Abstract:
A method for use with a medical imaging system and a tracer substance, the tracer substance positioned within an organ to be imaged which is positioned within an imaging area, the substance generating sub-atomic particles which emanate therefrom, the system including at least one camera and a processor, the camera including a plurality of adjacent detector sets and positioned adjacent the imaging area, each detector set including a plurality of adjacent detectors, each detector detecting emanating particles and providing a pulse to the processor for each particle detected, the method for, during an acquisition period that comprises sub-periods, generating at least one high resolution data acquisition and, during each sub-period, generating a unique low resolution data acquisition, the method comprising the steps of:during each sub-period, for each detector subset, counting the pulses generated by the subset detectors and storing the subset pulse counts as the low resolution acquisition data set associated with the sub-period; andduring a high resolution period, for each detector, counting all of the pulses generated by the detector and storing the detector pulse counts as the high resolution acquisition data set.
