Abstract
An ultrasonic diagnostic imaging system has an array probe for acquiring a 3D image dataset of a subject. Volume rendering is performed to produce a volume image of the subject, and MPR reconstruction is performed to produce three orthogonal 2D images of the subject. The point of intersection of the three 2D image planes is locationally marked by a crosshair or other graphic in each 2D image. The corresponding location in the volume image is marked with a virtual light source which illuminates the interior of the 3D volume and is positionally linked to the location markers in the MPR images.
