Publication number: 20230248441Abstract: Techniques are disclosed for extended-reality (XR) visualization of a flexible medical tool. In one example, sensor(s), disposed near a distal portion of a flexible shaft of a medical tool configured for insertion into a patient, sense values indicative of a pose of the medical tool with respect to an EM field. A computing device adjusts, based on the sensed values, a relative alignment between the medical tool, an internal anatomy of the patient, and an exterior of the body of the patient. The computing device generates, based on the computed relative alignment between the medical tool, the internal anatomy, and the exterior of the body, XR content comprising a visual representation of the medical tool within the patients internal anatomy, and outputs the XR content for display to a user so as to simulate a current pose of the medical tool relative to the body of the patient.Type: ApplicationFiled: June 29, 2021Publication date: August 10, 2023Inventors: Enio T. Perez Filho, Braden Eliason, Reza Talaie, Aaron Koenigsberg, Jafar Golzarian
