Abstract
In part, the disclosure relates to methods of guidewire detection in intravascular data sets such as scan lines, frames, images and combinations thereof. Methods of generating one or more indicia of a guidewire in a representation of blood vessel are also features of the disclosure. A carpet view is generated in one embodiment and regions of relatively higher contrast are detected as candidate guidewire regions. In one embodiment, the disclosure relates to selective removal of guidewire segments from a set of intravascular data and the display of a representation of a blood vessel via a user interface. Representations of a guidewire can be toggled on and off in one embodiment.
