Abstract:
A method of nuclear imaging comprising:injecting a subject with a radiopharmaceutical; collimating radiation emitted by the radiopharmaceutical with parallel collimator vanes; applying a voltage bias to a two dimensional array of CZT crystals; converting the collimated radiation into electrical signals with the array of CZT detectors; processing the signals from the array of CZT detectors with electrical components mounted to a parallel array of spaced circuit boards and concurrently generating heat with the electrical components; disposing fans that move the air past the circuit boards adjacent a detector housing; moving air between the circuit boards removing the heat; rotating the collimator vanes, the detector array, and the circuit boards around the subject and an axis of rotation; as the collimator vanes, the detector array and the circuit boards rotate around the axis of rotation, moving the collimator vanes, the detector array and the circuit boards about an axis with lateral rotational components of motion relative to the axis of rotation; converting the processed signals into a human viewable image.
