Three dimensional echocardiography offers the benefit of non-invasive measurement of chamber volume at the cost of increased effort of data handling. Automated or semi-automated image analysis may help to reduce manual effort but can embody assumptions and limitations which have a significant effect on results.
Manual measurement of left ventricular volume from 3D echocardiographs is time consuming, and there is a clinical need for automatic methods. We describe a semiautomatic method which uses a 3D image gradient operator and a short-axis boundary detector. Six patients with cardiomyopathy were studied using 3D echocardiography and the images were analysed to measure the repeatability of measurement by...
