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 detect a series of positions of a catheter inserted into the biological tissue from data obtained in time series by a sensor observing the surrounding of a lumen of the biological tissue while moving in the lumen, and to switch a display mode between a first mode for displaying a first figure representing the series of positions in the three-dimensional image, and a second mode for displaying a second figure representing one position among the series of positions in the three-dimensional image.

A diagnostic assistance device is a diagnostic assistance device configured to generate three-dimensional data of a biological tissue based on tomographic data of the biological tissue, and display the generated three-dimensional data as a three-dimensional image on a display. The diagnostic assistance device includes a control unit configured to adjust a color tone of each voxel of the three-dimensional image according to a distance from a reference point, a reference line, or a reference plane in a three-dimensional space to each point of the three-dimensional data.

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.

Diagnosis support device, diagnosis support system, and diagnosis support method

An imaging device capable of acquiring images of an internal structure of a living body highly accurately in a wide range. An imaging device has a first housing to which a proximal portion of an outer sheath is fixed, with a drive shaft for driving a imaging unit and an inner sheath extending through the first housing, and a second housing to which a proximal portion of the inner sheath is fixed and which holds the drive shaft rotatably therein. The first housing has a first port held in fluid communication with an inner lumen of the outer sheath, and the second housing is movable toward and away from the first housing. The imaging device also includes a first gap between the inner sheath and the outer sheath and a second gap between the inner sheath and the drive shaft.

Imaging device

An image processing device includes a drive unit connected with an ultrasound element or an image sensor element, and an image processing unit that sequentially generates two-dimensional images of an organ, a blood vessel, or a medical instrument, based on information which is acquired by the ultrasound element or the image sensor element, and that generates a three-dimensional image based on the two-dimensional image. The image processing unit includes a storage unit that stores position correspondence information and/or image correspondence information, and a control unit that determines a position inside the three-dimensional image corresponding to a current position of the ultrasound element or the image sensor element, based on the position correspondence information or the image correspondence information, and that generates display information in real time, in which the determined position inside the three-dimensional image is identified and displayed inside the three-dimensional image.

Image processing device and image display method

A contrast agent removing device configured to remove a contrast agent from blood vessels includes: an elongated outer tube; an inner tubearranged in an interior of the outer tube; an expandable portioninterlocked with a distal portion of the inner tubeand configured to be capable of being stored within the outer tubeand to expand radially outward in a funnel shape opening in a distal direction by projecting from the outer tube in the distal direction; and a fixing portionprovided at the rim of the expandable portionand configured to be capable of being fixed to a contact object.
