Abstract

A system and method for modifying a curved cut plane of a 3D volume to locate objects or sections of interest within the 3D volume intersected by the cut plane. A cross-section of the 3D volume along an initially estimated curved cut plane is projected onto a flat viewing plane, and a panorama image of the cross-section is displayed to the user. If the initially estimated curved cut plane does not exactly intersect the object or section of interest, the user manipulates a user input device to modify the curve of the plane inward or outward in the 3D volume away from the projected plane. As the user manipulates the user input device, an affected portion of the curve is recalculated and a modified curved cut plane is reconstructed based on the recalculated curve for re-projecting a modified cross-section of the 3D volume in real time with the movement of the user input device. The user is therefore provided with instant visual feedback as the user moves the user input device to browse in and out within the 3D volume from the current projected plane.
