摘要：

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.
