Quantitative PET and SPECT performance characteristics of the Albira Trimodal pre-clinical tomograph
Publikováno v:
Physics in Medicine and Biology. 59:715-731
The Albira Trimodal pre-clinical scanner comprises PET, SPECT and CT sub-systems and thus provides a range of pre-clinical imaging options. The PET component consists of three rings of single-crystal LYSO detectors with axial/transverse fields-of-vie

The EXACT 3D PET scanner uses a Cs-137 single photon rotating point source for the transmission scan. As the source is un-collimated, the transmission data are contaminated by scatter. It has been suggested that segmentation of the reconstructed imag

Movement degrades image quality in PET/CT. Two types of motion can be described: respiratory and global body motion, also called patient motion. In this study, an analysis of both types of movement is carried out in the context of dynamic PET acquisi

In this work, we introduce a new scatter simulation algorithm where the probability of having double scatter occurrences is calculated by the polarized Klein-Nishina formula. During the evaluation, we illustrate when the use of the polarized Klein-Ni

The measurement of regional myocardial blood flow (MBF) with (H2O)-O-15 and PET requires an additional (CO)-O-15 blood-pool scan for the purpose of region of interest (ROI) definition. This additional scan results in a substantially increased radiati
