Dr. Takashi Ogino Director, International Proton Therapy Center Connection Device: Proton therapy device (Mitsubishi Electric) Purpose of use: Respiratory gated irradiation of lung and liver tumors
Dr. Ogino has been witnessed the establishment of the National Cancer Center East Hospital, which was the first proton therapy facility dedicated to medical treatment in Japan in 1996, and has been involved with Anzai Medical’s respiratory gating system for more than 10 years. Respiratory gated irradiation is indispensable for the treatment that obtains the effect of radiation focused on cancer lesions while reducing the effect on normal tissues, which is a characteristic of proton beam therapy. We would like to introduce the comments from Dr. Ogino who has lots of clinical experience. “In the early days of Anzai Medical’s respiratory gating system, handling the respiratory sensor was sometimes difficult, but with the current laser sensor, it is easy to administer to the patient, and the obtained respiratory waveform also correlates with the target. I am convinced that respiratory-gated irradiation is generally said to be longer and more inefficient than regular irradiation, but it does not take much time in cooperation with the patient. Rather than pointing out that the efficiency of the treatment time is reduced by performing respiratory-gated irradiation, the side effect of irradiating the human body with radiation (normal tissue) It seems that there is a relative risk in the treatment that does not make use of the characteristics of the proton beam, which can suppress the inflammation of cancer and the cancer that arises from low exposure).It is very strange for me that there are few examples of Respiratory sync irradiation”.

Dr. Tsujii is one of the world’s most authoritative doctors in heavy ion radiotherapy, having served as Director of the Heavy Particle Medical Science Center and Director of the hospital at the National Institute of Radiological Sciences (NIRS), which was the first in the world to successfully put heavy ion radiotherapy into practical use in 1994. We are very proud to receive the following comment from such an authoritative doctor about the M1 PP, which is scheduled to be released by our company as a new product, and intend to use it to further our sales activities.

“This Dynamic Phantom Plate is an innovative product that enables high precision and flexible responses in quality management for respiratory-synchronized irradiation methods. Its novel cable-free design makes it easier to handle compared to conventional devices, allowing for easy verification with phantoms of various sizes and weights. This product can be utilized across a wide range of fields, including photon therapy and particle therapy, and serves as a groundbreaking tool for accurately assessing irradiation performance for tumors that experience respiratory motion. In the field of particle therapy, where I have been highly involved for many years, the precision and usability of this product are regarded. It is undoubtedly set to become an essential device in future treatment settings, particularly for its contribution to improving the accuracy of respiratory-synchronized irradiation.”
