Studies of daily anatomic change and tumor position for adaptive radiation therapy
This study would be an analysis of the existing images acquired during radiation therapy treatment between 1/1/2006 to 3/13/2012 and treatment images of patients who will be treated between 3/14/2012 to 12/31/2016. We use readily images for the patient tumor and will reconstruct (using special softwares) volumetric images to observe and study daily anatomy at treatment position prior to treatment and observe and study tumor motions prior to and during treatment. this will not affect patient treatment. (we will used im A new dose distribution will be calculated based on the original treatment plan and the daily anatomy. Adaptive radiation therapy plan may be generated for comparison. Details dose coverage for target and regions of interest will be studied for original plan, original plan on daily anatomy, and adaptive plan.
Retrospective Component - UT-Southwestern patients who have undergone radiation therapy from 1/1/2006 to 3/13/2012.
Prospective Component x UT-Southwestern patients who will be undergone radiation therapy from 3/14/2012 to 12/31/2016.
