A high speed method for presenting display of images obtained from a volumetric scanner in which multiple slices of object space are displayed simultaneously in real time thereby enabling a viewer to study relationships between various parts of the object. The slices are selectable by the viewer manipulating an icon on the display screen. Accordingly C-scans or B scans may be selected as well as I scans in which the scan plane has a selected orientation. Multiple I scans may be selected and viewed in perspective so that the viewer has an impression of a three dimensional display. Color and spectral doppler is incorporated with the scans to provide additional information of dynamic properties.
