In the treatment of TrueBeam STx Cancer with radiotherapy, today the principle of “targeted irradiation” is used. By focusing on the cancerous cell in radiation therapy technologies, it is ensured that healthy cells are least damaged. The TrueBeam STx system is a new generation beam therapy technology. TrueBeam STx is used in Radiation Oncology to irradiate any tumor in every part of the body. System; Robotic imaging uses many technical innovations with automatic patient positioning, motion management, and completely reconstructed control features to dynamically synchronize therapy. It is generally used successfully in the treatment of tumors in hard-to-reach areas. TrueBeam STx can deliver higher doses in a short time in treatment, and in this respect, it significantly reduces the number of sessions and duration.
