Abstract:

鸡胸是最常见的儿童胸壁畸形之一,表现为部分胸骨及与之相连的肋软骨向前突起,轻者心理健康受损,重者肺部等身体机能受损。临床上广泛使用的鸡胸评价指标——Haller 指数,其在鸡胸诊断效率以及分型上存在一定不足,因此本文提出一种改进型 Haller 指数及其自动化测量算法。首先提取患者电子计算机断层扫描(CT)图像中胸骨最凸横断面的外胸廓像素点集合;然后将其分别拟合为三次 B 样条曲线和椭圆曲线;最后基于解析曲线自动计算得出改进型 Haller 指数及分型指数。通过对 22 组患者术前术后 CT 数据的实验分析结果表明,本文提出的改进型 Haller 指数不仅可以正确诊断鸡胸,而且可用于对不同程度的鸡胸进行分型,证实了该评价指标的可行性,同时由于采用计算机自动测量技术,提高了鸡胸诊断效率,为计算机辅助个性化儿童胸壁畸形诊疗技术奠定了基础
