CCD detector’s technology is one of the mainstream technologies used in DR products internationally; current domestic and international large-scale X-ray machine manufacturers gradually use CCD detectors to produce DR. The reflective single-CCD that New Standard medical NS-DR uses can reach up to a ultrahigh resolution of 17 million pixels (4096x4196), and has higher sensitivity and better image quality comparing to normal CCD detectors, representing the highest level of resolution in DR today.
