1. A system for performing an intravascular procedure, the system comprising:

  • a catheter configured for insertion into a blood vessel;

    an imaging device at a distal portion of the catheter and configured to capture an image of the blood vessel, the imaging device comprising an intravascular ultrasound (IVUS) transducer;

    a computer system coupled to the imaging device and having instructions to;

    receive navigation information to guide the IVUS transducer to a target site within the blood vessel;

    employ a feature detection program to automatically identify a blood vessel wall border of the blood vessel and an occlusion at the target site using data from the IVUS transducer, wherein the feature detection program comprises identifying a control point, defining an area around the control point, and moving the area to identify the blood vessel wall border and the occlusion;

    define a zone extending from the blood vessel wall border; and

    provide an operation signal to perform an operation when the catheter is outside the zone and a non-operation signal when the catheter is within the zone; and

    a control device configured to receive the operation signal and cause the catheter to perform the operation.
