Abstract

An information processing device is provided that includes an identification data acquisition unit that acquires image data for identification in which a first biological region is captured and first site information of the first biological region, and an identification unit that selects an identifier corresponding to the first site information from identifiers associated respectively with a plurality of pieces of site information, and performs an identification process on the basis of the identifier and the image data for identification.

First claim

1 . An information processing device comprising:
an identification data acquisition unit that acquires image data for identification in which a first biological region is captured and first site information of the first biological region; and an identification unit that selects an identifier corresponding to the first site information from identifiers associated respectively with a plurality of pieces of site information, and performs an identification process on a basis of the identifier and the image data for identification.

2 . The information processing device according to claim 1 , further comprising
an output unit that outputs an identification result obtained by the identification process.

3 . The information processing device according to claim 2 , wherein
the identification result includes at least one of a diagnostic result or an analysis result corresponding to the first biological region.

4 . The information processing device according to claim 3 , wherein
the diagnostic result includes information regarding whether or not a subject having the first biological region in a body has a disease.

5 . The information processing device according to claim 3 , wherein
the analysis result includes at least one of presence or absence of a lesion in the first biological region, a probability that a lesion is included in the first biological region, a location of the lesion, or a type of the lesion.

6 . The information processing device according to claim 2 , wherein
the output unit outputs information regarding a learner used to generate model data used by the identifier.

7 . The information processing device according to claim 2 , wherein
the identification data acquisition unit acquires first staining information, and the identification unit selects an identifier corresponding to the first site information and the first staining information from identifiers associated respectively with a plurality of combinations of site information and staining information, and performs the identification process on a basis of the identifier and the image data for identification.

8 . The information processing device according to claim 1 , wherein
in a case where scan data including the image data for identification is acquired from a reading device, the identification data acquisition unit acquires the image data for identification on a basis of the scan data.

9 . The information processing device according to claim 8 , wherein
in a case where the scan data including the first site information is acquired from the reading device, the first site information is recognized on a basis of the scan data.

10 . The information processing device according to claim 8 , wherein
in a case where the scan data including first specimen information is acquired from the reading device, the first specimen information is recognized from the scan data, and the first site information corresponding to the first specimen information is acquired from another information processing device.

11 . The information processing device according to claim 1 , wherein
the identifier is implemented by a neural network, a random forest, a support vector machine, or AdaBoost.

12 . The information processing device according to claim 1 , wherein
the first site information is information in which the first biological region is classified into clinically meaningful predetermined units.

13 . The information processing device according to claim 12 , wherein
the units are one of an organ system, an organ, a tissue, and a disease code.

14 . The information processing device according to claim 1 , further comprising:
a learning data acquisition unit that acquires image data for learning in which a second biological region is captured and second site information of the second biological region; and a learning unit that selects a learner corresponding to the second site information from learners associated respectively with the plurality of pieces of site information, and generates model data corresponding to the second site information among pieces of model data associated respectively with the plurality of pieces of site information on a basis of the learner and the image data for learning.

15 . The information processing device according to claim 14 , wherein
the learning data acquisition unit acquires correct answer data corresponding to the image data for learning, and the learning unit generates the model data on a basis of the learner, the image data for learning, and the correct answer data.

16 . The information processing device according to claim 14 , wherein
the learning data acquisition unit acquires second staining information, and the learning unit selects a learner corresponding to the second site information and the second staining information, and generates the model data on a basis of the learner and the image data for learning.

17 . The information processing device according to claim 14 , wherein
in a case where the model data corresponding to the second site information already exists, the learning unit determines whether or not to newly generate the model data on a basis of accuracy of the model data.

18 . An information processing method comprising:
acquiring, by a processor, image data for identification in which a first biological region is captured and first site information of the first biological region; and selecting, by the processor, an identifier corresponding to the first site information from identifiers associated respectively with a plurality of pieces of site information, and performing, by the processor, an identification process on a basis of the identifier and the image data for identification.

19 . An information processing system comprising
an information processing device, wherein the information processing device includes: an imaging unit that captures an image of a first biological region; an identification data acquisition unit that acquires image data of the first biological region captured by the imaging unit and first site information of the first biological region; and an identification unit that selects an identifier corresponding to the first site information from identifiers associated respectively with a plurality of pieces of site information, and performs an identification process on a basis of the identifier and the image data.

20 . An information processing system comprising a medical image imaging device and software used for processing image data corresponding to an object imaged by the medical image imaging device, wherein
the software causes an information processing device to execute an identification process based on first image data corresponding to a first biological region and an identifier corresponding to the first site information of the first biological region.
