detecting a merkmal included in the medical image;

specifying the direction of interest on a basis of the merkmal in a case where the detected merkmal is the site of interest; and

specifying the direction of interest on a basis of a positional relationship between the merkmal and the site of interest in a case where the detected merkmal is not the site of interest.

4 . The computer-readable medium according to claim 3 , further comprising:

acquiring a second medical image including the merkmal;

specifying a positional relationship between the medical image and the second medical image on a basis of the merkmal included in the medical image and the merkmal included in the second medical image; and

specifying the direction of interest on a basis of the specified positional relationship.

5 . The computer-readable medium according to claim 1 , further comprising:

specifying the direction of interest for each of a plurality of the medical images; and

removing an outlier of the direction of interest specified on a basis of the direction of interest for each of the plurality of the medical images.

6 . The computer-readable medium according to claim 1 , further comprising:

specifying the direction of interest for each of a plurality of medical images; and

specifying the direction of interest for a medical image for which the direction of interest is not specified by performing interpolation using the specified direction of interest for each of the plurality of the medical images.

7 . The computer-readable medium according to claim 1 , further comprising:

displaying an intravascular ultrasound (IVUS) corresponding to the direction of the epicardium.

8 . An information processing method comprising:

acquiring a medical image obtained by imaging a luminal organ using a catheter;

specifying a direction of interest indicating a direction of a site of interest with respect to the medical image on a basis of the acquired medical image, wherein the direction of interest comprises specifying a direction of an epicardium; and

displaying information indicating the specified direction of interest in association with the medical image or displaying the medical image subjected to image processing on a basis of the information indicating the direction of interest.

9 . The method according to claim 8 , wherein the direction of interest is specified by inputting the acquired medical image to a learning model that outputs the direction of interest for the medical image in a case where the medical image is input.

10 . The method according to claim 8 , further comprising:

detecting a merkmal included in the medical image;

specifying the direction of interest on a basis of the merkmal in a case where the detected merkmal is the site of interest; and

specifying the direction of interest on a basis of a positional relationship between the merkmal and the site of interest in a case where the detected merkmal is not the site of interest.

11 . The method according to claim 10 , further comprising:

acquiring a second medical image including the merkmal;

specifying a positional relationship between the medical image and the second medical image on a basis of the merkmal included in the medical image and the merkmal included in the second medical image; and

specifying the direction of interest on a basis of the specified positional relationship.

12 . The method according to claim 8 , further comprising:

specifying the direction of interest for each of a plurality of the medical images; and

removing an outlier of the direction of interest specified on a basis of the direction of interest for each of the plurality of the medical images.

13 . The method according to claim 8 , further comprising:

specifying the direction of interest for each of a plurality of medical images; and

specifying the direction of interest for a medical image for which the direction of interest is not specified by performing interpolation using the specified direction of interest for each of the plurality of the medical images.

14 . An information processing device comprising:

a control unit configured to:

acquire a medical image obtained by imaging a luminal organ using a catheter;

specify a direction of interest indicating a direction of a site of interest with respect to the medical image on a basis of the medical image acquired by the acquisition unit, wherein the direction of interest comprises specifying a direction of an epicardium; and

display information indicating the direction of interest specified by the specification unit in association with the medical image or displays the medical image subjected to image processing on a basis of the information indicating the direction of interest.

15 . The image processing device according to claim 14 , wherein the direction of interest is specified by inputting the acquired medical image to a learning model that outputs the direction of interest for the medical image in a case where the medical image is input.

16 . The image processing device according to claim 14 , wherein the control unit is further configured to:

detect a merkmal included in the medical image;

specify the direction of interest on a basis of the merkmal in a case where the detected merkmal is the site of interest; and

specify the direction of interest on a basis of a positional relationship between the merkmal and the site of interest in a case where the detected merkmal is not the site of interest.

17 . The image processing device according to claim 16 , wherein the control unit is further configured to:

acquire a second medical image including the merkmal;

specify a positional relationship between the medical image and the second medical image on a basis of the merkmal included in the medical image and the merkmal included in the second medical image; and

specify the direction of interest on a basis of the specified positional relationship.

18 . The image processing device according to claim 14 , wherein the control unit is further configured to:

specify the direction of interest for each of a plurality of the medical images; and

remove an outlier of the direction of interest specified on a basis of the direction of interest for each of the plurality of the medical images.
