A Breast Immobilization Device that Improves Radiation Therapy Dosimetry
- Technology Benefits
- Increased accuracy of radiation dosimetryLower normal tissue toxicityEasy operation and modificationInexpensiveIncreased patient comfort
- Technology Application
- External beam radiotherapy treatments of the breast
- Detailed Technology Description
- The technology creates a patient-specific mold without using any rigid material to provide support for the breast. The device is easy to set up and remove, can be altered for different breast morphologies, and does not build up excess skin unlike current device technologies.

Background
Breast setup and immobilization is a difficult problem for external beam radiation therapy of breast cancers. A lack of setup reproducibility with breast tissue results in sub-optimal dosimetry and tissue toxicity in non-targeted, healthy tissues.Patients with larger or pendulous breasts, which are pulled down by gravity into close proximity of healthy organs, experience more non-target toxicity and higher skin doses of radiation.Devices previously designed to support breast tissue and create space from the chest for safer radiotherapy have suffered from patient discomfort and skin build-up.
