由河北省医院和石家庄市华亚光电器材厂联合研制的HY型医用多功能彩色显示器(或称彩色编码仪),由河北省科学技术委员会、河北省卫生厅、河北省医药总公司于一月十五日组织并通过技术鉴定。 HY型医用多功能彩色显示器,是应用视频处理技术将影像诊断提供的(B型超声诊断仪、X线电子计算机控制体层扫描—CT、核磁共振—NMR、X线数字减影——DSA、心血管造影等)灰阶信号,经不同色量等编码和处理,使原来以黑白灰阶显示的图像转变成为彩色图像。由于它可将灰阶显示只能分辨30分贝的可视
By the Hebei Provincial Hospital and Shijiazhuang City, China and Asia Optoelectronic Equipment Factory joint development of the HY-medical multi-function color display (or color encoder) by the Hebei Provincial Science and Technology Commission, Hebei Provincial Health Department, Hebei Pharmaceutical Corporation in January On the 15th organized and passed the technical appraisal. HY-type medical multi-function color display is the application of video processing technology to provide diagnostic imaging (B-type ultrasound scanner, X-ray computed tomography - CT, NMR - XMR digital subtraction - DSA, Angiography, etc.) gray-scale signals, encoded by different colors and processing, so that the original black and white gray-scale images displayed into a color image. Because it can be gray-scale display can only distinguish 30 dB of visual
