超声图像的H扫描分析是一种匹配滤波器方法，其来源于以高斯加权厄米多项式函数形式的入射脉冲散射分析。该框架应用于甲状腺病变的初步研究中，以检查三类H扫描输出：正常甲状腺，良性病变和癌性病变，总组大小为46例患者。此外，幻影组成的球形散射体进行了分析，以建立独立的参考值进行比较。结果表明，不同组之间的H扫描通道输出的一些测量值存在微小但显著的差异。
The H-scan analysis of ultrasound images is a matched-filter approach derived from analysis of scattering from incident pulses in the form of Gaussian-weighted Hermite polynomial functions. This framework is applied in a preliminary study of thyroid lesions to examine the H-scan outputs for three categories: normal thyroid, benign lesions, and cancerous lesions within a total group size of 46 patients. In addition, phantoms comprised of spherical scatterers are analyzed to establish independent reference values for comparison. The results demonstrate a small but significant difference in some measures of the H-scan channel outputs between the different groups.
