A cinevideodensitometric method for measuring the dimensions of small vessels by computer analysis of digitized cineangiograms was developed and validated in radiographic phantom models. With this method, which is based on full-width-at-half-maximum analysis of videodensitometric profile curves, the diameters of contrast-filled plexiglass cylinders ranging from 1.78 mm to 4.14 mm in diameter were measured to within 2% mean error. The theoretical basis for this method of cinevideodensitometric analysis is provided.
一种通过对数字化血管造影电影进行计算机分析来测量小血管尺寸的电影视频密度测定法，已在放射摄影体模模型中得到开发和验证。该方法基于视频密度测定轮廓曲线的半高全宽分析，可测量直径在1.78毫米至4.14毫米之间的充满造影剂的有机玻璃圆柱体的直径，平均误差在2%以内。本文还提供了这种电影视频密度测定分析方法的理论基础。
