ABSTRACT:
BACKGROUND OF THE INVENTION
a) Field of the Invention
This invention relates to a filing device for one or more developed X-ray films (hereinafter called a “developed X-ray film filing device”).
b) Description of the Related Art
X-ray photography is widely used especially in the medical field. Exposed X-ray films are developed, and are then stored in or on X-ray film filing devices such as files, folders and slide mounts.
Such X-ray film filing devices include those making use of sheets having light-transmitting properties. Filing devices of this type, with films still filed in or on the devices, permit diagnosis or observation of the films by illuminating the films at the back sides thereof.
Upon diagnosis or observation of a particular site, such as a tooth, in an X-ray film filed in or on an X-ray film filing device of this type, precise determination of the size or relative position of the site requires to remove the film from the filing device and then to affect the diagnosis or observation by using another instrument or device.
SUMMARY OF THE INVENTION
With the foregoing inconvenience in view, the present invention has as an object thereof the provision of an X-ray film filing device which permits precise and easy diagnosis or observation of the size, relative position or the like of a particular site in an X-ray film while the X-ray is still filed in or on the filing device.
To achieve the above-described object, the present invention provides a developed X-ray film filing device for filing a developed X-ray film, which is composed of a transparent sheet having scale marks applied thereon. The transparent sheet is arranged such that a particular site appeared in the X-ray film can be diagnosed using the scale marks.
Filing of the X-ray film in or on the filing device allows a viewer to observe the X-ray film and the scale marks in an overlapped state, so that the size or relative position of the particular site can be precisely and easily determined without removal of the X-ray film from the filing device. Further, measurements can also be performed with ease on teeth (root canal lengths and the like).
