Image processing, image visualization and image archiving system for the contra-merging and visualization of coregistered image data

摘要

The present invention relates to an image processing, image visualization and image archiving system which can be used in particular in the field of diagnostic and interventional radiology and to a method for joint registration, archiving, contrast-preserving fusion and visualization of 2-D fluoroscopic images (F) performed by this system. and reconstructed 2-D projections or 3-D views (M) of generated image data, which are required, for example, in the context of minimally invasive interventions or surgical interventions, which are under fluoroscopic control of internal organs, tissue areas, lesions or pathological structures in the interior of the body a patient. According to this method, the image data of a first image to be blended (F) and the image data of a second image (M) blending the first image (F) are rendered using an alpha channel based blending technique in which the gray levels of the individual pixels of the first image (F) before crossfading with the segmented foreground (MV) of the second image (M) by exposure to a gray-level term which compensates or attenuates the contrasting image of the first image (F) to be blended during the cross-fade, is linked to one another, coregistered and merge contra-fused before appearing on the display screen (AB) of a screen terminal in graphical form.
