摘要： An image processing device includes: a control unit configured to acquire a cross-sectional image obtained using a sensor configured to move in a lumen of a biological tissue for each position in a movement direction of the sensor, analyze the acquired cross-sectional image to calculate a centroid position of a cross section of the lumen in the cross-sectional image, and execute smoothing on a calculation result obtained for a plurality of positions in the movement direction of the sensor, and evaluate a difference between the calculated centroid position and a centroid position obtained as a result of the smoothing for each position in the movement direction of the sensor, thereby deriving a pulsation score representing expansion and contraction of the lumen in the acquired cross-sectional image by a numerical value.

摘要： An information processing device that assists understanding of an image acquired by an image acquisition catheter. The information processing device includes: an image acquisition unit that acquires a catheter image including an inner cavity obtained by an image acquisition catheter; a position information acquisition unit that acquires position information regarding a position of a medical instrument inserted into the inner cavity included in the catheter image; and a first data output unit that inputs the acquired catheter image and the acquired position information to a first trained model that, upon receiving input of the catheter image and the position information, outputs first data in which each region of the catheter image is classified into at least three of a biological tissue region, a medical instrument region where the medical instrument exists, and a non-biological tissue region, and outputs the first data.

摘要： 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.
