Apparatus for, and method of, processing volumetric medical image data

摘要

Apparatus for performing an imaging procedure comprising processing volumetric image data comprising an image processing unit configured to obtain first image data representative of a region including at least one vessel and at least one associated feature, and second image data representative of at least part of the region, an image refinement unit configured to process the first image data and the second image data to produce a combined image representative of the at least one vessel, wherein the associated feature is removed or reduced in intensity in the combined image, and a rendering unit configured to render the combined image as a simulated view that simulates a view obtainable from an alternative imaging procedure.

1. An apparatus for performing an imaging procedure including processing volumetric medical image data, the apparatus comprising:
an image processing unit configured to obtain first non-contrast-enhanced medical image data representative of a region including at least one vessel and at least one associated feature, and second contrast-enhanced medical image data representative of at least part of the region and set the region on the first non-contrast-enhanced medical image data and the second contrast-enhanced medical image data, wherein the first non-contrast-enhanced medical image data comprises one of CT data, cone-beam CT data, and MR data, and the second contrast-enhanced medical image data comprises one of CT data, cone-beam CT data, and MR data such that the first non-contrast-enhanced medical image data and the second contrast-enhanced medical image data both comprise CT data or both comprise cone-beam CT data or both comprise MR data, and wherein neither the first non-contrast-enhanced medical image data nor the second contrast-enhanced medical image data comprises data obtained by catheter coronary angiography; an image refinement unit configured to execute a local registration between the first non-contrast-enhanced medical image data and the second contrast-enhanced medical image data based on the set region and subtract the second contrast-enhanced medical image data from the first non-contrast-enhanced medical image data to produce a combined image representative of the at least one vessel, wherein the associated feature is removed or reduced in intensity in the combined image; and a rendering unit configured to render the combined image as a simulated catheter coronary angiogram view without using data obtained by catheter coronary angiography.
