Objective:<br/>This pilot study aims to assess the environmental impact of Positron Emission Tomography/Computed Tomography (PET/CT) imaging, in the context of efforts to mitigate climate change. This is studied by investigating the energy usage, waste generation, and the radiopharmaceutical production.<br/><br/>Methods:<br/>Power measurements...

This thesis aimed to validate Beekman's patent on how collimation could virtually reduce the focal spot size of an existing small-animal cone beam Computed Tomography (CT) system to diminish the penumbra effect. The ever-remaining drive to improve the spatial resolution in CT for enhanced image quality introduces the need for small focal spot...

With multi-pinhole collimation systems, high resolutions can be reached with both SPECT and PET. Using tracers with higher-energy gamma-photons increases the effects of pinhole edge penetration, decreasing the resolution of the system. This research aims to design a collimator using 3x3 twisted pinhole clusters to be used in the VECTor system....
