Dynamic X-Ray Imaging and Analysis System

Abstract

Dynamic X-ray imaging and analysis system has received JAMIT Technological Achievement Award. The imaging system is consisted of a dynamic flat-panel detector with a large field of view and X-ray generator/tube capable of pulsed irradiation. For the evaluation of pulmonary function, the movement of the diaphragm, rib cage, and structures in the lungs, as well as density changes in the lung field due to respiration and pulmonary blood flow, are quantified and visualized on the obtained dynamic chest radiographs. The product was commercialized in November 2018 through animal testing and initial clinical research through industry-academia-government collaboration. The system is in operation at approximately 70 facilities in Japan (as of February 2023), and its usefulness in various functional diagnoses has been reported in many cases. This paper describes an overview of a dynamic X-ray imaging and analysis system that realizes lung function imaging in the general radiography room, and perspectives on this field.
