  • Publication number: 20210378632
    Abstract: In a transcatheter treatment support technique using a combination of a guide wire equipped with a photoacoustic technique and an ultrasonic imaging device, the ultrasonic imaging device estimates a front edge position of the guide wire using a difference between arrival times of photoacoustic waves arriving at an array of elements configuring an ultrasonic probe or a change of an image of the photoacoustic generation source, which depends on a distance of the photoacoustic generation source from an imaging region, and grasps a relationship between an imaging position and the front edge position of the guide wire using the estimation result. This enables visually grasping a relationship between a region (imaging region) from which an image is able to be obtained with reflective waves from a biological body with use of the ultrasonic probe and an insertion object present outside the region, particularly, the front edge of the guide wire.
