Image Reconstruction in Dynamic PET Imaging & Regularisation Methods for Joint Image Reconstruction.
Abstract: Dynamic positron emission tomography (PET) imaging captures temporal information of biological processes in living tissue. This technique can be used, for example, for diagnosis and treatment monitoring of cancers and brain diseases by studying the activity distribution of radioactively-labelled pharmaceuticals injected into the patient’s body. Reconstructing time-varying images from a set of physical measurements (photon counts) is challenging due to the low signal-to-noise ratio and low spatial resolution of standard PET scanners. In this talk we present a reconstruction method...Read More
