Abstract

PURPOSE:To reduce the labor and the time required for hard copy, by automatizing entirely or partially manual operations of a diagnostic image photographing device used for the hard copy of various medical diagnostic devices controlled by computers. CONSTITUTION:A computer CPU12 issues a shutter closing signal to an optical system controlling mechanism 30 by the signal from a sensor 29S of an exposure detecting circuit 29, and a shutter operator 7A is operated to close a lens 5A, and the shutter of a next lens 5B is opened. Four lenses 5A-5D are opened and closed successively in this manner, and four diagnostic images are printed on a film 3 with a prescribed exposure, and thereafter, a sensor 31S of a film loading and unloading mechanism sends a photography and signal to the computer CPU12. The computer CPU12 instructs a film loading and unloading mechanism 31 to transfer the printed film to a film developing and fixing mechanism 32 and instructs the mechanism 31 to load a new film.

Description

DETAILED DESCRIPTION OF THE INVENTION In order to save diagnostic images of ME devices such as radiation computed tomography devices and ultrasonic layer diagnosis devices, the present invention uses a CRT SC as an input signal on a television image signal of the device. The present invention relates to an automatic diagnostic image photographing device that displays an image and sequentially records the displayed image on a plurality of divided photographic films.

Conventionally, an image capturing device called a multi-imager has been used to obtain a photographic image 1 for data storage of the above-mentioned medical diagnostic equipment. This device includes, for example, a CRT (11), an optical system (2) and a film (3) as shown in FIG.
The three elements are housed outside (not shown), and the CRT is

A frame-by-frame diagnostic image is taken. In this way, replace the cassettes one after another and repeat the same operation (return 9 times and repeat many steps).
f) A diagnostic image is taken.

However, in order to diagnose and record a large number of patients in a hospital or the like, it is necessary to manually operate the image capturing apparatus as described above dozens to hundreds of times a day. These manual operations include loading and unloading the film cassette, adjusting the dial to set the exposure level, operating the shooting button, and then developing and fixing the photographed film using the developing machine, which can be repeated dozens to hundreds of times. Manual manipulation of hard copies is a time-consuming and labor-intensive task.

The present invention has been made in view of the above-mentioned current situation, and it automatically monitors and monitors the manual operation of an image capturing device, which is performed to save diagnostic images of various conventional computer-controlled medical diagnostic devices, according to instructions from the computer. This is to save a great deal of effort and time.

That is, in an apparatus equipped with a medical diagnostic device controlled by a computer, and a photographing device that displays a diagnostic image obtained by this diagnostic device on a CRTg surface and sequentially records the displayed image on a plurality of divided photographic films, This invention relates to a diagnostic wi* automatic imaging device characterized in that the imaging device is controlled by a diagnostic device control combinator and its control state is monitored.

The present invention will be explained in detail below with reference to the drawings. FIG. 2 is a block diagram of a configuration in which the automatic diagnostic image capturing apparatus according to the present invention is combined with, for example, an X-ray combinator tomography apparatus.

The left side of the dotted line in the center of the figure is each block of the X-ray beam tomography system.
For example, head and neck diagnostic image data of a subject obtained by a diagnostic data acquisition circuit α such as an A10 conversion circuit is sent to a computer cpu@. The above image data is corrected by a computer CPU (12), and a diagnostic data processing circuit that performs composite and scene calculations as an X-ray cross-layer reconstruction method is used. The image data is reproduced by the computer CPU A2, and then transferred and stored in an image data storage device such as a magnetic tape, magnetic disk, or η-type magnetic tape under the control of the computer CPU A2.At the same time, the image data is 9-a) and is displayed on the CRT monitor aaw screen via the video signal generating circuit α9.The video signal displayed on the CRT monitor passes through the transmission line circle and is used for diagnosis and image capture by, for example, the multi-imager mentioned above.

l) A diagnostic image is reproduced on the lit surface. The configuration described above is that of a conventional device, and the features of the device according to the present invention include each boot stall fought in the chain 1129 and its operation. In other words, the combination controller CPU (L2) controls the control circuit @7 via the imaging device interface (to) and automatically operates the imaging device. First,

At the same time, an exposure detection circuit (295) for detecting the exposure on the film is activated, and when a preset exposure level is reached, the sensor (295) of the circuit sends a signal to the computer CPU. In response to this signal, the computer cpu issues a shutter close signal to the optical system control mechanism cent, for example the shutter operation I! explained in FIG.
(7A) to close the lens (5A) and open the shutter of the next lens (SB). In this way, for example, the four lenses (5A) to (5D) are sequentially opened and closed, and when the four dllllkfr field images are printed on the film (3) each with a predetermined exposure amount, the Senna (115) of the film loading/unloading mechanism sends a signal indicating the end of photographing to computer CPU A2. combiator c
pu a2 instructs the film loading/unloading mechanism Cl1l to transfer the photographed film to the film developing and fixing mechanism (to), and also loads a new film (m+). The film developing and fixing mechanism automatically develops and fixes the transferred film, and either accumulates it at a predetermined position or carries it out of the apparatus. In this way, each part of the photographing device informs the CPU (12) of its respective status.
By automatically operating according to the operation program programmed by the operator in advance or each time, it is possible to make hard copies of dozens or more diagnostic images without the need for any manual operations during the process.
This can be done unattended, such as at night.

The above is an embodiment of the present invention, but the present invention is not limited to the fully automatic device described above; for example, a developing and fixing device may be provided separately, or due to the amount of hard copies, only film loading and unloading may be performed manually. It can also be applied to semi-automatic equipment.

It is also possible to provide a dedicated microprocessor or logic electronic circuit in place of the control computer of the medical diagnostic device, and configure these to work in conjunction with the medical diagnostic device. Furthermore, the present invention can be applied to a device in which the photographic recording system of a photographing device is replaced with a polaroid camera and the camera is automatically operated.

Since the present invention is configured as described above, it is possible to automate all or part of the manual operation of a diagnostic imaging device used for hard copying of various conventional computer-controlled medical diagnostic devices, and to reduce the labor and time required for hard copying. The aim is to reduce the amount of waste. In other words, using the computer that controls the above-mentioned medical diagnostic device, a sensor is installed to detect the operating status of each mechanism of the imaging device, and a combination machine monitors the status of each mechanism based on the signals from this sensor. It was designed to be controlled. This greatly reduces the effort and time required to make hard copies, especially when the diagnostic image storage device of the diagnostic device has a large capacity. Furthermore, when hard copying is performed at the same time as image data acquisition for diagnostic reasons, it is possible to provide a convenient device that can significantly improve the patient's clinical ability per unit time.
