## Abstract

An ultrasonic diagnostic device includes a processor including hardware, the processor being configured to: analyze a first examination performed on a subject using first ultrasound image data of an ultrasound image of the subject to be diagnosed; calculate a rate of accuracy of diagnosis in a case where a second examination is performed on the subject based on an analysis result of the first examination performed on the subject, analysis results of the first examination performed on a plurality of sample subjects, and analysis results of the second examination performed on the plurality of sample subjects; and control a display device to display the rate of accuracy of diagnosis.

## Claims

### Claim 1

An ultrasonic diagnostic device comprising
a processor comprising hardware, the processor being configured to:
analyze a first examination performed on a subject using first ultrasound image data of an ultrasound image of the subject to be diagnosed;
calculate a rate of accuracy of diagnosis in a case where a second examination is performed on the subject based on an analysis result of the first examination performed on the subject, analysis results of the first examination performed on a plurality of sample subjects, and analysis results of the second examination performed on the plurality of sample subjects; and
control a display device to display the rate of accuracy of diagnosis;
wherein the processor is configured to calculate the rate of accuracy by:
calculating a probability of a disease of the subject based on the first examination; and
calculating the rate of accuracy of diagnosis using the probability of the disease of the subject and probabilities of diseases of the sample subjects based on the first examination and the second examination.

### Claim 2 (depends on 1)

The ultrasonic diagnostic device according to claim 1, wherein the processor is configured to calculate a rate of sample subjects for which probabilities of diseases based on the second examination are equal to or higher than a threshold among the sample subjects for which probabilities of diseases based on the first examination are a same as the probability of disease of the subject to be diagnosed and calculates the rate of accuracy of diagnosis using the calculated rate.

### Claim 3 (depends on 1)

The ultrasonic diagnostic device according to claim 1, further comprising an input unit configured to accept input of information, wherein
the processor is configured to:
analyze the first examination for each disease candidate,
calculate the rate of accuracy of diagnosis for each disease candidate;
control the display device to display an analysis result for each disease candidate; and
control, in a case where the input unit accepts input of selection of one disease candidate, the display device to display the rate of accuracy of diagnosis for the selected disease candidate.

### Claim 4 (depends on 1)

The ultrasonic diagnostic device according to claim 1, wherein the processor is configured to analyze the first examination by inputting the first ultrasound image data to a learned model generated through machine learning.

### Claim 5 (depends on 4)

The ultrasonic diagnostic device according to claim 4, wherein the learned model is a model learned by using second ultrasound image data and a diagnosis based on the second ultrasound image data.

### Claim 6

An operation method of an ultrasonic diagnostic device, comprising:
analyzing a first examination performed on a subject using first ultrasound image data of an ultrasound image of the subject to be diagnosed;
calculating a rate of accuracy of diagnosis in a case where a second examination is performed on the subject based on an analysis result of the first examination performed on the subject, analysis results of the first examination performed on a plurality of sample subjects, and analysis results of the second examination performed on the plurality of sample subjects; and
controlling a display device to display the rate of accuracy of diagnosis;
wherein the calculating of the rate of accuracy comprises:
calculating a probability of a disease of the subject based on the first examination; and
calculating the rate of accuracy of diagnosis using the probability of the disease of the subject and probabilities of diseases of the sample subjects based on the first examination and the second examination.

### Claim 7

A non-transitory computer-readable recording medium on which an executable program is recorded, the program causing a processor of a computer to execute:
analyzing a first examination performed on a subject using first ultrasound image data of an ultrasound image of the subject to be diagnosed;
calculating a rate of accuracy of diagnosis in a case where a second examination is performed on the subject based on an analysis result of the first examination performed on the subject, analysis results of the first examination performed on a plurality of sample subjects, and analysis results of the second examination performed on the plurality of sample subjects; and
controlling a display device to display the rate of accuracy of diagnosis;
wherein the calculating of the rate of accuracy comprises:
calculating a probability of a disease of the subject based on the first examination; and
calculating the rate of accuracy of diagnosis using the probability of the disease of the subject and probabilities of diseases of the sample subjects based on the first examination and the second examination.
