With the proliferation of portable sonography and the increase in nontraditional users, there is an increased need for automated decision support to standardize results. We developed algorithms to evaluate the presence or absence of "B-lines" on thoracic sonography as a marker for interstitial fluid. Algorithm performance was compared against an average of scores from 2 expert clinical sonographers. On the set for algorithm development, 90% of the scores matched the average expert scores with differences of 1 or less. On the independent set, a perfect match was achieved. We believe that these are the first reported results in computerized B-line scoring.
随着便携式超声技术的普及和非传统使用者的增加，人们越来越需要自动化决策支持来规范结果。我们开发了算法来评估胸部超声中“B 线”的存在或缺失情况，作为间质液的标志物。算法性能与 2 位专家临床超声医师的平均评分进行了比较。在算法开发的数据集上，90%的评分与专家评分相差 1 分或以内。在独立数据集上，实现了完美匹配。我们相信这是计算机化 B 线评分的首批报告结果。
