Subrina CYON X-ray CT scanner incorporating a solid-state detector

摘要

This report refers to our newly developed Subrina CYON whole-body X-ray CT scanner, which incorporates a solid-state detector, as a noteworthy feature. The important design philosophy of this new instrument is to minimize the radiation doses to patients and to improve the quality of images. The development has been made to reduce radiation doses without trading off the image quality required in diagnosis. The newly developed solid-state detector is designed to enhance density resolution, in contrast to the present detector, which are designed to ensure high spatial resolution. The net result is that the new detector ensures high quality of images, with minimized X-ray doses. Also, the newly developed Flex rnA function enables automatic optimizing of the X-ray tube current, from a single-direction slice planning image. The use of this function improves the image quality by optimizing the tube current and reduces the radiation doses to the patients. In addition, the Flex mA function provides two modes, automatic setting mode and radiation reduction mode, to be selected to ensure a wide field of clinical applications.
