CARBON ION RADIOTHERAPY

Precision radiotherapy technology:
carbon ion radiotherapy

Carbon ion therapy is a type of radiotherapy that uses carbon ions. Treatment is planned considering the positions of the lesion and normal tissue, and whether it can be applied is decided by physicians after a comprehensive assessment of each patient.

  • Particle therapy is divided into proton therapy and carbon ion therapy.
  • In Japan, clinical research on carbon ion radiotherapy began in 1994 at the National Institute of Radiological Sciences (now QST).
