Abstract: The present disclosure relates to scintillating detector systems for radiation therapy beams. In one implementation, a detector system for evaluating radiation delivered by a radiation beam output from a beam generator may include a phantom enclosing an internal volume and having an outer surface, extending around the internal volume, for exposure to radiation, and an inner surface coated, at least in part, with a scintillating material and facing the internal volume. The system may further include a camera external to the enclosed volume and configured to view at least a portion of the inner surface, through an opening of the hollow phantom, when radiated by the radiation beam. The system may further include at least one processor configured to receive images from the camera and calculate, based on the received images, a spatial dose distribution produced by the radiation delivered by the radiation beam to the hollow phantom.
