Abstract

A diagnosis support apparatus provides information for supporting medical diagnosis. The diagnosis support apparatus includes: a selection unit configured to select reference information as a clue for medical diagnosis from reference information candidates generated by using medical information; an obtaining unit configured to obtain an image feature corresponding to the reference information from a medical image; a specifying unit configured to specify a partial region of the medical image based on the reference information and the image feature; and a display control unit configured to control display of the medical image based on the selected reference information and the partial region.

First claim

What is claimed is:

1. A diagnosis support apparatus which provides information for supporting medical diagnosis, the apparatus comprising:
a selection unit configured to select an imaging finding as a clue for medical diagnosis from candidates of the imaging finding generated by using medical information;
an obtaining unit configured to obtain an image feature corresponding to the selected imaging finding from a medical image;
a specifying unit configured to specify a portion in an abnormal shadow on the basis of the image feature, the portion being a partial region indicated by the selected imaging finding; and
a display control unit configured to display, on a display unit, the specified portion in the abnormal shadow included in the medical image together with a remaining region included in the medical image by displaying the medical image, wherein
the display control unit is configured to display, on the display unit, the specified portion in the abnormal shadow or a portion in the vicinity of the specified portion in the abnormal shadow so as to emphasize the specified portion in the abnormal shadow or the portion in the vicinity of the specified portion in the abnormal shadow compared to the displayed remaining region.

2. The apparatus according to claim 1 , wherein the display control unit is configured to display identification information for identifying the specified portion in the abnormal shadow on or in the vicinity of the portion in the abnormal shadow.

3. The apparatus according to claim 1 , wherein the display control unit is configured to change a display attribute of the specified portion in the abnormal shadow or a display attribute of the portion in the vicinity of the portion in the abnormal shadow.

4. The apparatus according to claim 1 , wherein the display control unit is configured to control the display of a region having the image feature corresponding to the imaging finding as the portion in the abnormal shadow.

5. The apparatus according to claim 1 , wherein the display control unit is configured to display information on the imaging finding and the portion in the abnormal shadow having undergone control of the display in combination with each other.

6. The apparatus according to claim 1 , wherein the specifying unit is configured to specify, as the portion in the abnormal shadow, a region having the image feature corresponding to the imaging finding.

7. The apparatus according to claim 1 , wherein the obtaining unit is configured to obtain an image feature of a medical image as a diagnosis target by performing image processing for the medical image based on input information obtained by the input information obtaining unit.

8. The apparatus according to claim 7 , wherein the obtaining unit is configured to perform the image processing for a region obtained based on coordinate information included in the input information.

9. The apparatus according to claim 1 , further comprising a deriving unit configured to derive an imaging finding based on an image feature obtained by the obtaining unit, wherein
the deriving unit is configured to derive an imaging finding as a diagnosis target from a comparison result on the image feature and a threshold.

10. The apparatus according to claim 9 , further comprising an inference unit configured to execute inference for obtaining a diagnosis name corresponding to the diagnosis target and an inference probability corresponding to the diagnosis name based on input information obtained by the input information obtaining unit and the imaging finding derived by the deriving unit.

11. The apparatus according to claim 10 , wherein the inference unit is configured to obtain the inference probability with respect to each of a plurality of diagnosis names as a result of the inference.

12. The apparatus according to claim 10 , wherein the inference unit is configured to obtain an influence degree of evidence information used to obtain a result of the inference with respect to the inference probability as an influence degree of the candidate by using the inference probability and the evidence information.

13. The apparatus according to claim 12 , wherein the inference unit is configured to obtain, as the candidate, non-input information, of input information obtained by the input information obtaining unit, which has not been input to the inference unit.

14. The apparatus according to claim 13 , wherein the inference unit is configured to obtain a change in the inference probability in a case where the non-input information is added to the evidence information as an influence degree of the candidate corresponding to the non-input information.

15. The apparatus according to claim 12 , wherein the selection unit is configured to select, based on the inference probability and influence degrees of the candidates which are obtained by the inference unit, an imaging finding from the candidates.

16. The apparatus according to claim 10 , wherein the display control unit is configured to display information on the imaging finding, the portion in the abnormal shadow having undergone control of the display, and a result of the inference in combination with each other.

17. An information processing method for providing information for supporting medical diagnosis, the method comprising:
selecting an imaging finding as a clue for medical diagnosis from candidates of the imaging finding generated by using medical information;
obtaining an image feature corresponding to the selecting imaging finding from a medical image;
specifying a portion in an abnormal shadow on the basis of the image feature, the portion being a partial region indicated by the selected imaging finding; and
displaying, on a display unit, the specified portion in the abnormal shadow included in the medical image together with a remaining region included in the medical image by displaying the medical image, wherein
the displaying includes displaying, on the display unit, the specified portion in the abnormal shadow or a portion in the vicinity of the specified portion in the abnormal shadow so as to emphasize the specified portion in the abnormal shadow or the portion in the vicinity of the specified portion in the abnormal shadow compared to the displayed remaining region.

18. A non-transitory computer-readable storage medium storing a program for causing a computer to function as each unit of a diagnosis support apparatus, the diagnosis support apparatus comprising:
a selection unit configured to select an imaging finding as a clue for medical diagnosis from candidates of the imaging finding generated by using medical information;
an obtaining unit configured to obtain an image feature corresponding to the selected imaging finding from a medical image;
a specifying unit configured to specify a portion in an abnormal shadow on the basis of the image feature, the portion being a partial region indicated by the selected imaging finding; and
a display control unit configured to display, on a display unit, the specified portion in the abnormal shadow included in the medical image together with a remaining region included in the medical image by displaying the medical image, wherein
the display control unit is configured to control display, on the display unit, the specified portion in the abnormal shadow or a portion in the vicinity of the specified portion in the abnormal shadow so as to emphasize the specified portion in the abnormal shadow or the portion in the vicinity of the specified portion in the abnormal shadow compared to the displayed rema
