  • Publication number: 20250095145
    Abstract: In the endoscopic examination support apparatus, the image acquisition means acquires an endoscopic image taken by an endoscope. The first lesion detection means detects a lesion candidate from the endoscopic image, using a machine learning model that learned a relationship between the lesion candidate and a normal state of a large intestine. The second lesion detection means detects a lesion candidate from the endoscopic image, using a machine learning model that learned a relationship between the lesion candidate and a predetermined state of the large intestine. The output means outputs at least one of a detection result of the first lesion detection means and a detection result of the second lesion detection means.

  • Publication number: 20240382065
    Abstract: An information processing apparatus (2000) detects an abnormal region (30) in each of a plurality of video frames (14) constituting video data (12) in which the inside of a body is captured. The information processing apparatus (2000) outputs output information related to the detected abnormal region (30). Herein, the information processing apparatus (2000) starts outputting of the output information when a detection score based on a proportion of the number of the video frames (14) in which the abnormal region (30) is detected becomes equal to or more than a first threshold value in a state where outputting of the output information is not being performed. Further, the information processing apparatus (2000) ends outputting of the output information when the detection score becomes equal to or less than a second threshold value in a state where outputting of the output information is being performed.

The genetic mutation information (30) indicates information regarding a genetic mutation in a deoxyribonucleic acid (DNA) sequence of a target cell (20) obtained from a target organism (10). In the position information (40), a position on the DNA sequence is associated with the type of a cell or the type of an organ. The genetic characteristic estimation device (2000) determines a genetic mutation at the position associated with the type of the target cell (20) or the type of an organ including the target cell (20) in the position information (40) from among genetic mutations indicated by the genetic mutation information (30), and computes a genetic characteristic index value representing a genetic characteristic of the target organism (10) based on a characteristic of the determined genetic mutation.
