Mohs micrographic surgery is the technique of surgically removing skin tumors by gradually excising thin layers and visualizing under a microscope till a tumor-free zone is obtained. During the surgical procedure, visible tumors are surgically removed. During the second stage, if tumor margins are clear with the positive specimen at depth, only depth cavitations need to be done without altering the tumor diameter. Defining the depth during this procedure is a major challenge due to the nonexistence of proper guidelines. Using the laser-induced breakdown spectroscopy (LIBS) technique, depth profiling can be performed precisely, preventing excessive tissue removal and reducing time consumption during the microscopic examination.
莫氏显微外科手术是一种通过逐步切除薄层皮肤肿瘤并在显微镜下观察直至获得无肿瘤区域来进行手术切除的技术。在手术过程中，肉眼可见的肿瘤会被手术切除。在第二阶段，如果肿瘤边缘与深部阳性标本边界清晰，则仅需进行深部空洞化处理，而不改变肿瘤直径。由于缺乏适当的指导方针，在此过程中确定深度是一项重大挑战。使用激光诱导击穿光谱（LIBS）技术，可以精确地进行深度剖析，避免过度切除组织，并减少显微镜检查期间的时间消耗。
