摘要：
The disclosure is directed to an apparatus, system, and method for performing energy-resolved scatter imaging during radiation therapy upon a patient. The apparatus includes a radiation detector capable of resolving the energy of the scattered photons due to Compton scattering during radiation therapy. The radiation detector outputs a first signal when photon energy of the detected photons is within a first energy range and a second signal when photon energy of the detected photons is within a second energy range. The apparatus also includes an image controller configured to receive the first and second signal and obtain an energy-resolved scatter image data set. The energy-resolved scatter imaging improves the contrast and sensitivity for identification of different tissue types. Therefore, tumor tracking during radiation therapy and image guidance during radiotherapy are improved.
