1. A method of visualizing three-dimensional (3D) ultrasound data, the method comprising: acquiring image slices from a volumetric image data set; generating a ray profile using one or more rays through at least one of the image slices, the one or more rays extending along a depth of the volumetric image data set; identifying one or more seed points along the one or more rays based on the ray profile; identifying one or more anchor points located a defined distance relative to the one or more seed points; defining a clipping surface using the one or more anchor points, the clipping surface defining a rendering region within the volumetric image data set; and rendering a 3D image of the rendering region within the volumetric image data set.
