Abstract

Candidate positions of a plurality of lesion candidate region images obtained by performing an image analysis process for a medical image are displayed on schematic diagrams of a human body. Lesion candidate region images other than a lesion candidate region image corresponding to a denied candidate position where a denial operation has been received are registered as correct answer data or the lesion candidate region images corresponding to confirmed candidate positions where a confirmation operation has been received are registered as the correct answer data.

First claim

What is claimed is:

1. A learning data creation support apparatus comprising:
a display displays candidate positions of a plurality of lesion candidate region images obtained by performing an image analysis process for a medical image on a schematic diagram of a human body; and
a processor configured to,
receive a designation of a denial operation to all of at least one of the candidate positions that are denied; and
after receiving a designation of the denial operation, register, as correct answer data, lesion candidate region images other than a lesion candidate region image corresponding to the at least one denied candidate positions where the denial operation has been received,

wherein the processor further registers, as incorrect answer data, the lesion candidate region image corresponding to the at least one denied candidate positions and lesion candidate region images other than the lesion candidate region image corresponding to a confirmed candidate position.

2. The learning data creation support apparatus according to claim 1 ,
wherein marks are provided at a plurality of candidate positions on the schematic diagram of the human body, and
the denial operation is an operation of removing the mark displayed at the candidate position.

3. The learning data creation support apparatus according to claim 2 ,
wherein marks are provided at a plurality of candidate positions on the schematic diagram of the human body, and
the processor further configured to
record a schematic diagram in which the marks are put at candidate positions other than the at least one denied candidate positions in a case in which the denial operation has been received in an interpretation report, or
record a schematic diagram in which the mark is put at the confirmed candidate position in a case in which the confirmation operation has been received in an interpretation report.

4. The learning data creation support apparatus according to claim 2 ,
wherein the schematic diagram is a schema diagram.

5. The learning data creation support apparatus according to claim 1 ,
wherein marks are provided at a plurality of candidate positions on the schematic diagram of the human body, and
the denial operation is an operation of removing the mark displayed at the candidate position.

6. The learning data creation support apparatus according to claim 1 ,
wherein marks are provided at a plurality of candidate positions on the schematic diagram of the human body, and
the processor further configured to
record a schematic diagram in which the marks are put at candidate positions other than the at least one denied candidate positions in a case in which the denial operation has been received in an interpretation report, or
record a schematic diagram in which the mark is put at the confirmed candidate position in a case in which the confirmation operation has been received in an interpretation report.

7. The learning data creation support apparatus according to claim 6 ,
wherein the schematic diagram is a schema diagram.

8. The learning data creation support apparatus according to claim 1 ,
wherein marks are provided at a plurality of candidate positions on the schematic diagram of the human body, and
the processor further configured to
record a schematic diagram in which the marks are put at candidate positions other than the at least one denied candidate positions in a case in which the denial operation has been received in an interpretation report, or
record a schematic diagram in which the mark is put at the confirmed candidate position in a case in which the confirmation operation has been received in an interpretation report.

9. The learning data creation support apparatus according to claim 1 ,
wherein the image analysis process is a process of detecting the lesion candidate region image with a discriminator that has learned the correct answer data, and
the processor further configured to cause the discriminator to relearn the registered correct answer data.

10. The learning data creation support apparatus according to claim 9 ,
wherein the schematic diagram is a schema diagram.

11. The learning data creation support apparatus according to claim 1 ,
wherein the image analysis process is a process of detecting the lesion candidate region image with at least one of a discriminator that has learned the correct answer data or a discriminator that has learned the incorrect answer data, and
the processor further configured to cause the discriminator to relearn at least one of the registered correct answer data or the registered incorrect answer data.

12. The learning data creation support apparatus according to claim 11 ,
wherein the schematic diagram is a schema diagram.

13. The learning data creation support apparatus according to claim 1 ,
wherein the schematic diagram is a schema diagram.

14. The learning data creation support apparatus according to claim 1 ,
wherein the schematic diagram is a schema diagram.

15. A learning data creation support method performed in a learning data creation support apparatus, the method comprising:
displaying candidate positions of a plurality of lesion candidate region images obtained by performing an image analysis process for a medical image on a schematic diagram of a human body;
receiving a designation of a denial operation to all of at least one of the candidate positions that are denied and after receiving a designation of the denial operation, registering, as correct answer data, lesion candidate region images other than a lesion candidate region image corresponding to the at least one denied candidate positions where the denial operation has been received, and
registering, as incorrect answer data, the lesion candidate region image corresponding to the at least one denied candidate positions and lesion candidate region images other than the lesion candidate region image corresponding to a confirmed candidate position.

16. A non-transitory computer readable recording medium storing a learning data creation support program that causes a computer to:
display candidate positions of a plurality of lesion candidate region images obtained by performing an image analysis process for a medical image on a schematic diagram of a human body;
receive a designation of a denial operation to all of at least one of the candidate positions that are denied and after receiving a designation of the denial operation, registering, as correct answer data, lesion candidate region images other than a lesion candidate region image corresponding to the at least one denied candidate positions where the denial operation has been received, and
register, as incorrect answer data, the lesion candidate region image corresponding to the at least one denied candidate positions and lesion candidate region images other than the lesion candidate region image corresponding to a confirmed candidate position.

17. A learning data creation support apparatus comprising:
a memory that stores commands for causing a computer to perform processes; and
a processor that is configured to execute the stored commands,
wherein the processor displays candidate positions of a plurality of lesion candidate region images obtained by performing an image analysis process for a medical image on a schematic diagram of a human body, and
the processor receives a designation of a denial operation to all of at least one of the candidate positions that are denied; and after receiving a designation of the denial operation, registers, as correct answer data, lesion candidate re
