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.

Claim (Index 37):
A programmable processor-based computing device of a diagnostic system for detecting one or more guidewires disposed in a blood vessel, the programmable processor-based computing device comprising:\n one or more data access channels to receive one or more image datasets; a processor and associated memory in electrical communication with the one or more data access channels, wherein the processor is programmed to: store one or more image datasets of the blood vessel; detect a plurality of shadows in the one or more image datasets of the blood vessel evaluate the plurality of shadows to identify candidate guidewire shadows; validate the candidate guidewire shadows to identify a plurality of candidate guidewire detections; detect spurious guidewire segments; remove spurious guidewire segments from the plurality of candidate guidewire segments to generate a set of detected guidewire segments; and link guidewire segments from the set of detected guidewire segments to generate one or more guidewire representations.
