Current techniques for imaging chest deformity are limited to two-dimensional representations, and clinical testing for lung volume measurements are based on pulmonary function studies that are effort-dependent. The authors evaluated spine deformity and lung volume by using a new three-dimensional microcomputer imaging technique. Results from preoperative and postoperative chest computed tomograms underwent boundary detection by expert human observers. Data were then processed by polygon surface tiling to create three-dimensional color images of the spine and lungs for display. This computer technique allowed: 1) visualization of the anatomic relationships from any angle, 2) assessment of spinal deformity in relation to lung volume, and 3) measurement of individual lung volumes. Three-dimensional microcomputer imaging is a useful technique in objectively measuring lung volume and assessing postoperative changes.
目前用于胸部畸形成像的技术仅限于二维图像，而肺容量测量的临床检测则基于依赖用力的肺功能研究。作者使用一种新的三维微机成像技术评估脊柱畸形和肺容量。术前和术后胸部计算机断层扫描的结果由专业人员进行边界检测。然后通过多边形表面平铺处理数据，以创建脊柱和肺部的三维彩色图像进行显示。这种计算机技术可以：1）从任何角度可视化解剖关系；2）评估与肺容量相关的脊柱畸形；3）测量个体肺容量。三维微机成像技术是客观测量肺容量和评估术后变化的一种有用技术。
