Patent ID: 8364239

Claim:
A method for providing information of a locally resolved reconstruction quality of a target volume comprising a subarea in a three-dimensional reconstruction volume presentation, comprising: recording a first image of the target volume by an imaging recording device disposed within the target volume, which is in a body of a subject undergoing a medical examination; creating a three-dimensional reconstruction volume presentation from a plurality of images acquired by the imaging recording device, prerecorded by way of another imaging modality or both, wherein the first image and the three-dimensional reconstruction volume are spatially registered relative to one another; determining spatial imaging-coverage in the three-dimensional reconstruction volume of at least a portion of the target volume, the spatial imaging-coverage indicative of at least an area of the target volume not recorded by the imaging recording device in the first image of the target volume; wherein the spatial imaging coverage volume is created with a dimension of the three- dimensional reconstruction volume, wherein a voxel of the coverage volume is assigned to a voxel of the three-dimensional reconstruction volume, wherein the voxel of the coverage volume is assigned a value indicating reconstruction quality depending on the imaging-coverage determination, and wherein the coverage volume is presented at least partly with the three-dimensional reconstruction volume presentation based on the assigned value; wherein the assigned value is a grayscale value described by a function, wherein a maximum grayscale value of the function lying in the voxel is assigned to the voxel; creating the information of the locally resolved reconstruction quality of the three-dimensional reconstruction volume based on the determining of the spatial imaging-coverage; outputting the information of the reconstruction quality of the three-dimensional reconstruction volume; and based on the information of the reconstruction quality, repositioning in real-time the imaging recording device within the target volume to record at least a further image of the target volume to record said at least area of the target volume not previously recorded by the imaging recording device.
