目的：利用计算机图像处理系统将平面的CT图像进行三维重建，并将这种重建出的图像与病理切片的病变范围相对照，评价这种三维重建的准确性。材料与方法：对50例未经治疗的喉癌患者，手术前进行螺旋CT扫描，将CT图像中的肿瘤病变范围进行标示，计算机三维重建，并与手术后结果及病理结果相对照。结果：螺旋CT图像三维重建可得到喉的立体图像，观察肿瘤的立体形态，这种图像可被赋予不同的色彩或半透明化，可沿X、Y、Z三维轴任意旋转、倾斜、切割、透明化等，以便寻找诊断的最佳视野。三维重建后T分期与手术后T分期的符合率为96%，手术安全缘保证率为98%。喉癌CT图像三维重建与病理对照显示了良好的相关性，对于手术前诊断，手术方案的设计都有一定的帮助。结论：喉癌CT图像三维重建与病理对照有良好的相关性，不仅可用于诊断，也可用于手术前的模拟手术和教学。

Objective:To investigate the value of the three-dimensional CT reconstruction by computer photo process system for laryngeal carcinoma and control study with pathologic feature. Methods: Fifty patients with laryngeal carcinoma were scanned by helical CT which photos were three-dimensionally reconstructed with a photo processing system,and the images were compared with pathologic feature.Results:Clear three-dimensional photo of the laryngeal was obtained through the reconstruction of the helical CT.The images could be circular fully around the axis of X,Y and Z in order to find the best view of the diagnosis.Ninety-six percentage of the TNM stage of patients according to the images of three-dimensional reconstruction were consistent with the TNM stage after operation.The safe edge was obtained in 98% of the surgery for patients.Good correlations were showed in the images of the three-dimensional reconstruction of the larynx and pathologic specimens.Conclusion:Good consistent of the three-dimensional images of the larynx with pathologic specimen were useful for diagnosis,operation design and education.
