Abstract

A method and system for acquiring a series of medical images during a common imaging process, includes a plurality of detectors configured to be arranged to acquire gamma rays emitted from a subject as a result of multiple radiotracers administered to the subject and communicate signals corresponding to acquired gamma rays. A data processing system is configured to receive the signals from the plurality of detectors and identify temporal information and energy information of photons of the acquired gamma rays. A reconstruction system is configured to receive the signals, the temporal information, and the energy information from the data processing system and reconstruct therefrom a series of medical images of the subject, wherein at least one of the images in the series of medical images corresponds to only to information acquired from gamma rays emitted as a result of a given one of the multiple radiotracers.
