Positron Emission Tomography (PET) is a functional medical imaging technique that allows for the visualization and measurement of metabolic processes in the body by detecting pairs of 511-keV gamma rays originating from a tracer molecule
labeled with a positron emitter.
Despite its advanced capabilities, PET imaging faces significant challenges, including high noise levels and limited spatial...
In Positron Emission Tomography the problem of image distortion due to scattered photons or accidental coincidences becomes more pronounced for large field-of-view scanners capable of measuring the whole patient in one scan. We propose a novel method of encoding coincidence event information to enhance the efficiency of noise filtration classification. The proposed encoding enables the usage...
Positron Emission Mammography (PEM) is a Nuclear Medicine technique for breast imaging based on a dedicated scanner assembled with parallel dual-panel detector arrays. Patient positioning in close contact with the scanner enhances spatial resolution and sensitivity in comparison with ring-based scanners, but this geometry hinders the adaptation of conventional attenuation and scatter...
