Abstract
Systems, methods, and computer-readable storage media providing techniques for probing in-vivo beam ranges directly using therapeutic beams for particle therapy treatment are disclosed. In an embodiment, a configuration is determined for one or more probing spots, each spot corresponding to a planned location within an interior region of a tumor volume where a dose of radiation is to be delivered. At least one therapeutic beam is provided to the tumor volume, and one or more images may be captured to provide an indication of the range/depth of the probing spots. Providing the probing spots to the interior of the tumor volume reduces the risk that the dose is provided to sensitive tissue (e.g., because even if the dose is delivered to a location other than the planned location, the dose is likely to remain contained within the tumor volume).
