Dose calculation method for multiple fields |
摘要 |
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. |

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 to the treatment volume over a first delivery time using a first number of control points, wherein the calculated first dose is within a specified degree of accuracy of the desired dose; and calculating a second dose to be delivered to the treatment volume, wherein the second dose is delivered over a second delivery time, the second delivery time being less than the first delivery time. |
