Abstract
A method, an imaging apparatus and a computer readable medium are enabled for automatically registering medical images. The imaging apparatus may be an amended C-arm. The image acquisition apparatus has a primary x-ray source and at least one auxiliary x-ray source, a detector for receiving radiation of the primary and auxiliary x-ray source, and an interface to a registration unit. The registration unit computes a 3D/2D registration of a provided 3D image and at least two acquired 2D images. An output interface is configured to provide an output and to display the registered images on a monitor.
Claims15
A method for automatically registering medical images, the method comprising the following steps:
- providing a 3D image;
- acquiring at least two 2D images on an acquisition device having a primary x-ray source and at least one auxiliary x-ray source and one common detector for the primary and auxiliary x-ray sources, and having an angular separation of about 15-20 degrees between the primary and auxiliary x-ray sources;
- computing a 3D/2D registration of the 3D image and the acquired 2D images;
- and
- outputting a result of the computed 3D/2D registration.
