Modern machines better focus the radiation and do less damage to normal tissues so doctors can use higher doses of radiation. Radiology oncology systems provides affordable high quality refurbished radiation therapy and diagnostic imaging equipment solutions including linear accelerators linacs ct scanners mri systems petct scanners ct simulators and more to facilities around the world increasing access to quality health care services for millions of patients.

Radiation therapy may be curative in a number of types of cancer if they are localized to one area of the body. Radiation therapy is a type of cancer treatment that uses beams of intense energy to kill cancer cells.
