Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of operating an X-ray imaging apparatus, and more particularly to a method of operating an X-ray imaging apparatus based on an imaging position and an imaging condition at an imaging area of a subject. The present invention relates to an X-ray imaging support system suitable for performing.

[0002]

2. Description of the Related Art When an X-ray imaging apparatus is delivered to a customer, a service technician requires an imaging condition table (X-ray tube tube) corresponding to the imaging site (skull, mandible, sinus, etc.) described in an instruction manual. Using the voltage, the tube current, the imaging time, the distance from the X-ray tube to the subject, and the number of grids, the handling of the device was explained to the customer.

[0003]

Since there is no radiologist who is accustomed to the operation of the X-ray imaging apparatus, the practitioner himself or herself is inexperienced in operating the apparatus. For this reason, the user is unfamiliar with the setting of the photographing conditions and the photographing technique, and the man-hours required for the service staff to explain the handling and attend the ceremony have increased. This man-hour varied depending on the experience of service personnel. Especially for inexperienced service personnel,
There is no explanation that gives the doctor the satisfaction of the imaging conditions.

[0004] In addition, since a part which is frequently photographed (such as the chest, abdomen, and lumbar region) is repeatedly photographed, a practitioner can quickly understand the photographing method and photographing conditions.
Parts that are rarely photographed (head, upper limb, lower limb, etc.) required the explanation of a service representative each time. Furthermore, in the early days of the opening of the business, doctors lacked experience in the imaging method, so they did not know how to position the imaging position (positioning). The number of man-hours required for service staff to explain to doctors has increased due to the fact that there is almost no service.

It is an object of the present invention to provide a support system for an X-ray imaging apparatus that can eliminate the insufficiency of handling explanations by service personnel and enable a physician unfamiliar with the operation to perform a simple operation.

[0006]
