Intensity-Modulated Brachytherapy (IMBT) system that directionally controls dose via W-shield rotation — delivering highly conformal tumor dose while minimizing OAR exposure.
Brad-FIT (Brachy RADiation FIT) is an Intensity-Modulated Brachytherapy (IMBT) system that directionally controls dose distribution by rotating an asymmetric tungsten shield (W-shield). The shield rotates to any arbitrary angle with sub-1-degree resolution, creating an asymmetric dose distribution concentrated toward the tumor, while a dedicated Treatment Planning System (TPS) performs DVH-based dose optimization. Two applicator types are available: a tandem applicator for cervical and endometrial cancers, and a cylindrical applicator for breast and vaginal cancers.
Brad-FIT's non-invasive design minimizes anesthesia requirements compared to conventional brachytherapy applicators, with shorter treatment preparation time and minimal manpower. While competing applicators from Elekta, Varian, and E&Z Bebig require invasive insertion and skill-dependent accuracy, Brad-FIT delivers precise, reproducible treatment through directional control and an optimized TPS — independent of operator technique.
The directional radiation control technology is protected by patents in Korea (2017), Europe, China, and Japan (2020), and the USA (2021). Additional patents cover directional and shape-controllable radiation (Korea 2019, China/Japan 2021, USA 2022) and the brachytherapy planning device and method (Korea 2021, USA 2024).
