Embodiment Construction

[0021] figure 2 show figure 1 Examples of the image, but it is avoided figure 1 The treatment of the 赝 中 中 中 is created by curve reconstruction.The noise of the intervention in the ventricular intervention is rejected, and the ash from the use of unobstructed blood vessels is used.Arrow indication and figure 1 The same position.To obtain this result, check the location of the element used in projection.Novice (Novice) or simple means is to check each point along the path between the nearest and the farthest point to determine whether the point is inside the tubular tree structure.The points that are not located in the pipe structure are excluded from the combination or algebraic calculation of the pixel gray of the projection.The calculation time of the inspection may be excessively long and delayed, and it may not be fast enough for the interaction rate.

Abstract

Various improvements may lead to reducing or avoiding artifacts in curved planar reformation imaging. The source of voxels used in projection rendering (32) may be verified (34) to be from the vessels rather than intervening anatomy. To make the check more rapid, a hierarchal data structure may be used. Rather than using the vessels, geometric forms fit (24) to the vessels may be used. Processing with geometric forms (22) may be more rapid than a fine mesh or surface. Since tubular structures have a predictable change over length, the geometric forms or the vessel data itself may be filtered (26) with a monotonicity constraint. Instead of using planes for segments based on the lumen or center line, a convex hull around the tubular structures is formed (28) for the curved planar reformation.

Description

[0001] Relevant application [0002] This patent document requires the submitted date of the submission date under 35 U.S.C. §119 (E), which is submitted by the temporary US patent application number NO. 61 / 757,918, which is submitted on January 29, 2013, where it is incorporated through reference. Background technique [0003] The examples of this embodiment involve medical imaging and specific, involve curve reconstruction. [0004] A computer fault scanning (CT) and / or magnetic resonance imaging (MRI) can be used to simply imagine the vascular system.CT and MRI provide high -resolution volume information to see the anatomical objects (such as the ventricular and blood vessels).CT can be used in conjunction with the "Live" Modality of Fluoroscopy to use CT.For these types of imaging, the projection images during the process are public.CT and MRI data usually contain too much information, so the choice of some information used for display during the "live" process is valuable.
