Radiotherapy is the treatment of cancer through the irradiation of tumor using ionizing energy. This can be introduced to the body using radioactive sources (brachytherapy) and particle accelerators (teletherapy). The goal of radiation therapy is to deliver the highest close to the tumor while minimizing the exposure to the surrounding healthy cells (Optimization). However, limitations in the conventional instruments provide unnecessary exposures due to beam geometry, patient/organ movement (voluntary and involuntary), and nature of radiation beam. In response, oncologists and physicists perform methods to minimize exposure to organs at risk such as three-dimensional conformal radiotherapy, stereotactic radiosurgery, image-guided radiotherapy, and spot scanning particle beam therapy. Aside from these, a new technique called Real-time Tumor-tracking Radiation Therapy (RTRT) coupled with a proton accelerator (Real-time-image Gated Proton bean Therapy or RGPT) was developed by Hokkaido University. This new technology has shown a dramatic increase in radiation precision. The principles behind RTRT and RGPT as well as their advantages over previous radiotherapies will be discussed in this talk.
