Abstract: A method for performing a partial scan of a patient using a PET/CT system includes receiving a selection of a region of interest for scanning and performing a CT scan over a region of interest with the PET/CT system to acquire raw CT data. The raw CT data is reconstructed into one or more CT images. The PET/CT system is configured to limit data collection to the region of interest. A PET scan limited to a region of interest is performed with the PET/CT system to acquire raw PET data. The raw PET data is reconstructed into one or more PET images of the region of interest.

Abstract: An apparatus for manufacturing a radioisotope comprises a container. The container comprising a portable neutron source and a solution that comprises a particular isotope. The portable neutron source is surrounded by the solution. The solution comprises at least one of copper phthalocyanine or copper salicylaldehyde o-phenylene diamine. The portable neutron source emits neutrons that react with the particular isotope resulting in the transformation of the particular isotope into the radioisotope.

Abstract: A medical imaging and/or radiotherapy apparatus incorporates a display for projecting a visible image to a patient lying on a patient table. A projector that projects the visible image moves in tandem with the patient table, so that it appears relatively motionless to the patient. In exemplary embodiments, the projector projects the visible image within a patient tunnel of the medical apparatus, including in some embodiments, an extended field of view medical imaging apparatus. In other exemplary embodiments, the projector projects the visible image on a screen above the patient table of a tunnel-less medical apparatus. The projector remains outside the imaging line of response of detectors within the imaging field or outside of the radiotherapy beam zone, to avoid potential degradation of the captured diagnostic image or degradation of the radiotherapy beam.
