    摘要： Disclosed herein are methods and systems for calculating radiation therapy treatment plan (RTTP) including a method that comprises monitoring, by a processor, a treatment plan optimizer computer model to identify a set of treatment plans, where the treatment plan optimizer computer model ingests a set of medical images and predicts each treatment plan comprising a respective range of angles for treatment beam entry; generating, by the processor, a training dataset comprising the monitored data; and training, by the processor, a machine learning model using the training dataset to predict a new range of angles for treatment beam entry for a new patient by ingesting new patient data of the new patient.

    摘要： A control circuit accesses information regarding a given patient. That information may include, for example, segmentation information that depicts at least one treatment volume and at least one organ-at-risk. The control circuit then defines a plurality of dose-calculation sectors for the given patient as a function, at least in part, of the information regarding the given patient. Those dose-calculation sectors are not assumed to be uniformly sized. These teachings can then provide for optimizing a radiation treatment plan, such as a volumetric modulated arc therapy radiation treatment plan, as a function, at least in part, of the plurality of dose-calculation sectors to provide an optimized radiation treatment plan.

    摘要： A control circuit accesses information for a given patient (for example, image information corresponding to a target volume and/or an organ-at-risk) as well as characterizing parameters for a given radiation treatment platform (for example, gantry angles). The control circuit can then optimize a radiation treatment plan for the given patient using the given radiation treatment platform as a function, at least in part, of the information for the given patient, the characterizing parameters for the given radiation treatment platform, and a generalized metric type comprising generalized Equivalent Uniform Dose (gEUD)-of-extreme to provide an optimized radiation treatment plan.

    摘要： A computer implemented method of developing a radiation treatment plan comprising spot scanning of a treatment target comprising accessing information associated with a patient and information pertaining to a radiation delivery machine. The method further comprises determining an area associated with the treatment target, wherein the area comprises a plurality of spots and computing a weighting for each spot of the plurality of spots, wherein the weighting is associated with a number of protons delivered at a respective spot. Further, the method comprises computing timing related parameters based on information retrieved from the radiation delivery machine and determining a transition dose delivered by the radiation delivery machine during the transition from one spot to another spot when irradiating the treatment target.

    摘要： A control circuit generates an optimized radiation treatment plan with respect to an adjustable collimation device and then automatically generates at least one quality assurance accuracy value corresponding to the optimized radiation treatment plan. By one approach, the aforementioned plan comprises a plurality of treatment fields. In such a case, automatically generating at least one quality assurance accuracy value can comprise, at least in part, automatically generating at least one quality assurance accuracy value for each of at least a substantial number (or all) of those treatment fields. By one approach, the aforementioned quality assurance accuracy value comprises a dimensionless metric. This dimensionless metric may represent, for example, dosimetric accuracy corresponding to the optimized radiation treatment plan.

    摘要： Systems and methods for radiation treatment planning can include a computing system receiving one or more indications of one or more clinical objectives for a radiotherapy treatment plan, and determining, for each clinical objective, a corresponding quality metric interval. The computing system can determine within each quality metric interval, a corresponding sub-score function having a derivative determined based on one or more priorities of the one or more clinical objectives, and determine a quality score function for the radiotherapy treatment plan by aggregating sub-score functions within quality metric intervals corresponding to the one or more clinical objectives. The computing system can use the quality score function to adjust one or more parameters of an objective function for optimizing the radiotherapy plan.
