该hx3捕捉数据不仅透过声音，而且还透过要么处在一个环形激光扫描器扫描短距离（最长可达4英尺） ，或二维成像扫描环覆盖距离达20英尺。
The HX3 captures data not only via voice, but also via either a SD laser ring scanner that scans short distance (up to 4 feet) or a 2D imager ring scanner that covers distances up to over 20 feet.
正电子断层扫描仪进行人体扫描的时候，病人被注入正电子放射性核素，然后推入检测环。
During a PET scan, the patient is injected with radioactive tracer molecules that emit positrons when they decay.
由于利用边缘检测使增长环搜寻所需的扫描范围在很大程度上缩小，最小不连续相位展开算法的效率得到了很大提高。
Because the required scanning range is cut down to a large extent by use of edge detection methods, the efficiency of the minimum-discontinuity phase unwrapping algorithm is significantly improved.
