Title: The Innovative Contributions of Mineki Nishikawa
Introduction
Mineki Nishikawa is a notable inventor based in Tochigi, Japan. He has made significant contributions to the field of radiological sciences, particularly through his innovative patents. With a total of 5 patents, Nishikawa has demonstrated a commitment to advancing technology in scintillation cameras.
Latest Patents
Nishikawa's latest patents include a scintillation camera that features an arrangement for correcting non-linear responses. This invention involves storing reference correcting amounts during calibration mode at lattice points in a matrix. These points correspond to position signals from a radiation position calculation circuit, which are A/D-converted for every scintillation event. During measuring mode, the correcting amount is calculated based on reference amounts at each lattice point, ensuring accurate position signal application. Additionally, he developed a method for controlling scintillation cameras, which utilizes a CPU to displace a radiation source and measure the center of sensitivity of photomultiplier tubes. This method enhances the uniformity of the PMT response by comparing it with a reference response.
