Since more than a decade BEC cooperates closely with leading treatment centers and research institutes in radiotherapy. Based on this massive experience and knowledge we designed a system that complies with or even exceeds the requirements for future patient positioning. With exacure we offer a cutting-edge system that flexibly combines robotic patient positioning with additional modules for high-end radiotherapy.
Components with high radiation resistance for BNCT
The requirements for medical devices that are used for BNCT treatment differ substantially from the requirements for systems used in conventional radiotherapy, as material properties are degraded by the neutron irradiation. Depending on the spectrum of the neutrons the exposure limits the life time of components or makes them even unsuitable for BNCT treatment. The exacure system from BEC is currently the only certified medical device available that meets those challenging requirements and ensures patient safety during BNCT treatment with the full range of functions, including patient positioning and imaging.
Boron Neutron capture therapy (BNCT) is a unique non-invasive type of radiation therapy for treating tumors with a two-step procedure*. First, the patient is injected with a tumor-seeking drug containing a non-radioactive isotope (boron-10) with a high neutron capture cross-section. In the second step, the patient is exposed to a beam of low energy neutrons. After losing energy as they penetrate tissue, the neutrons are captured by the boron, which subsequently emits high-energy alpha particles that can selectively kill those tumor cells that have taken up sufficient quantities of boron. Scientific studies** demonstrate that these particles systematically destroy the tumor cells while imparting relatively little damage to adjacent areas of healthy tissue. BNCT can make the process of radiation treatment much less onerous for the patient and has the potential to greatly improve therapeutic outcomes by treating the primary tumor site as well as undetected metastases in local region of the tumor.

"Irradiating a tumor accurately while sparing the surrounding healthy tissue, calls for the ultimate solution in patient positioning technology. Transferring cutting-edge technology from industrial applications to medical robotics was a key factor to the successful development of the exacure system."
