President, Japan Association of Radiological Technologists


Yasuo Nakazawa, Ph. D.

We are honored that you kindly visited our website of the Japan Association of Radiological Technologists (JART). Since its foundation as on July 13th 1947, we have made a contribution to the development of national health, making full use of the technology in clinical radiology. As referred as “Without radiation, medicine is not possible”, the radiological examination and therapy are not only indispensable to medicine but also required to play an important role for the early detection of diseases and the cancer therapy management.

JART has been cooperating with the local associations in 47 prefectures and extending our activities to include participating in the health and welfare festival held nationwide to promote people’s health and welfare in Japan, free-of-charge consultation about radiation exposure through the sponsoring X-ray Week Events, trial palpation experience of mammography using phantoms, as well as free-of-charge bone density measurement. We have been constantly conducting educational enlightenment activities of the safety management of radiation in order to respond to the anxieties against the radiation. In October 2000, we proposed the guidelines for medical exposure (the lowest achievable level). Also in June 2015, we made “DRLs2015” public with the various associations. We have worked through for the optimization against medical exposure. In May 2007, we started a project for the certification system of facilities optimizing medical exposure dose. Presently, many institutions have been certified. Also, while conducting the consultation for the radiation exposure, with the cooperation with 47 prefectures for a long time, since 2015, we are now promoting for the overall radiation exposure consultation from citizens’ by defining the certified “consultants for radiation exposure”.

JART is expected to offer a high-quality image diagnostic and radiotherapeutic technology cooperating with citizens and medical professionals. We are required to respond immediately to the transformation of sociomedical system. We must do more support for the interpretation of radiological images by the diagnostic/therapeutic radiologists than in the past with the safety medical perspective and help reporting to the referring doctors. Concerning the explication/consultation in terms of the radiological examinations, we have to perform informed consents easily understandable by the patients based on evidence-based medicine. As for the radiotherapy, it is necessary to make plans and move into action the QC program of the instruments concerning irradiation. At the same time, we must check the radiation dosimetry and tackle the quality control issue. Above all, we really believe that we are required to offer the medical services more safe and secured with the cooperation with other medical staff.
