First Claim
Patent Images
1. A method of evaluating a radiation dose delivered to a patient receiving radiation therapy, the method comprising using a computer to carry out the steps of:
- generating a 4D image set of the patient;
collecting a time-based series of data indicating patient motion;
evaluating a therapeutic radiation dose delivered to the patient based upon the 4D image set and the time-based series of data; and
acquiring radiation delivery machine parameter data to validate that the therapeutic radiation dose delivered to the patient was reasonable.

10. A system for determining a radiation dose delivered to a patient, the system comprising:
-
a radiation therapy treatment device including a computer processor, the radiation therapy treatment device operable to deliver radiation to a patient according to a treatment plan; and a software program stored in a computer readable medium accessible by the computer processor, the software being operable to receive a 4D image set of the patient, input a time-based series of data indicating patient motion, evaluate a therapeutic radiation dose delivered to the patient based upon the 4D image set and the time-based series of data, and acquire radiation delivery machine parameter data to validate that the therapeutic radiation dose delivered to the patient was reasonable. - View Dependent Claims (11, 12, 13, 14)

30. A method of evaluating a radiation dose to be delivered to a patient, the method comprising using a computer to carry out the steps of:
-
generating a time-based series of three-dimensional patient images; retrieving a simulated time-based series of data indicating patient motion; and evaluating a therapeutic radiation dose that would be delivered to the patient based upon the time-based series of three-dimensional patient images and the simulated time-based series of data.
