A system and method of performing prospective and retrospective on-line adaptive radiotherapy. The method includes performing, during a treatment delivery session, delivery of a dose of radiation to an anatomical volume. The method includes detecting, during the treatment delivery session, a current state of the anatomical volume. The method includes predicting a future change in the current state of the anatomical volume during the treatment delivery session. The method includes adjusting, while the anatomical volume is in the current state, the treatment delivery to anticipate the future change in the anatomical volume.

Prospective and retrospective on-line adaptive radiotherapy

A radiation treatment delivery system, includes a linear accelerator (LINAC) and a multileaf collimator (MLC), coupled with the distal end of the LINAC, wherein the MLC has two banks of leaves, organized into a plurality of opposing leaf pairs. The system further includes a processing device, operatively coupled to the LINAC and the MLC, to control the plurality of leaf pairs of the MLC such that for each of a plurality of radiation beam delivery positional sections corresponds to a range of radiation beam positions over a discrete time interval that constrains an overall treatment time and wherein each leaf pair of the plurality of opposing leaf pairs is open to a fixed opening for a fraction of time in the discrete time interval and closed for the remaining fraction of time in the discrete time interval, while a radiation beam of the radiation treatment system is active.

Binary multileaf collimator delivery with per-leaf field width

A radiation treatment delivery system, includes a linear accelerator (LINAC) and a multileaf collimator (MLC), coupled with the distal end of the LINAC, wherein the MLC has two banks of leaves, organized into a plurality of opposing leaf pairs. The system further includes a processing device, operatively coupled to the LINAC and the MLC, to control the plurality of leaf pairs of the MLC such that for each of a plurality of radiation beam delivery positional sections corresponds to a range of radiation beam positions over a discrete time interval, wherein each leaf pair of the plurality of opposing leaf pairs is open to a fixed opening for a fraction of time in the discrete time interval and closed for the remaining fraction of time in the discrete time interval, while a radiation beam of the radiation treatment system is active.
