1. A method for three-dimensional presentation of an examination region of a patient as a 3D reconstruction image, comprising the steps of:
- employing a preoperatively acquired 3D image dataset of an examination region of a subject that was acquired at a preoperative time preceding implementation of a medical procedure on the subject involving said examination region, said 3D image dataset representing voxels of said examination region;
with an ultrasound system, acquiring a plurality of 2D image datasets respectively representing 2D ultrasound images of said examination region contemporaneously with said medical procedure involving said examination region;
updating the preoperatively acquired 3D image dataset using said 2D image datasets representing said 2D ultrasound images to change some of said voxels of said 3D image dataset, to produce an updated 3D image dataset comprised of said preoperatively acquired 3D image dataset and the changed voxels, said updated 3D image dataset representing said examination region contemporaneously with said medical procedure; and
reconstructing a 3D reconstruction image from said updated 3D image dataset and using said 3D reconstruction image in said medical procedure.

Abstract
In a method and apparatus for the three-dimensional presentation of an examination region of a patient in the form of a 3D reconstruction image, a preoperatively acquired 3D image dataset of the examination region is employed in a medical procedure, datasets representing a number of 2D ultrasound images of the examination region are acquired, the preoperative 3D image dataset is updated using the datasets representing 2D ultrasound images, and the 3D reconstruction image is generated on the basis of the updated 3D image dataset.

17. An apparatus for three-dimensional presentation of an examination region of a patient as a 3D reconstruction image, comprising:
-
an image processor containing a 3D image dataset of an examination region of a subject that was acquired prior to conducting a medical procedure on the subject involving said examination region, said 3D image dataset representing voxels of said examination region; an ultrasound image acquisition device that acquires a plurality of 2D image datasets respectively representing plurality of 2D ultrasound images of said examination region contemporaneously with said medical procedure; said image processor supplied with said plurality of 2D image datasets representing said 2D ultrasound images that updates the preoperatively acquired 3D image dataset using said plurality of 2D image datasets representing said 2D ultrasound images to change some of said voxels of said 3D image dataset, to produce an updated 3D image dataset comprised of said preoperatively acquired 3D image dataset and the changed voxels, said updated 3D image dataset representing said examination region contemporaneously with said medical procedure, and reconstructing a 3D reconstruction image from said updated 3D image dataset; and a monitor connected to said image processor for displaying said 3D reconstruction image during said medical procedure. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
