Abstract: A diagnosis assistance device includes a control unit that generates line data indicating an intensity value of a reflected wave from an object, which is present in a transmission direction of ultrasound, for each combination of a movement position of an ultrasound transducer that radially transmits the ultrasound while being moved inside a biological tissue and the transmission direction of the ultrasound with reference to an observation result of a cross section of the biological tissue by the ultrasound transducer and generates a detection image which includes pixels corresponding to the generated line data and in which pixels corresponding to the line data at the same movement position are arranged in one direction. Pixels corresponding to the line data in the same transmission direction are arranged in a direction perpendicular to the one direction, and each pixel value is set according to an abnormality degree of the generated line data.

Abstract: An information processing device including: a control unit configured to: acquire at least one frame image generated by using line data indicating intensity of a reflection wave with respect to an ultrasound radially transmitted from an ultrasound transducer moving inside a biological tissue, and extract a specific region from the at least one frame image based on a ratio between an average of luminance in a region of interest included in the at least one frame image and a dispersion of luminance in the region of interest.

Abstract: In an imaging system, vascular tomographic images and vascular fluoroscopic images which each include a plurality of frames are collected. A position of an image of the probe included in each of the frames of the fluoroscopic images is acquired. The frame of the fluoroscopic image and the frame of the tomographic image which is taken at substantially the same time as the frame of the fluoroscopic image are displayed at the same time. A position of a blood vessel designated by a user is acquired from the displayed frame of the fluoroscopic image. The frame of the fluoroscopic image which includes the image of the probe at a position closer to the position of the blood vessel designated by the user is displayed at the same time as the frame of the tomographic image which is taken at substantially the same time as the frame of the fluoroscopic image.

Abstract: In an imaging system, a vascular image extending along a vascular length direction, which is obtained from multiple transverse cross-sectional images of a blood vessel imaged by inserting a probe into the blood vessel, and multiple fluoroscopic images of the blood vessel imaged while the probe is inserted into the blood vessel are collected. A first position and a second position along the vascular length direction, which are designated by a user on the displayed vascular image, are acquired. The vascular image and the fluoroscopic image indicating the first position and the second position are displayed.
