为了评价市售超声扫描仪的扩展视野（FOV）软件获得的距离测量的准确性，使用了两个定制设计的体模，允许扫描平面和曲面。由三名检查员使用各种传感器对幻影中的各种已知距离进行了540次测量。尽管在操作员和探头之间观察到微小差异，但99.4%（537/540）的距离测量值准确度在± 4%范围内。这种扩展FOV技术可在体外对大型物体进行精确测量。
To evaluate the accuracy of distance measurements obtained with the extended-field-of-view (FOV) software of a commercially available ultrasonographic scanner, two custom-designed phantoms that allowed scanning of flat and curved surfaces were used. Five hundred forty measurements of various known distances in the phantoms were made by three examiners using various transducers. Although minor differences were observed between operators and transducers, 99.4% (537 of 540) of the distance measurements were accurate within plus or minus 4%. This extended-FOV technology provides accurate measurements of large objects in vitro.
