Method for reconstructing a three-dimensional target volume in realtime and displaying it
First Claim
1. 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, andwherein 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.

Abstract
The invention relates to a method for reconstructing a three-dimensional target volume, particularly within the human body, in realtime and displaying it, with a three-dimensional reconstruction volume being determined from a basic set comprising a minimum number of two-dimensional images obtained from an image recording device located within the target volume, wherein, when a new image is included in the basic set, locally limited updating at least of the reconstruction volume'"'"'s partial areas covered by the new image will under a predefined condition be performed and the updated reconstruction volume will be displayed.

17. A medical device for reconstructing a three-dimensional image of a target volume of a human body in realtime during a medical procedure, comprising:
-
an image recording device that records a plurality of two-dimensional images of the target volume; and a computing device that; selects a basic set from the recorded images comprising a minimum number of two-dimensional images, determines the three-dimensional reconstruction volume from the basic set, and locally limited updating a partial area of the reconstruction volume covered by a newly recorded image, 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.
