摘要:
An automated medical system comprises a first instrument assembly including a first ultrasound transducer having a first transducer field of view that transmits and receives ultrasound signals in imaging planes disposed circumferentially about a guide instrument, and a second instrument assembly including a second ultrasound transducer having a second transducer field of view coupled to one of a second flexible guide instrument and a working instrument. A computing system is operatively coupled to the respective first and second transducers and configured to determine a relative spatial orientation of the respective first and second transducers based at least in part on detecting a signal transmitted by one of the first and second transducers and received by the other of the first and second transducers, the received signal having an amplitude indicating the receiving one of the transducers is in the field of view of the transmitting one of the transducers.
