Catheter system

Abstract

One aspect of a catheter system includes a reference portion and a moving portion. The moving portion is movable along the reference portion in a longitudinal direction of the reference portion. The moving portion includes a wave transceiver unit that transmits/receives one or more types of waves. The wave transceiver unit transmits a first type of waves among the one or more types of waves in a direction intersecting with the longitudinal direction in a space inside a target object and receives the first type of waves reflected from the target object. The reference portion includes a reference region. In the reference region, one or more types of elements are located in the longitudinal direction based on a predetermined rule so that the state of reflection of a second type of waves included in the one or more types of waves varies in the longitudinal direction.
