Abstract
In part, the disclosure relates to methods of stent strut detection relative to a side branch region using intravascular data. In one embodiment, detecting stent struts relative to jailed side branches is performed using a scan line-based peak analysis. In one embodiment, false positive determinations relating to stent struts are analyzed using a model strut.
Claims20
-20. (canceled)
A method of detecting one or more stent struts disposed in a side branch, the method comprising:
- storing, in memory accessible by a diagnostic system, one or more image datasets obtained with respect to a blood vessel;
- detecting, using a side branch detection module of the diagnostic system, one or more side branches of the blood vessel using the one or more image datasets;
- identifying side branch image data corresponding to each detected side branch, wherein each side branch has a shadow region;
- determining one or more candidate intensity peaks relative to one or more shadow regions;
- and
- validating the one or more candidate intensity peaks, wherein each valid intensity peak corresponds to a portion of a stent strut jailing one or more side branches.
3 more elements
An automatic processor-based diagnostic system for detecting one or more stent struts disposed in a side branch, the system comprising:
- one or more memory devices;
- and
- a computing device in communication with the memory device, wherein the memory device comprises instructions executable by the computing device to cause the computing device to:
- store, in the one or more memory devices, one or more image datasets obtained with respect to a blood vessel;
- detect, using a side branch detection module of the diagnostic system, one or more side branches of the blood vessel using the one or more image datasets;
- identify side branch image data corresponding to each detected side branch, wherein each side branch has a shadow region;
- determine one or more candidate intensity peaks relative to one or more shadow regions;
- and
- validate the one or more candidate intensity peaks, wherein each valid intensity peak corresponds to a portion of a stent strut jailing one or more side branches.
