| 摘要 |
The invention relates to a method for the joint of registering, archiving, contrast-retaining merging, and visualizing of 2D x-ray images and reconstructed 2D projections or 3D views of generated image data in minimally invasive medical interventions or operations performed under x-ray control on internal organs, areas of tissue, lesions, or pathological structures in a patient's body. A first image and the image data of a second image being mixed over the first image are mutually linked, co-registered, and merged using an alpha-channel-based mixing technique, whereby the color values or gray-scale values of the individual pixels of the first image are prior to being mixed-over with the segmented foreground of the second image brightened through the application of a color-value or gray-scale-value for compensating or lessening the reduction in contrast that occurs during mix-over in the first image before being displayed graphically on a monitor terminal. |
