The dynamic phantom platform AZ-M1PP provides an economical, easy-to-use solution to the complex tasks associated with tumor motion and patient positioning in radiation therapy. The dynamic phantom platform is made of highly rigid, low-density plastic. It allows precisely controlled reciprocating motion (back and forth) up to 50mm for loadable phantoms (up to 52kg). Multiple types of dosimeters and phantoms can be placed on the AZ-M1PP and the moving target can be used for dose verification of treatment plans. An independently controllable body surface unit provides chest wall motion in the up and down directions.

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. Masaaki Yasue, President and CEO of Anzai Medical (December 2024)
“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.”
