1. An intravascular system comprising: (a) an intravascular imaging catheter including a proximal end and a distal end, along with a transducer located in a transducer position near the distal end; (b) a position sensor including a movable element and a reference element, the movable element having a movable element position that is correlated to the transducer position, the position sensor being configured to measure the movable element position relative to a position of the reference element; (c) an intravascular imaging engine coupled to the intravascular imaging catheter, the intravascular imaging engine being configured to receive image information from the intravascular imaging catheter and position information from the position sensor and to generate a display based on the image information and the position information.
