Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mobile X-ray apparatus. In particular, the present invention relates to an X-ray apparatus that can perform an X-ray condition setting operation on the X-ray generation unit side.
[0002]
[Prior art]
The mobile X-ray device has a movable carriage 1 that is driven by a motor, a main body 2 installed on the carriage, an X-ray generator 3 that emits X-rays, and an X-ray generator 3 that is movable relative to the main body 2. Includes arm 4 to attach to. The X-ray generation unit 3 includes an X-ray tube device 31 and an X-ray diaphragm that limits the X-ray irradiation range.
[0003]
At the time of imaging, X-ray imaging of the subject is performed by moving the X-ray device to the bedside of the hospital room or operating room. At that time, the X-ray condition is set from the operation device installed at the rear of the main body 2. As shown in FIG. 4, the X-ray condition set by the operating device 10 is used as a command signal by the CPU 20 via the interface. Based on this command, a predetermined voltage is applied from the high voltage controller 21 to the X-ray tube device 31, and X-rays with the set conditions are irradiated.
[0004]
[Problems to be solved by the invention]
However, the conventional mobile X-ray apparatus has a problem in operability as follows.
[0005]
That is, at the bedside, the X-ray irradiation position is adjusted for photographing by grasping a handle attached to the X-ray apparatus main body, the X-ray generator or the arm. At this time, in order to set the X-ray condition, it is necessary to return to the operation device located at the rear of the main body and perform the operation, which is very troublesome for the operator.
[0006]
Accordingly, the main object of the present invention relates to a mobile X-ray apparatus capable of setting X-ray conditions without returning to the rear part of the X-ray apparatus main body.
[0007]
[Means for Solving the Problems]
The present invention achieves the above object by providing an operation device for setting X-ray conditions on the X-ray generation unit side as well.
[0008]
That is, the X-ray apparatus of the present invention is provided in the X-ray generator that irradiates X-rays, a main body that supports the X-ray generator via an arm, a movable carriage that runs the main body, and the X-ray generator. And an X-ray condition setting mechanism.
[0009]
Not only the body, in the X-ray generator side by providing the operating device for setting the X-ray condition, can be set X-ray condition in the X-ray generation unit side without returning to the operating device of the main body, at the same time X-ray irradiation position alignment can also be performed.
[0010]
In particular, there are two setting mechanisms: a first setting mechanism provided in the main body and a second setting mechanism provided in the X-ray generation unit , and any setting mechanism can be used to set X-ray conditions. Is preferred.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below.
FIG. 1 is a schematic diagram showing the overall configuration of the mobile X-ray apparatus of the present invention.
This X-ray apparatus includes a movable carriage 1 that is driven by a running motor, a main body 2 installed on the carriage, and an arm 7 that movably attaches an X-ray generation unit 3 to the main body.
[0012]
The mobile carriage 1 is provided with wheels that allow the X-ray apparatus to move, and the X-ray apparatus travels by driving the wheels with a motor or the like. The main body 2 has a built-in control mechanism for controlling the traveling motor and the X-ray generator 3. The X-ray generation unit 3 includes an X-ray tube device 31 and an X-ray diaphragm that limits the X-ray irradiation range. The main body 2 is provided with a rotatable support column 5, and an arm 7 is attached to the support column 5 via a slider 6 that can move up and down. The arm 7 can be bent in a joint shape, and the position of the X-ray generation unit 3 attached to the tip can be adjusted. A handle 8 is provided close to the X-ray tube device 31 so that the position of the X-ray generation unit 3 can be easily adjusted. Further, the X-ray generator 3 and the main body 2 are connected by a cable 9, and the X-ray generator 3 can be controlled by a control mechanism in the main body.
[0013]
At the time of imaging, the X-ray apparatus is moved to a predetermined location in the hospital where the subject is located, the X-ray tube apparatus is positioned, and then X-ray conditions are set and imaging is performed. The X-ray conditions include tube voltage, tube current, mAs value that is the product of tube current (mA) and time (sec).
[0014]
Here, two setting mechanisms (operators) can be used for setting the X-ray conditions. A first operation device 10 is provided on the upper surface of the rear portion of the main body, and a second operation device 11 is provided on the X-ray generation unit 3. The second operating device 11 is provided in the X-ray tube device 31, the arm 7 supporting the X-ray tube device 31, the X-ray diaphragm or in the vicinity thereof. Each of the operating devices 10 and 11 has a display panel on which X-ray conditions such as tube voltage, tube current, and mAs value are displayed.
[0015]
FIG. 2 shows a circuit block diagram of the control mechanism of the device of the present invention. The X-ray conditions set by the operation devices 10 and 11 are used as command signals by the CPU 20 via the interface. Based on this command, a predetermined voltage is applied from the high voltage controller 21 to the X-ray tube device 31, and X-rays with the set conditions are irradiated. At that time, even if the X-ray condition is set by any of the operating devices 10 and 11, the X-ray irradiation is performed under the set condition.
[0016]
In FIG. 1, when the X-ray condition is set by the first controller 10, the CPU 20 displays the set value of the tube voltage, the tube current, or the mAs value on the first controller 10. At the same time, a setting signal is input to the high voltage controller 21, and photographing can be performed under the setting conditions.
[0017]
When the X-ray condition is set with the second controller 11, the set values of the tube voltage, tube current, and mAs value are displayed via the CPU 20 in the same way as with the first controller 10. A signal is input to the voltage controller 10. At that time, the display on the first operating device 10 is also changed in the same manner as the second operating device 11.
[0018]
As described above, since the X-ray condition can be set by operating the second operating unit 11 installed in the vicinity of the X-ray tube device 31, the position of the first operating unit 10 is determined after the X-ray imaging is positioned. The trouble of returning to is eliminated.
[0019]
【The invention's effect】
As described above, according to the X-ray apparatus of the present invention, since the X-ray condition setting mechanism is provided in the X-ray generation unit, the X-ray condition can be set immediately after the imaging positioning operation. Will improve.
