Abstract
An information processing apparatus according to the present disclosure includes a processor, in which the processor is configured to acquire a low-energy image captured by irradiating a subject into which a contrast agent has been injected with radiation having a first energy, and a high-energy image captured by irradiating the subject with radiation having a second energy higher than the first energy, generate an initial energy difference image by performing difference processing on the low-energy image and the high-energy image, extract an artifact component from the initial energy difference image; and generate an energy difference image by performing the difference processing again based on the artifact component.

An information processing apparatus comprising:
- a processor,
- wherein the processor is configured to:
- acquire a low-energy image captured by irradiating a subject into which a contrast agent has been injected with radiation having a first energy, and a high-energy image captured by irradiating the subject with radiation having a second energy higher than the first energy;
- generate an initial energy difference image by performing difference processing on the low-energy image and the high-energy image;
- extract an artifact component from the initial energy difference image;
- and
- generate an energy difference image by performing the difference processing again based on the artifact component.
An information processing method comprising:
- acquiring a low-energy image captured by irradiating a subject into which a contrast agent has been injected with radiation having a first energy, and a high-energy image captured by irradiating the subject with radiation having a second energy higher than the first energy;
- generating an initial energy difference image by performing difference processing on the low-energy image and the high-energy image;
- extracting an artifact component from the initial energy difference image;
