BRIEF SUMMARY
DESCRIPTION
1. Technical Field
The present invention relates to a method of an apparatus for photographing a medical image obtained by an X-ray computer tomograph (hereinunder referred to as "CT") by a camera and more particularly, to a method of and an apparatus for photographing a plurality of medical images automatically and successively which are registered in advance to be photographed.
2. Background Art
As an example of medical image photographing apparatus, a CT is known. A CT is provided with an image display unit for displaying an image on the basis of video signals, the image having been subjected to processings for facilitating diagnosis, for example, window processing, ROI setting processing and image enlarging processing; and a multi format camera (hereinunder referred to as "MFC") for photographing a plurality of images on the basis of the video signals at predetermined positions of a film surface. Such an MFC includes a photographing CRT for displaying an image on the basis of a video signal supplied from the image display unit, a film setting mechanism for setting the film at a predetermined photographing position and carrying the film to a predetermined storing position after photographing, a plurality of lenses having the respective shutters which are provided between the film and the photographing CRT, and a camera controller for controlling the film setting mechanism and the shutters, etc. on the basis of the various command signals (a photographing starting signal, etc.) supplied from the outside and detection signals supplied from various sensors (a film position sensor, etc.) at the interior. These film setting mechanisms and the shutters, etc. are hereinunder referred to as the "mechanical unit" of a camera.
In such a computer tomography, during scanning and diagnosis the images displayed on the image display unit is observed, and a given image is photographed by the MFC as desired. When an image is photographed by the MFC, a key on the console panel of the image display unit is first operated by the operator to display an image to be photographed on both the display unit and the photographing CRT, and the photographing key of the console panel of the MFC is then depressed.
In such a conventional medical image photographing apparatus, when many pictures are photographed successively by the MFC, it is necessary to repeat the operation of the console panels of the image display unit and the MFC as many times as the photographing frames, which requires much labor and time of the operator.
DISCLOSURE OF THE INVENTION
Accordingly, it is an object of the present invention to provide a method of and an apparatus for photographing a medical image which is capable of successively photographing a plurality of medical images by an MFC without requiring a labor of the operator and in a short time. A method of and an apparatus for photographing a medical image according to the present invention are characterized in that information for specifying a plurality of images to be successively photographed is registered on a frame of a display unit (3), and video signals of the plurality of images are supplied to a multi format camera (8) in succession with reference to the registered information by a controller (2) in order to photograph the plurality of images automatically and successively.
