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, a number of 2D ultrasound images of the examination region are acquired, the preoperative 3D image dataset is updated using the 2D ultrasound images, and the 3D reconstruction image is generated on the basis of the updated 3D image dataset.
Claims32
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;
- acquiring a plurality of 2D ultrasound images of said examination region contemporaneously with a medical procedure involving said examination region;
- updating the preoperatively acquired 3D image dataset using said 2D ultrasound images, thereby obtaining an updated 3D image dataset;
- and
- reconstructing a 3D reconstruction image from said updated 3D image dataset and using said 3D reconstruction image in said medical procedure.
An apparatus for three-dimensional presentation of an examination region of a patient as a 3D reconstruction image, comprising:
- an image processor containing 3D image dataset of an examination region acquired prior to conducting a medical procedure involving said examination region;
- an ultrasound image acquisition device for acquiring a plurality of 2D ultrasound images of said examination region contemporaneously with said medical procedure;
- said image processor being supplied with said 2D ultrasound images and updating the preoperatively acquired 3D image dataset using said 2D ultrasound images, thereby obtaining an updated 3D image dataset, 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.
