Abstract
Three-dimensional ultrasound is emerging as a viable resource for the imagi ng of internal organs. Quantitative studies correlating ultrasonic volume m easurements with MRI data continue to validate this modality as a more effi cient alternative for 3D imaging studies. However, the processing required to form 3D images from a set of 2D images may result in a loss of spatial r esolution and may give rise to artifacts. This paper examines a method of a utomatic feature extraction and data quantification in 3D data sets as comp ared with original 2D data. This work will implement an active contour algo rithm to automatically extract the endocardial borders of septal defects in echocardiographic images, and compare the size of the defects in the origi nal 2D images and the 3D data sets.
