Abstract

[Problem] To improve the operability of multiple images captured during an operation triggered by a single shooting command. [Solution] The radiation imaging apparatus comprises: an imaging unit that irradiates radiation to capture still and moving images; a control unit that controls the imaging unit to operate in a first imaging mode in which it captures one or both still and moving images multiple times between the start and end of the operation of the imaging unit by a single imaging instruction; and a storage unit that stores information related to the imaging instruction and multiple images captured in the first imaging mode in association with each other.

Description

This invention relates to a radiographic imaging apparatus, a radiographic imaging method, and a radiographic imaging program. To observe the inside of a patient's (subject's) body in real time, a fluoroscopy system is known that irradiates the patient with radiation and takes images, displaying a real-time video of the patient's internal organs (see, for example, Patent Document 1). For example, such a fluoroscopy system is often used when performing procedures such as inserting a catheter into a patient's body. Fluoroscopy equipment requires a dedicated system and is installed in a dedicated imaging room. Due to the high radiation exposure, it cannot be used in situations outside the imaging room, such as during ward rounds or in emergency situations. Therefore, for example, in cases where imaging is needed to monitor the progress during a procedure or to confirm the internal condition during contrast agent injection, it was necessary to move the patient to the dedicated imaging room regardless of their physical condition, placing a significant burden on the patient. In contrast to such fluoroscopy equipment, a new type of radiographic imaging system is beginning to gain popularity. While an extension of existing radiation imaging techniques, it utilizes pulsed radiation for continuous imaging, enabling the display of the patient's internal organs as video and allowing for image analysis. This type of radiographic imaging system can be mounted on mobile medical units and, by implementing radiation exposure management such as setting limits on radiation dose, enables video recording even in locations where fluoroscopy equipment cannot be used.
