Abstract: Methods, apparatuses, systems, and implementations for creating a patient-specific soft bolus for radiotherapy treatment are disclosed. 2D and/or 3D images of a desired radiotherapy treatment site may be acquired, such as the head, neck, skin, breast, anus, and/or vulva. A user may interact with one or more representations of the images via an interactive user interface such as a graphical user interface (GUI). The images may include target/avoidance structures and radiation beam arrangement. The user may interact with the images to create a visualization of a patient-specific bolus. The visualization and properties of the bolus may be modified as the user manipulates aspects of the image. Data corresponding to the bolus models may be used to create 3D printed negative molds of the bolus model using 3D printing technology. A soft patient-specific bolus may be cast using the 3D printed model.

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).
