Various embodiments disclose systems and methods for tracking regions (e.g., tumor locations) within living organisms. Some embodiments provide real-time, highly accurate, low latency measurements of tumor location even as the tumor moves with internal body motions. Such measurements may be suitable for closed-loop radiation delivery applications where radiation therapy may be continuously guided to the tumor site even as the tumor moves. Tumor motion may be associated with periodic motion (e.g., respiratory, cardiac) or aperiodic motion (e.g., gross patient motion, internal bowel motion). Various embodiments facilitate accurate radiation delivery to tumor sites exhibiting significant motion, e.g., lung, breast, and liver tumors.

Systems and methods for real-time tumor tracking

A method of detecting a possible collision in a medical procedure that involves a medical system, includes: obtaining an image of a patient that is supported on a patient support; determining a first model using a processing unit based at least in part on the image, at least a part of the first model representing a surface of the patient; determining a second model using the processing unit, the second model representing a first component of the medical system; virtually moving the first model, the second model, or both, using a collision prediction mechanism to simulate a movement of the first component of the medical system to determine whether there is a possible collision between the first component and the patient; and generating an output to indicate the possible collision or an absence of the possible collision.
