Embodiment Construction

[0032] exist figure 1 The method according to the invention is shown by way of example in the schematic illustration of . According to the method, in method step 1 , the patient is initially scanned in rotation by means of a CTA system, for example by means of a C-arm device, usually while administering a contrast medium. In principle, it should be pointed out here that it is sufficient for the method according to the invention to provide raw data or completed volume data acquired during such a scan. In a next method step 2, a reconstruction R of the region or volume of interest is performed from the measured absorption values ​​of the scan. All methods of the prior art can be used here. In method step 3 , a three-dimensional CT representation is calculated from the resulting volume data record and stored, if necessary, in a memory. On the one hand, this reconstructed data set can then be used further and / or can be sent to other locations and users, who respectively check t...

Abstract

A method is disclosed for highlighting local characteristics in anatomical volume renderings of vessel structures and a computer system is disclosed for carrying out this method. In at least one embodiment of the method, the method includes determining or receiving a volume of interest; generating or receiving at least one first tomographic volume data record in the volume of interest, having a rendered display of a vessel structure; generating or receiving at least one second volume data record, which is used as a mask for the first volume data record and has at least one characteristic vector with a minimum data width of 2 bit for each voxel; accepting at least one characteristic definition for at least one predefined position or predefined region of the mask or the first volume data record, which is at the same position, and encoding the at least one characteristic definition in at least one characteristic vector of the mask; and combined rendering of the first volume data record and the mask, wherein the mask translucently marks a defined surrounding area of the predefined position as a function of the characteristic vectors present there.

Description

technical field [0001] The present invention relates to a method for emphasizing local features in anatomical volume illustrations of vascular structures, wherein in a volume of interest (Volume of Interest = VOI) feature definitions should be emphasized, e.g. manually or automatically collected for a certain area of ​​the map The results of the inspection and should show feature definitions by providing additional information. Background technique [0002] Due to the increasing specialization of diagnostic techniques and the resulting spatially dispersed examinations, it is increasingly necessary to provide diagnostic and therapeutic practitioners with diagnostic information found in different locations. Basically, this has hitherto been done by describing the findings in a written text, where the individual attending physicians involved have to finally read all relevant and irrelevant findings and grade them according to their importance, and finally have to be read by Di...
