Embodiment Construction

[0035] figure 1 A flow diagram of an embodiment of the method according to the invention is shown. In this case, the progress or success of the placement of the stent in the patient's blood vessel is to be assessed, for which in step S1 the corresponding images are taken intraoperatively or postoperatively by means of a medical imaging device, here an X-ray device with a C-arm. medical image dataset. In this case, projection images are acquired from different projection directions, and the three-dimensional medical image data set, which may be present as sectional images or slice images, is reconstructed.

[0036] figure 2 A schematic diagram of such a medical image dataset 1 is shown. Anatomical structures, such as bones 2 and rough courses 3 of blood vessels, are represented indistinctly, ie with low intensity or low image value at the corresponding image points. The metal coil 5 inserted into the aneurysm 4 can be clearly seen. Conversely, the stent 6 , which is visib...

Abstract

A method is provided for image-processing an image dataset (1) acquired from a patient by a medical imaging apparatus (9), (in particular, an X-ray apparatus), wherein the image dataset (1) includes image values associated with image points, and depicts an acquisition region of the patient containing at least one object, (in particular, a medical device (7)), to be enhanced, which is represented by image values within an image-value interval. The method includes determining a non-linearly high-pass filtered enhancement dataset, which is confined to an image portion containing image values lying in the image-value interval. The method also includes determining a result dataset (8) by adding to the image dataset (1) the enhancement dataset weighted by a weighting value. The method further includes outputting the result dataset (8).

Description

technical field [0001] The invention relates to a method for image processing of an image data record of a patient taken with a medical imaging device, in particular an x-ray device, wherein the image data record has image values ​​associated with image points and shows images with at least An enhanced recording region of an object, in particular a patient of a medical device, which is mapped by image values ​​in an image value interval. Furthermore, the invention relates to a medical imaging device, in particular an X-ray device, a computer program and an electronically readable data carrier. Background technique [0002] Medical imaging, such as X-ray imaging, and increasingly other modalities, such as magnetic resonance imaging, are used in order to be able to assess the progress and / or success of surgical procedures on patients, in particular minimally invasive procedures. During such preoperative, intraoperative, intraoperative and / or postoperative imaging, it is neces...
