Sites such as hospitals where these medical devices are installed and operated are systematized and labor-saving, and the work of medical staff is being shared. Each of these medical devices is generally installed in a dedicated examination room or treatment room for each device, and the subject enters the examination room or treatment room by himself / herself or a transporter called a stretcher. With the patient placed on the bed, medical staff such as nurses carry the patient into an examination room or treatment room, where medical images are collected and treated. In such a situation, the medical staff checks the name of the subject, collects medical images specified by a doctor, and performs treatment on the subject.
[0003]
When collecting or treating medical images, enter information about the subject (such as subject ID, name, gender, date of birth, etc.) and information on imaging or treatment conditions into the medical device in advance. Can be kept. Heretofore, there has been a medical image diagnostic apparatus in which input reference means for inputting and referring to these various conditions are provided at two places of a console and a gantry. (See, for example, Patent Document 1.) The input reference means provided at the two positions of the console and the gantry are so-called double consoles having the same functions.
In addition, a non-contact data carrier in which personal data is written is directly attached to a part of the body of the individual, and the personal data written in the non-contact data carrier is read by a portable reading device. A personal authentication system that performs personal authentication by reading in the form of a personal computer and avoids misidentification of hospitalized patients has been proposed. (See, for example, Patent Document 2)

JP-A-5-269117 (page 3, FIG. 1)
[Patent Document 2]
JP-A-2000-31194 (page 2, FIG. 1)
[Problems to be solved by the invention]
However, when confirming the name of the subject using the double console, the medical staff who is busy with the work is required to provide information on the subject (subject ID, name, gender, date of birth, etc.) and imaging. -Information on the subject must be searched for from information such as information on treatment-related conditions. That is, for example, in the case of an X-ray CT apparatus, information on the subject, setting of the imaging region, tube current of the X-ray tube, the imaging site, the direction of insertion of the subject into the gantry (insert from the foot) , Or from the head) to find information about the subject from information on a large number of conditions relating to imaging. Also, in the case of the MRI apparatus, there are a large number of conditions related to imaging and treatment such as an imaging region, an imaging pulse sequence (each value such as a repetition time of the imaging pulse sequence), an imaging region, and a direction in which a subject is inserted into a gantry. The information must be used to find the subject's information.
