In a medical imaging device (imaging device) installed in a hospital, imaging of a patient is performed based on examination request information instructed by a doctor. Examination request information includes basic patient information (patient ID, name, gender, date of birth, etc.), imaging condition information (examination date and time, location, direction, left and right, tube voltage, tube current, mechanical material, etc.) inherent to the patient.

The medical radiographer operates the medical imaging equipment by referring to the basic patient information and imaging condition information on the screen of a computer called a console connected to the medical imaging equipment. Part of the patient's basic information and shooting condition information is transferred from the console to the medical imaging device, and the medical imaging device performs shooting based on the information.

In hospitals, various medical information about patients is often required. Therefore, a medical information browsing system has been proposed that stores medical information in folders for each browsing item, each patient, and each imaging date, and enables browsing of medical information from a computer terminal connected to a network (see Patent Document 1).
