Air cooled PET scanner gantry

A medical image scanner gantry comprising:

• cooling air delivery manifold comprising:
• a patient tunnel portion;
• and
• a front funnel portion;
• a plurality of gamma detectors housed inside the medical image scanner gantry and positioned behind the front funnel portion that comprises:
• an annular interior wall defining an entry opening of the patient tunnel portion;
• and
• an assembly of two or more air plenums, wherein each of the two or more air plenums has a curved structure that together form an annular assembly, wherein each of the two or more air plenums comprising a structure for carrying a flow of pressurized air received from a remote source, wherein each of the two or more air plenums comprising a curved nozzle configured for directing the flow of pressurized air toward the plurality of gamma detectors as a flow of high-velocity air for cooling the plurality of gamma detectors and their associated electronic components;
• wherein the annular interior wall is nested inside the annular assembly formed by the two or more air plenums, whereby a supplemental air inlet is formed between the annular interior wall and the two or more air plenums, whereby when the flow of high-velocity air flows out of the curved nozzles, ambient air is drawn through the supplemental air inlet and merges with the flow of high-velocity air exiting the curved nozzles and flows toward the plurality of gamma detectors as cooling air flow.
