Abstract
Systems and methods for radiation therapy planning are described. A radiation therapy includes of a series of radiation treatment fractions each including a sequence of radiation segments with a prescribed cumulative dose intensity profile to be delivered to a therapy site on a patient. In one embodiment, a pair of consecutive radiation treatment fractions is generated, wherein each fraction has a different set of radiation segments. A system, a computer program, and a computer-readable medium carrying instructions for radiation therapy planning also are described. The system, computer program, and computer-readable medium each are operable to combine common radiation segments of two radiation treatment fractions to reduce the total number of radiation segments applied to the patient.

A method of planning a radiation therapy comprising of a series of radiation treatment fractions each comprising a sequence of radiation segments with a prescribed cumulative dose intensity profile to be delivered to a therapy site on a patient, the method comprising generating a pair of consecutive radiation treatment fractions each comprising a different set of radiation segments.
A system for planning the application of a series of radiation treatment fractions each comprising a sequence of radiation segments with a prescribed cumulative dose intensity profile to be delivered to a therapy site on a patient, the system comprising a computer operable to combine common radiation segments of two radiation treatment fractions to reduce the total number of radiation segments applied to the patient.
A computer-readable medium carrying instructions for planning the application of a series of radiation treatment fractions each comprising a sequence of radiation segments with a prescribed cumulative dose intensity profile to be delivered to a therapy site on a patient, the instructions comprising the step of combining common radiation segments of two radiation treatment fractions to reduce the total number of radiation segments applied to the patient.
A computer program for planning the application of a series of radiation treatment fractions each comprising a sequence of radiation segments with a prescribed cumulative dose intensity profile to be delivered to a therapy site on a patient, the computer program residing on a computer-readable medium and comprising computer-readable instructions for causing a computer to combine common radiation segments of two radiation treatment fractions to reduce the total number of radiation segments applied to the patient.
A system for delivering a series of radiation treatment fractions each comprising a sequence of radiation segments with a prescribed cumulative dose intensity profile to be delivered to a therapy site on a patient, the system comprising:
- a radiotherapy device configured to generate a sequence of radiation segments;
- and
- a computer programmed to combine common radiation segments of two radiation treatment fractions to reduce the total number of radiation segments applied to the patient, the computer being further programmed to control the delivery of radiation segments to the patient.
