Abstract
An intravascular imaging system can include a catheter, a position sensor, and an intravascular imaging engine for receiving information from the catheter and the position sensor. The position sensor can include a reference element and a movable element, which can have a movable element position that is correlated to the position of an imaging transducer in the catheter. The relative position between the movable element and a reference element can be determined and can correspond to the relative movement of the transducer within a patient's vasculature. The imaging engine can receive position information from the position sensor and image information from the catheter and generate a display using the received information. Because relative movement of the transducer can be determined, spatial relationships between sets of imaging data can be determined, and image data from multiple transducer locations can be combined into one image.
