1. An X-ray imaging apparatus comprising:
an X-ray irradiation unit including an X-ray tube;
a detector configured to detect X-rays emitted from the X-ray irradiation unit;
an image generation unit configured to generate an X-ray image based on the X-rays detected by the detector;
an optical imaging unit configured to capture an optical image in a direction of a subject and the detector from a side of the X-ray irradiation unit;
a storage unit configured to store a trained model for outputting determination information for an input image based on the optical image including the subject imaged by the optical imaging unit, the determination information determining a state regarding an imaging range of a predetermined site of the subject or a relative position of the predetermined site to another site of the subject;
a control unit configured to acquire the determination information, using the trained model; and
a notification unit configured to perform notification based on the determination information acquired by the control unit,
wherein the control unit is configured to acquire:
determination information for determining a state regarding an imaging range of apex area of a lung of the subject, the determination information being outputted from the trained model,
determination information for determining a state regarding a relative position of the apex area of the lung to a clavicle of the subject,
determination information for determining a state regarding a relative position of a lung field to a scapula of the subject, or
determination information for determining a state of internal rotation of an arm of the subject serving an index of overlap between the long field and the scapula of the subject.
