Abstract
Blood vessel diameter measurement is crucial to volume flow measurement in medical ultrasound. The accuracy of the measurement is examined in this study. Experiments were made on three kinds of tube using four transducers on three commercial duplex ultrasound scanners. The accuracy of the inner diameter measurement is affected by ultrasonic pulse length. By correcting this effect, it has been shown that the accuracy of the measurement can be increased significantly over a range of conditions.
