Combining X-ray and External Respiratory Signals for Real-Time Target Position Estimation
Real-time internal target position estimation is of high interest in radiotherapy, particularly with the recent development of robotic, linear accelerator, DMLC and couch-based systems which can continuously align the radiation beam with the target. This work combines x-ray and external respiratory monitoring sources to estimate real-time target position, facilitating highly accurate radiation delivery.
Applications
- To develop an algorithm to combine x-ray and external respiratory monitoring sources for estimating real-time target position.
Advantages
- No current system exists in radiotherapy to estimate internal position from a single x-ray imager and an optical system.
