Detecting and displaying stent expansion

An information processing apparatus for processing an intravascular image including a plurality of image frames acquired during a pullback of an imaging catheter inserted into a vessel, the method comprising:

• a memory;
• a processor in communication with the memory to execute the following:
• displaying on a graphical user interface (GUI) an image including detected results of lumen borders and at least one stent, the image including an evaluated stent expansion and an evaluated stent apposition determined from the intravascular image;
• determining whether a modification to the detected results of the stent has been received by the GUI;
• re-evaluating stent length, stent expansion and stent apposition when it is determined that the detected results of the stent has been modified via the GUI;
• and
• displaying the re-evaluated stent expansion and the re-evaluated stent apposition on the GUI.

A non-transitory computer-readable storage medium storing a computer-readable program for causing a computer to execute a method for processing an intravascular image including a plurality of image frames acquired during a pullback of an imaging catheter inserted into a vessel, the method comprising:

• displaying on a graphical user interface (GUI) an image including detected results of lumen borders and at least one stent, the image including an evaluated stent expansion and an evaluated stent apposition determined from the intravascular image;
• determining whether a modification to the detected results of the stent has been received by the GUI;
• re-evaluating stent length, stent expansion and stent apposition when it is determined that the detected results of the stent has been modified via the GUI;
• and
• displaying the re-evaluated stent expansion and the re-evaluated stent apposition on the GUI.
