Method And System For Using Cherenkov Radiation To Monitor Beam Profiles And Radiation Therapy |
摘要 |
A system for providing monitored radiation therapy has a high energy radiation source, apparatus for excluding uncontrolled ambient light, and apparatus for collecting light emitted from a subject. The system has apparatus for spectrally analyzing the collected light, and a processor for determining oxygenation or other metabolic function of tissue within the subject from spectral analysis of the collected light. The system monitors radiation therapy by providing a beam of high energy radiation; collecting Cherenkov and/or photoluminescent light from the subject, the light generated along the beam; spectrally analyzing the light; and determining oxygenation or metabolic function of tissue from the spectral analysis. Beam profile of the system is calibrated by imaging from multiple angles Cherenkov and/or photoluminescent light emitted by a phantom placed in the beam in lieu of a subject, captured images are analyzed to determine beam profile. |
