图 1基于Mimics Research 19.0软件的术前术后患者不同肺叶容积的测量方法(以左上肺叶切除为例)A:术前;B:术后(注:红色:右肺上叶,黄色:右肺中叶,橙色:右肺下叶,蓝色:左肺上叶,粉色:左肺下叶)。
Different lung lobe volume labeling methods for preoperative and postoperative patients based on Mimics Research 19.0 software (left upper lobectomy as an example) A: preoperative, B: postoperative. (Note: red: right upper lobe, yellow: right middle lobe, orange: right lower lobe, blue: left upper lobe, pink: left lower lobe).
