In quantitative positron emission tomography (PET) brain studies, the temporal dynamics of the radiopharmaceutical are usually analyzed separately for different brain structures. In a clinical environment, the delineation of brain structures is still often performed manually by human experts. In this study, we concentrate on automatic segmentation of the striatal brain structures (caudate, posterior...
Certain neurological disorders such as Parkinson's disease are diagnosed by imaging centrally located brain structures such as basal ganglia and striatum. High sensitivity imaging of these structures is essential for the early-stage diagnosis of the disorder. We simulated a multi-geometric collimator that combines a short-focal-length astigmatic half-cone-beam collimator, designed to efficiently image...
