Patent ID: 8077940

Claim:
A method for reconstructing a three-dimensional image of a target volume of a human body in realtime during a medical procedure, comprising: recording a plurality of two-dimensional images of the target volume by an image recording device; selecting a basic set from the recorded images comprising a minimum number of two-dimensional images; determining the three-dimensional reconstruction volume from the basic set; recording a new image of the target volume by the image recording device; locally limited updating a partial area of the reconstruction volume covered by the new image under a condition; and displaying the updated reconstruction volume, wherein the recorded images are filed in a memory, wherein the images are filed in the memory in an order according to a recording time, wherein a size of the memory is adjusted, wherein a defined subset of the filed images is selected as the basic set, wherein each recorded image comprises an assigned information that comprises a voxel of the reconstruction volume to which the image has contributed, and wherein a threshold is defined for the voxel to which the image has contributed and the image is deleted from the basic set or the memory if the threshold is undershot.
