Coupling target and radioactive emitter matters: a sub-tissue dosimetric study to identify optimal strategies

Abstract Background Radiopharmaceutical-therapy dosimetry depends on both radionuclide emission physics and the spatial distribution of activity. We evaluated how radionuclide identity and protein-defined subcellular localization influenced cancer-cell nuclear absorbed-dose distr...

Artificial Intelligence Across the PET Reconstruction Pipeline: An Update

PET reconstruction has evolved from analytic and iterative physics-based methods toward hybrid approaches that increasingly incorporate artificial intelligence (AI). As digital detectors, long-axial FOV systems, and time-of-flight technology increase data richness and computation...
