| Outline of Final Research Achievements |
We performed four themes for the development of new low-absorption material devices in radiation therapy and achieved the following research.
1. We developed a novel low-radiation-absorbent (LAA) lok-bar (HM-bar) that is used to secure the immobilizers to couch. It can be used for patient therapy at hospitals to provide accurate dose delivery. 2. We developed a novel LAA immobilization adaptor (HMA), which can be used for head and neck region in radiotherapy. 3. An ideal couch material needs to have high permeability and low potential for sagging and should adequately support a patient. We developed the new couch, carried out verification of reference beam profiles for preconfigured Halcyon. 4. We developed a novel less-radiation beam pass and LAA immobilizer (U-frame) for stereotactic body radiotherapy. We have performed dazzling achievements such as, papers (5), patents (2) and regulatory approval (1), much progress and advancement has been made for radiotherapy in three years.
