Abstract: A learning model generation method for generating a learning model that aids understanding of an image acquired with an image-acquiring catheter. The learning model generation method includes: creating a division line that divides a lumen region into a first region into which the image-acquiring catheter is inserted and a second region reaching an edge of a two-dimensional image, when it is determined that the lumen region reaches an edge of the two-dimensional image; creating second classification data in which a probability of being the lumen region and a probability of being an extra-luminal region are allocated; recording the two-dimensional image associated with the second classification data in a training database; and generating a learning model that outputs third classification data in which an input two-dimensional image is classified into a plurality of regions including a living tissue region, the lumen region, and an extra-luminal region, by machine learning.

Abstract: 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.
