Abstract: The radiographic imaging apparatus includes a preset setting unit for presetting a dose of X-rays, a standard state setting unit for setting the preset dose as a standard state, and a dose change unit for relatively changing the dose of X-rays from the standard state to at least one of a high-dose state in which the dose of the X-rays is higher than that in the standard state by a predetermined dose and a low-dose state in which the dose of the X-rays is lower than that in the standard state by a predetermined dose.

Abstract: This X-ray imaging apparatus (100) is provided with an X-ray irradiation unit (2), an X-ray detection unit (3), a pulse width setting unit (72) for setting a pulse width of X-rays to be emitted, an X-ray irradiation control unit (71) for causing the X-rays to emit from the X-ray irradiation unit (2), an X-ray image generation unit (73) for generating an X-ray image (10), and a device detection unit (74) for detecting, based on a trained model (80) generated by machine learning, the device (200) reflected in the X-ray image (10). The pulse width is a blur suppression pulse width equal to or less than a pulse width at which detection accuracy of detecting the device (200) based on the trained model (80) is maximized.
