1. A radiation therapy system comprising:
a radiation source configured to direct one or more radiation pulses toward a PET-avid region of interest;
a plurality of PET detectors, wherein the plurality of PET detectors are configured to detect positron annihilation photons; and
a controller comprising a signal processor, wherein the controller is configured to gate a PET detector output signal from the plurality of PET detectors to the signal processor for a predetermined period of time following each radiation pulse, wherein the predetermined period of time is longer than a blanking interval of the plurality of PET detectors.
