FAST PHOTON COUNTING ASSAY SYSTEM AND METHOD

摘要

An automated system and method are disclosed for use in assaying radiation emitted by radiotherapeutic products such as brachytherapy seeds. The system and method include an enclosure containing a SCARA robot that is selectively positionable at a plurality of work stations, a calibration seed holder, a vibratory feeder, a radiation detector and an array of storage vials. Pulses from the radiation detector are directed to a fast coincidence counter and CPU, which computes the radiation dosimetry and signals the robot to deposit the assayed product in a particular storage vial within the array.
