In Vitro Measurement Accuracy of Three‐Dimensional Ultrasound

Echocardiography, 2001
Objectives: We sought to validate distance and volume measurements in three‐dimensional (3‐D) ultrasound images. Background: Even with the latest equipment, it is not known how accurate 3‐D echocardiographic measurements are. Methods: Six models were imaged in ethanol solution and two within a tissue phantom using a mechanical rotation device rotating ...
