Accuracy and Repeatability of Bladder Volume Measurement Using Ultrasonic Imaging

Abstract

We assessed 6 methods for calculating bladder volume from ultrasonic cross-sectional scans. The technique that used the largest number of features from the scans gave the best results. For volumes greater than 150 ml. an accuracy of 0.87 and repeatability of .+-. 9 per cent (standard deviation) were obtained.
