Dose calculation method for multiple fields
First Claim
1. A computer implemented method of developing a treatment plan for the delivery of a desired dose of radiation to a treatment volume within a patient comprising:
- receiving the desired dose, the desired dose indicating a desired amount of radiation to deliver to the treatment volume over time;
calculating a first dose to be delivered over a first delivery time using a first number of control points, wherein the calculated first dose is generally similar to the desired dose; and
calculating a second dose using a second number of control points that is less than the first number of control points,wherein the second dose is delivered over a second delivery time, and wherein the second delivery time is less than the first delivery time.

Abstract
Systems and methods for developing a treatment plan for irradiating a treatment volume within a patient are disclosed. In accordance with the present invention, control points used to calculate a dose of radiation delivered to the treatment volume may be combined to result in a smaller number of control points. The smaller number of control points may allow more efficient calculation of dose distributions resulting in a treatment plan that can be delivered to the patient earlier or may allow additional iterations of treatment plan optimization resulting in a more accurate dose distribution being delivered to the patient.

6. A system for developing a treatment plan for the delivery of a desired dose of radiation to a treatment volume within a patient, the system comprising:
-
a processor; and a memory coupled to the processor, the memory including instructions that when executed by the processor cause the processor to perform steps including; receiving the desired dose, the desired dose indicating a desired amount of radiation to deliver to the treatment volume over time; calculating a first dose to be delivered over a first delivery time using a first number of control points, wherein the calculated first dose is generally similar to the desired dose; and calculating a second dose using a second number of control points that is less than the first number of control points, wherein the second dose is delivered over a second delivery time, and wherein the second delivery time is less than the first amount of time. - View Dependent Claims (7, 8, 9, 10)
