Stent Visualization and Malapposition Detection Systems, Devices, and Methods

摘要

In part, the invention relates to computer-based methods, devices, and systems suitable for displaying stent malapposition in a 2-D or 3-D image. A threshold malapposition distance can be set as an input in response to which a software component in an imaging pipeline automatically detects stent struts and calculates a malapposition distance from a lumen contour. Projections of stent strut dimensions can be used to compensate for stent imaging artifacts results from imaging probe orientation in the lumen.

1. A method of detecting stent malapposition in a blood vessel comprising:
storing, in one or more memory devices, a stent malapposition threshold; storing, in one or more memory devices, a plurality of cross-sectional images of the blood vessel; detecting one or more stent struts in the plurality of cross-sectional images using a stent detection image data processing module; detecting a boundary of a lumen of the blood vessel by processing the image data using a lumen detection image data processing module; measuring a stent malapposition distance with respect to one or more stent struts using a stent malapposition detection image data processing module; comparing one or more stent malapposition distance; and displaying one or more indicia corresponding.
