Estimating the term…
In a radiation treatment plan that includes a plurality of treatment fields of multiple treatment modalities, such as IMRT modality and dynamic treatment path modality (e.g., VMAT and conformal arc therapy), an optimized spatial point sequence may be determined that optimizes the total treatment time, which includes both the beam-on time (i.e., during the delivery of radiation dose) and the beam-off time (i.e., during transitions between consecutive treatment fields). The result is a time-ordered field trajectory that intermixes and interleaves different treatment fields. In one embodiment, a dynamic treatment path may be cut into a plurality of sections, and one or more IMRT fields may be inserted between the plurality of sections.
A computer-implemented method of determining a treatment field trajectory for delivering a desired dose of radiation to a treatment volume within a patient using an external-beam radiation treatment system, the method comprising:
A computer product comprising a non-transitory computer readable medium storing a plurality of instructions that when executed control a computer system to determine a treatment field trajectory for delivering a desired dose of radiation to a treatment volume within a patient using an external-beam radiation treatment system, the instructions comprising:
