Canon Medical, Hiroshima University Begin PCCT Research Collaboration

Canon Medical Systems Corporation and Hiroshima University have initiated clinical research using a Canon photon-counting CT (PCCT) system with the aim of rapidly advancing its practical application. The two organizations are exploring the clinical usefulness of data captured by PCCT, evaluating and optimizing various kinds of diagnostic information provided by PCCT, and determining imaging protocols, in order to maximize the functionality of PCCT from a basic level to clinical applications.

A PCCT system is a diagnostic imaging system equipped with a next-generation detector (photon-counting detector) capable of collecting data by identifying the energy of incident X-rays. Unlike conventional X-ray CT, PCCT can differentiate multiple material compositions and is expected to improve diagnostic accuracy by providing superior quantitation. In addition, with the higher resolution of PCCT, the detectability of lesions should be further improved at even lower exposure doses.

Canon Medical and Hiroshima University will accelerate development of PCCT by feeding back the results of this clinical research into improvement of the system. Through the early implementation of PCCT, which brings together various technologies cultivated by Canon over the years, Canon Medical will aim to contribute to the further development of diagnostic imaging technology.

The latest information on the company’s PCCT was presented at the International Technical Exhibition of Medical Imaging 2024 (ITEM2024) to be held in Yokohama from April 12 to April 14, and at the 83rd Congress of the Japan Radiological Society and the 80th Congress of the Japanese Society of Radiological Technology, which are also to be held in Yokohama, from April 11 to April 14.
