Abstract: An image processing device includes a control unit configured to determine, when an input is received of at least one cross-sectional image obtained using a sensor configured to move in a lumen of a biological tissue, whether a deformation spot that is on an inner surface of the biological tissue and that has been deformed by pressing an elongated medical device inserted into the lumen is included in the at least one cross-sectional image, and specify a position of the medical device based on a position of the deformation spot when it is determined that the deformation spot is included in the at least one cross-sectional image.

Abstract: An ultrasound catheter capable of reducing noise in an ultrasound image by limiting reflection of ultrasound oscillated from a distal end side surface of a transducer. The ultrasound catheter includes: an elongated sheath; an ultrasound transducer; a shaft that supports the ultrasound transducer; and a cap that seals an opening portion of the sheath and has an X-ray opaque property. The cap includes an extension portion including a proximal portion facing the ultrasound transducer and an outer circumferential surface facing an inner circumferential surface of the sheath. The proximal portion includes an ultrasound scattering surface that scatters ultrasound from the ultrasound transducer. The outer circumferential surface includes a contact portion that is in contact with the inner circumferential surface of the sheath in a liquid-tight manner. The ultrasound scattering surface intersects with a virtual plane obtained by enlarging the ultrasound oscillation surface in an in-plane direction.

Abstract: An image processing device is an image processing device configured to cause a display to display three-dimensional data as a three-dimensional image, the three-dimensional data representing a biological tissue. The image processing device includes: a control unit configured to adjust a color tone of each pixel of the three-dimensional image according to a dimension of the biological tissue in a linear direction from a viewpoint when the three-dimensional image is displayed on the display.

Abstract: An ultrasound catheter and an ultrasound catheter system that can acquire an image of an observation target with high accuracy when inserted into a large inner lumen. An ultrasound catheter includes: an outer sheath having an accommodation lumen; an inner sheath that can move along an axis; a drive shaft that can rotate in the inner sheath and the outer sheath; and a transducer that is disposed in the accommodation lumen and fixed to a distal end of the drive shaft. The outer sheath includes a first bent portion bent and shaped in advance at a predetermined angle on a proximal side of a most distal end of the accommodation lumen, and a first tubular portion and a second tubular portion positioned on a distal side of the first bent portion and on the proximal side of the most distal end of the accommodation lumen.

Abstract: A diagnosis support device includes a control unit that correlates a plurality of pixels included in a two-dimensional image with two or more classes including a biological tissue class, the two-dimensional image being generated by using a signal of a reflected wave of ultrasound transmitted inside a biological tissue through which blood passes and the two-dimensional image including the biological tissue, generates a three-dimensional image of the biological tissue from a pixel group correlated with the biological tissue class, and performs control of displaying the generated three-dimensional image of the biological tissue.
