ChabnerXRT provides a radiolucent breast immobilization bra for radiation therapy that enables precise visual and laser alignment while reducing heart and lung exposure, especially for patients with larger or pendulous breasts. The see‑through mesh allows clinicians to verify positioning without removing the device and integrates with surface‑guided radiation therapy systems for real‑time monitoring. Clinical data show consistent breast positioning, shorter therapist setup times, and markedly lower skin reactions compared with traditional netting or tape.

Problem
Patients with large or pendulous breasts often experience inconsistent positioning during radiation therapy, leading to increased heart and lung exposure and higher rates of skin toxicity. Traditional immobilization methods such as netting or tape provide limited visual confirmation and can be time‑consuming for therapists.
Solution
ChabnerXRT offers a radiolucent, see‑through breast immobilization bra designed for use in radiation therapy. The mesh construction enables direct visual and laser alignment without removing the device, ensuring reproducible breast positioning across treatment fractions. By stabilizing the breast, the bra reduces incidental dose to the heart and lungs and minimizes skin erythema and desquamation compared with conventional methods. The device is compatible with surface‑guided radiation therapy (SGRT) systems, allowing real‑time monitoring and verification of patient setup. Clinicians benefit from shorter therapist setup times and more consistent treatment delivery, improving overall treatment quality for patients with larger breast sizes.
Target Audience
Primary users are radiation oncologists, medical physicists, and radiation therapy technologists who treat breast cancer patients, especially those with larger breast volumes.
