Dallas-based ProtectMed LLC received a patent for a radiation shield that protects healthcare workers’ breast, underarm and thyroid tissue. The award came the week of Sept. 1, a week when North Texas ranked No. 10 among 250 metro areas for patent production.

The patent names three inventors: Dallas interventional radiologist Chet Rees, Fort Worth breast surgical oncologist Lauren Ramsey and Ryan Baldwin of Seattle. The design closely matches BAT, a lightweight radiation protection garment designed to safeguard the breast, axilla and thyroid of healthcare workers.

Ramsey serves as CEO and co-founder of ProtectMed LLC, which licenses the BAT technology to Virginia-based Burlington Medical. Ramsey and Rees discussed the design in a video on the Burlington Medical website.

“I had a friend and a colleague who died from breast cancer at a young age. She was an orthopedic surgeon so was around a lot of radiation exposure. It prompted me to do a lot of research,” Ramsey said. “…I hope that we’re able to educate people about the risk of radiation exposure and breast cancer and able to provide physicians and other healthcare providers with a way to reduce that risk and hopefully reduce the risk of breast cancer.”

In a research study, Rees and colleagues at Baylor University Medical Center tested the BAT shield on an anthropomorphic acrylic female torso in a simulated procedure room. The results were published in the journal Health Physics.
