Abstract

An X-ray CT apparatus according to an embodiment includes an X-ray tube, an X-ray detector, a memory, and processing circuitry connected to the memory. The X-ray tube irradiates a subject with X-rays. The X-ray detector detects X-rays emitted from the X-ray tube. The processing circuitry generates a prompt. The processing circuitry inputs the prompt to a generative model and acquires generative information from the generative model. The memory stores, as storage target data, the prompt out of the generative information and the prompt corresponding to the generative information. An embodiment discloses an information processing apparatus including the memory and the processing circuitry connected to the memory, an information processing method, and a recording medium.

First claim

What is claimed is:

1 . An X-ray CT apparatus, comprising:

generate a prompt, and
input the prompt to a generative model and acquire generative information from the generative model, wherein
the memory is configured to store, as storage target data, the prompt out of the generative information and the prompt corresponding to the generative information.

2 . An information processing apparatus, comprising:
at least one memory; and at least one piece of processing circuitry connected to the memory and configured to
generate a prompt, and
input the prompt to a generative model and acquire generative information from the generative model, wherein
the memory is configured to store, as storage target data, the prompt out of the generative information and the prompt corresponding to the generative information.

3 . The information processing apparatus according to claim 2 , wherein
the processing circuitry is configured to generate the prompt to include medical information, and the generative information is a medical image.

4 . The information processing apparatus according to claim 2 , wherein the processing circuitry is configured to store the prompt as the storage target data in the memory when the prompt is input to the generative model.

5 . The information processing apparatus according to claim 4 , wherein the processing circuitry is configured to
receive a user operation to specify the generative information as the storage target data, store the generative information as the storage target data in the memory in accordance with the user operation and store the prompt as the storage target data in the memory regardless of the user operation.

6 . The information processing apparatus according to claim 2 , wherein the processing circuitry is configured to
display icons on a display, the icons receiving a user operation to select, as the storage target data, one or both of the generative information and the prompt corresponding to the generative information, and store, as the storage target data, one or both of the generative information and the prompt corresponding to the generative information in the memory in accordance with the user operation on the icons.

7 . The information processing apparatus according to claim 6 , wherein the icons include a prompt store button causing the prompt corresponding to the generative information to be stored as the storage target data in the memory.

8 . The information processing apparatus according to claim 6 , wherein the icons include a generative information store button causing the generative information to be stored as the storage target data in the memory.

9 . The information processing apparatus according to claim 6 , wherein the icons include a prompt display button that causing the prompt stored in the memory to be displayed on the display.

10 . The information processing apparatus according to claim 2 , wherein
the generative information includes image data, the generative model outputs multiple pieces of the image data, and the processing circuitry is configured to display icons on a display, the icons receiving, for each piece of the image data output from the generative model, a user operation to select the image data as the storage target data.

11 . The information processing apparatus according to claim 2 , wherein the processing circuitry is configured to
evaluate necessity to store the generative information, determine whether to set the generative information as the storage target data based on an evaluation result, and store, as the storage target data, the prompt or both the generative information and the prompt in the memory based on a determination result.

12 . The information processing apparatus according to claim 11 , wherein
the generative information includes information about a patient, and the processing circuitry is configured to evaluate the necessity to store the generative information as being higher as a relevance between the generative information and a diagnostic result for the patient is stronger.

13 . The information processing apparatus according to claim 2 , wherein the processing circuitry is configured to
determine whether to set the generative information as the storage target data, in accordance with a data volume of the generative information, and store, as the storage target data, the prompt or both the generative information and the prompt in the memory based on a determination result.

14 . The information processing apparatus according to claim 2 , wherein
the memory is a non-volatile storage device, and the storage target data stored in the memory is not deleted except when a predetermined deletion condition is met or when a deletion operation is executed by a user.

15 . The information processing apparatus according to claim 2 , wherein the processing circuitry is configured to set the storage target data based on a magnitude of fluctuations of multiple pieces of the generative information generated by the generative model in response to input of the prompt.

16 . The information processing apparatus according to claim 15 , wherein the processing circuitry is configured to determine whether to set the generative information as the storage target data, based on an evaluation result of the magnitude of fluctuations.

17 . The information processing apparatus according to claim 2 , wherein the processing circuitry is configured to acquire restored generative information by inputting the prompt stored as the storage target data in the memory to the generative model, the restored generative information being restored based on the prompt by the generative model.

18 . An information processing method comprising:
generating a prompt; inputting the prompt to a generative model and acquiring generative information from the generative model; and storing, as storage target data in a memory, the prompt out of the generative information and the prompt corresponding to the generative information.

19 . A non-transitory computer readable recording medium on which programmed instructions are recorded, the instructions causing a computer to execute processing, the processing comprising:
generating a prompt; inputting the prompt to a generative model and acquiring generative information from the generative model; and storing, as storage target data in a memory, the prompt out of the generative information and the prompt corresponding to the generative information.
