| abstract |
A method for generating a medical result image (RESI) using a current image (CI), a target image (TI) and a reference image (REFI). All images depict at least partially the same body region of a patient (6). The method comprises the following steps: i. defining (S13; S23) at least one image segment (ISEG) within the target image, ii. registering (S14; S24) the reference image with the target image by establishing a registration matrix (REGMA) for each image segment within the target image, wherein the registration matrix is specific for the respective image segment, iii. detecting (S16; S26) a position of a surgical instrument (IPOS) in the current image, the position corresponding to an image segment of the target image, and iv. generating (S17; S27) the medical result image by fusing the current image and the reference image using the registration matrix as signed to the image segment according to the position of the surgical instrument within the current image. A computing unit thereof, a medical imaging apparatus comprising such unit and computer program product, computer readable medium executing such method are also provided. |
