Study Summary
The first goal of this project is to validate the superiority of semi-permanent marks used in conjunction with specialized light-based surface imaging (SIGRT) in an effort to phase out the use of permanent tattoos for the investigator's patients. The secondary goal of this project is to validate the superiority of specialized light-based surface imaging for daily radiation set-up compared to standard-of-care imaging methods using ionizing radiation, such as weekly port films or cone-beam CT (CBCT) scans during a radiation therapy course for breast cancer.
Primary Outcome
Distance measured (centimeters) from the planned position of radiotherapy to the actual position of radiotherapy on weekly port films. Port films are x-rays of the treatment field which are done to ensure that the patient and the radiation machine are properly aligned to each other. Weekly port films will be obtained for the duration of radiation treatment, which will be from three to five weeks in length.
Interventions
- OTHER Temporary skin markings
- OTHER Surface imaging
