three-dimensional Fourier-based interpolation. The success of the projection space restoration depends sensitively on a sensible continuation of neighboring structures into the recomputed area. Fortunately, structural information of the entire data is inherently included in the Fourier space of the data. This can be used for a reasonable recomputation of the inconsistent projection data. Methods: The key step of the proposed MAR strategy is the recomputation of the inconsistent projection data based on an interpolation using nonequispaced fast Fourier transforms (NFFT). The NFFT interpolation can be applied in arbitrary dimension. The approach overcomes the problem of adequate neighborhood definitions on irregular grids, since this is inherently given through the usage of higher dimensional Fourier transforms. Here, applications up to the third interpolation dimension are presented and validated. Furthermore, prior knowledge may be included by an appropriate damping of the transform during the interpolation step. This MAR method is applicable on each angular view of a detector row, on two-dimensional projection data as well as on three-dimensional projection data, e.g., a set of sequential acquisitions at different spatial positions, projection data of a spiral acquisition, or cone-beam projection data. Results: Results of the novel MAR scheme based on one-, two-, and three-dimensional NFFT interpolations are presented. All results are compared in projection data space and spatial domain with the well-known one-dimensional linear interpolation strategy. Conclusions: In conclusion, it is recommended to include as much spatial information into the recomputation step as possible. This is realized by increasing the dimension of the NFFT. The resulting image quality can be enhanced considerably.}, author = {Kratz, Bärbel and Weyers, Imke and Buzug, Thorsten M.}, journal = {Medical Physics}, keywords = {MetalArtefactReduction}, number = 11, pages = {7042-7054}, title = {A fully 3D approach for metal artifact reduction in computed tomography}, volume = 39, year = 2012 }

The spatial distribution of these particles can be determined by solving a system of linear equations.

This paper introduces a new approach combining both possibilities. A Magnetic Particle Spectrometer is used to obtain a hybrid system function. Furthermore, we will show that the hybrid system function can be successfully used for 1D-image reconstruction and potentially is an alternative to the measurement-based system function.}, author = {Grüttner, M. and Graeser, M. and Biederer, S. and Sattel, T.F. and Wojtczyk, H. and Tenner, W. and Knopp, T. and Gleich, B. and Borgert, J. and Buzug, T.M.}, booktitle = {Nuclear Science Symposium and Medical Imaging Conference}, keywords = {AhlborgMandy}, month = 10, pages = {2545-2548}, title = {1D-image reconstruction for magnetic particle imaging using a hybrid system function}, year = 2011 }

  @inproceedings{Ens:2010c, abstract = {Motion correction is an important task in computed tomography. Small movements lead to a reduced resolution of the reconstructed images; strong movements may lead to a false diagnosis. Thus, motion detection and subsequent correction are necessary. In this work, we propose an algorithm for the automatic estimation of movement positions and motion correction by the simultaneous estimation of motion parameters and the determination of the corrected reconstruction. Distance metric values, computed from two successive projection images, provide information of the incorporation of movement. Reconstruction correction is achieved by minimization of an image quality function. Two no-reference image metrics show sufficient correlation with the amount of motion artifacts: entropy and bandpass-metric. The aim of the optimization method is to find a pair of image and motion parameters by minimization of the metric. However, the described method for the estimation of movement positions can also be used as a pre-processing step of the data-driven motion-correction (DDMC), a recently published motion correction method, for subdivision of the projection data into motion free subsections. Since the proposed method uses the Feldkamp algorithm (FDK) for reconstruction, we expect a shorter computation time then for the iterative reconstruction based DDMC. The proposed method works solely on information contained in cone-beam projections.}, author = {Ens, S. and Ulrici, J. and Hell, E. and Buzug, T.M.}, booktitle = {Nuclear Science Symposium and Medical Image Conference}, keywords = {IMT}, month = 10, pages = {3248-3251}, title = {Automatic motion correction in cone-beam computed tomography}, year = 2010 }

On the other hand, the continuously growing computational power of today's standard computers has led to a rediscovery of these methods. Currently, filtered backprojection (FBP) is the reconstruction method of choice, because it is very fast, especially on dedicated hardware. However, a disadvantage of FBP is that it ignores some of the physical effects like beam hardening, scatter and noise, leading to artifacts in the reconstructed images. Artifacts of this type are particularly dominant if metal objects are inside the patient, because FBP interprets the corresponding projection data as inconsistent. For the method proposed here, the inconsistency of the metal-influenced projection data is reduced with an interpolation scheme working in the Radon-space domain. As the interpolation yields a vague estimate of the real soft-tissue projection values, residual inconsistencies remain. Those residuals can be treated by a modified maximum likelihood expectation maximization (MLEM) method presented in this paper. Within the novel approach, different projection lines through the object can be associated with appropriate weightings that decrease the influence of the residual inconsistencies - resulting in an overall image-quality enhancement. The approach is demonstrated on real CT measurements of a torso phantom equipped with metal markers that allows an evaluation with the corresponding ground truth data.}, author = {Oehler, M. and Buzug, T.M.}, booktitle = {Nuclear Science Symposium and Medical Imaging Conference}, keywords = {MetalArtefactReduction}, month = 10, pages = {3511-3518}, title = {Modified MLEM Algorithm for Artifact Suppression in CT}, volume = 6, year = 2006 }
