Abstract
Disclosed herein are systems and methods for guiding the delivery of therapeutic radiation using incomplete or partial images acquired during a treatment session. A partial image does not have enough information to determine the location of a target region due to, for example, poor or low contrast and/or low SNR. The radiation fluence calculation methods described herein do not require knowledge or calculation of the target location, and yet may help to provide real-time image guided radiation therapy using arbitrarily low SNR images.
Claims21
A method for calculating a radiation dose for radiotherapy, the method comprising:
- acquiring a partial image xi of a target region using at least one positron emission detector;
- calculating a radiation fluence Fi to be delivered to the target region based on the partial image xi and a radiation-firing matrix P;
- and
- calculating a radiation dose using the calculated radiation fluence Fi and a computed tomography (CT) image.
