Publication number: 20230389995Abstract: A system is for tracking includes a longitudinal element extending longitudinally from a distal tip inserted into a body to a proximal end which remains outside of the body. The element includes an IMU sensor at the tip and a series of stripes extending along the element. Data from the IMU sensor determines an angular orientation of the tip. The system also includes an exterior member positioned outside of the body. The member includes a channel extending longitudinally therethrough and a linear encoder detecting each of the stripes of the element as the element is slid through the member so that data from the encoder determines a linear displacement of the element relative to the member at a point of entry. 3D location of the tip calculated based on the determined angular orientation and the linear displacement determined at each detected stripe.Type: ApplicationFiled: April 10, 2023Publication date: December 7, 2023Inventors: Kian S.
