Abstract
Method and system aspects for increasing resolution of a radiotherapy system to achieve virtual fractional monitor unit radiation delivery are described. Included in a method aspect, and system for achieving same, is identification of a desired treatment dose, the desired treatment dose exceeding a resolution of a radiation treatment device. Further included is the development of a schedule of treatment sessions for delivering the desired treatment dose by the radiation treatment device that produces a combined treatment dose equaling the desired treatment dose without exceeding the resolution within each treatment session.
Claims26
A method for effectively increasing resolution of a radiotherapy system, the method comprising:
- identifying a desired treatment dose, the desired treatment dose exceeding a resolution of a radiation treatment device;
- and
- developing a schedule of treatment sessions for delivering the desired treatment dose by the radiation treatment device that produces a combined treatment dose equaling the desired treatment dose without exceeding the resolution within each treatment session.
A radiotherapy system with increased dose unit resolution, the system comprising:
- a radiation treatment device, the radiation treatment device delivering radiation at a set resolution;
- and
- a treatment processing unit coupled to the radiation treatment device and including a control unit for identifying a desired treatment dose, the desired treatment dose exceeding the set resolution, and for developing a schedule of treatment sessions for delivering the desired treatment dose that produces a combined treatment dose equaling the desired treatment dose without exceeding the set resolution within each treatment session.
A method for effectively increasing dose unit resolution of a radiotherapy system, the method comprising:
- (a) identifying a desired treatment dose, the desired treatment dose exceeding a resolution of a radiation treatment device;
- (b) identifying the resolution of the radiation treatment device;
- (c) determining a first dose based on the resolution and the desired treatment dose;
- (d) determining a second dose based on the resolution and the first dose;
- (e) determining a first number of days at the first dose;
- and
- (f) determining a second number of days at the second dose, wherein the delivery of the first dose for the first number of days and delivery of the second dose for the second number of days provides the desired treatment dose.
