Title: Innovations by Yukio Kumagai
Introduction
Yukio Kumagai is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of X-ray technology, holding a total of 5 patents. His work focuses on enhancing the efficiency and effectiveness of X-ray CT apparatuses.
Latest Patents
Kumagai's latest patents include an innovative X-ray CT apparatus and scanning method. This invention aims to provide an optimal X-ray dose for dynamically changing X-ray irradiation regions. The apparatus is designed to reliably irradiate the X-ray region when X-rays are applied with a spreading angle in the body axis direction. It dynamically adjusts the X-ray irradiation region for each view angle during scanning. Additionally, a system control device modifies the position of an analysis line used to calculate the optimal tube current during scanning, ensuring the best possible irradiation dose.
Another notable patent is the X-ray CT apparatus and tomography method. In this invention, a tube current value calculation unit determines the tube current value of an X-ray tube based on successive approximation process conditions and input scanning or reconstruction conditions. The scanning control unit then performs scanning based on the calculated tube current value, while the image reconstruction unit reconstructs a tomographic image of the object. This process is based on the amount of transmitted X-rays detected after being emitted from the X-ray source.
