Three‐dimensional ultrasound: accuracy of distance and volume measurements [PDF]

open access: bronzeUltrasound in Obstetrics & Gynecology, 1996
AbstractThe aim of this study was to evaluate the accuracy of three‐dimensional ultrasound distance and volume measurements using a commercially available three‐dimensional ultrasound scanner. Sixty‐two distance measurements were performed twice on an ultrasound tissue‐mimicking phantom located in a water bath.
