Abstract

A treatment planning, simulation, and verification system is described. According to one embodiment, a treatment plan and a fluoroscopy data image of a treatment volume are received and the treatment plan is automatically adjusted based on the movement of the fluoroscopy data image. According to another embodiment, a system includes a treatment planning component to generate a treatment plan and a simulation component to simulate the execution of the treatment plan.

Claims

1. A method of adjusting a radiotherapy simulator system comprising:

displaying a digital image of a patient based on a treatment plan;

providing input associated with the digital image; and

automatically adjusting one or more components of the radiotherapy simulator system based on the input associated with the digital image.

2. The method of claim 1, wherein displaying the digital image includes overlaying a simulator digital image and a digitally reconstructed radiograph image.

3. The method of claim 2, further comprising:

automatically displaying fields of data based on the digital image.

5. The method of claim 1, wherein the providing includes providing a radiation field input.

4. The method of daim 1, further comprising:

recalculating the treatment plan based on the input associated with the digital image; and

saving the recalculated treatment plan.

6. A machine-readable medium having instructions to cause a machine to perform a method of adjusting a radiotherapy simulator system, the method comprising:

displaying a digital image of a patient based on a treatment plan;

providing input associated with the digital image; and

automatically adjusting one or more components of the radiotherapy simulator system based on the input associated with the digital image.

7. The machine-readable medium of claim 6, wherein displaying the digital image includes overlaying a simulator digital image and a digitally reconstructed radiograph image.

8. The machine-readable medium of claim 7, further comprising:

automatically displaying fields of data based on the digital image.

9. The machine-readable medium of claim 6, further comprising:

recalculating the treatment plan based on the input associated with the digital image; and

saving the recalculated treatment plan.

10. The machine-readable medium of claim 6, wherein the providing includes providing a radiation field input.
