摘要:
A method for registration of medical images comprises: receiving a 2D X-ray image (20) acquired with a medical 2D imaging device (14) under a first view direction; filtering the 2D X-ray image (20), such that high frequency components of the 2D X-ray image are emphasized with respect to low frequency components of the 2D X-ray image; receiving a 3D image (16) acquired with a medical 3D imaging device (12); generating a 2D projection image (26) from the 3D image, wherein the 2D projection image is generated with a second view direction; overlaying the filtered 2D X-ray image and the 2D projection image; providing functionality for changing the second view direction, such that the 2D projection image is registered with the filtered 2D X-ray image.

The present invention relates to object visualization. In order to provide a facilitated visualization of a subject's interior structure, an object visualization device (10) is provided comprising an image supply (12), a data processor (14) and an output (16). The image supply provides a 2D X-ray image of the object and also 3D data of the object. The data processor registers the 3D data to the 2D X-ray image and detects a viewing direction of the 2D X-ray image. The data processor also determines a viewing direction for a matching view of the 3D data based on the viewing direction of the 2D X-ray image. The data processor generates a pair of stereoscopic images (24) of the 3D data for the determined viewing direction and combines the 2D X-ray image with one of the images of the pair of stereoscopic images resulting in an augmented first stereoscopic image (26), whereas the other one of the pair of stereoscopic images remains as a generated second stereoscopic image (28). The output provides the augmented first stereoscopic image and the generated second stereoscopic image as an enhanced pair (30) of stereoscopic images providing an augmented 3D view of the object. Although only one of the stereoscopic images is provided with the additional X-ray image content information, in the combined view by both eyes, the X-ray information is also transferred to the other non-modified image. Thus, the X-ray information is extended into the spatial content. As an advantage, only one X-ray image is needed which means less X-ray exposure for the subject.

An apparatus (IP) and a method to generate temporally-aligned image frames for image-streams (LS, RS) in a multi-channel channel (CR, CL) imaging system (100). The apparatus (IP) allows reducing or removing temporal distance artifacts that occur when processing the frames into combined image material. The apparatus can also be used to improve signal-to-noise ratio of the frames. The multi-channel imaging system (100) may be a stereoscopic imager.
