Utility
Template Matching Method for Image-based Detection and Tracking of Irregular Shaped Targets
22 Sep 22
A method of generating a template image includes: receiving an input from a user representing identifications of an object in different respective slices of a volumetric image; using the input to determine a volume-of-interest (VOI) that includes voxels in a subset of the volumetric image; and determining the template image using at least some of the voxels in the VOI, wherein the act of determining the template image comprises performing a forward projection of the at least some of the voxels in the VOI using a processor.

Utility
Method and system for remote monitoring of proton beam emitting and delivery system
13 Sep 22
A remote diagnostic monitoring of operating states for physical components of a particle accelerator system includes obtaining, by a processor at a first physical location, one or more operating states corresponding to one or more physical components associated with a particle emitting system and a particle delivery system each located at a second physical location remote from the first physical location, associating the operating states with corresponding operating indicators, generating a component hierarchy corresponding to a physical arrangement of the physical components of the particle emitting system and including the corresponding operating indicators, identifying a faulted physical component among the physical components, identifying fault path components among the physical components, the fault path components corresponding to a portion of the physical arrangement associated with the faulted physical component, modifying the operating indicators of the fault path components to fault state indicators, and presenting a fault monitor presentation including the operating indicators and a faulted component presentation portion corresponding to the fault state indicators.

Adjoint transport for dose in treatment trajectory optimization for external beam radiation therapy
2 Aug 22
A method of trajectory optimization for radiotherapy treatment includes providing a patient model having one or more regions of interest (ROIs), defining a delivery coordinate space (DCS), for each ROI, solving an adjoint transport to obtain an adjoint solution field from the ROI, for each vertex in the DCS, evaluating an adjoint photon fluence by performing ray tracing of the adjoint solution field, evaluating a dose of the ROI using the adjoint photon fluence, for each vertex in the DCS, evaluating a respective beam's eye view (BEV) score of each pixel of a BEV plane using the doses of the one or more ROIs, determining one or more BEV regions in the BEV plane based on the BEV scores, determining a BEV region connectivity manifold based on the BEV regions, and determining one or more optimal treatment trajectories based on the BEV region connectivity manifold.
