@inproceedings{10399242, abstract = {Nuclear imaging techniques such as Positron Emission Tomography (PET) and Single-Photon Emission Computed Tomography (SPECT) use radioactive phantoms for calibration, quality assurance, and characterization. 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 }

The design is based on the combination of two existing prototypes and allows for a first investigation of the bi-modal acquisition of the radionuclides <sup>89</sup>Z<inf>r</inf> and <sup>124</sup>I. Since the simulation framework GATE is not able to properly output coincidences of such a bi-modal system, a post-processing tool was developed. This includes custom coincidence sorting and classification of PET and CC data. Here we present our postprocessing pipeline as well as our first results, and discuss the implications of the coincidence logic and the fraction of randoms on the data. The availability of such data is the prerequisite for developing novel image reconstruction approaches.}, author = {Bolke, A. and Zvolsky, M. and Kohlhase, N. and Seeger, S. and Schaar, M. and Rafecas, M.}, booktitle = {2020 {IEEE} Nuclear Science Symposium and Medical Imaging Conference ({NSS}/{MIC})}, keywords = {PET}, month = 10, pages = {1-3}, title = {Modelling of a Bi-Modal PET / Compton-Camera System for Non-Pure Positron Emitters}, year = 2020 }
