Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a portable radiological apparatus such as a mobile X-ray diagnostic apparatus or a mobile radiotherapy apparatus, which is different in a mode during movement and a mode during use. Hereinafter, a mobile X-ray diagnostic apparatus, specifically, a round X-ray apparatus will be described as an example.

[0002]

2. Description of the Related Art In a conventional device of this type, an arm for supporting an X-ray source is folded or positioned below, and the X-ray source is moved in a state where it is positioned at a predetermined moving position (moving mode). Also, extend or raise the arm,
The X-ray source has been used in a state where it is positioned at a predetermined position for use (form for use). In such an X-ray apparatus for rounds of visit, if the X-ray source is moved without using the moving mode (in use mode or in an intermediate form between them), the X-ray source may collide with something or be damaged during the movement of the device. There is a risk that the trolley portion of the device may be impaired and the device may fall over. In addition, X-rays do not always occur due to erroneous operation,
In this case, it will be harmful to the human body. This is particularly remarkable in the case of a cordless type X-ray apparatus for rounds. In the case of a cord-type X-ray apparatus for rounds, generally, X-rays are not generated unless a cord is connected to a power source, but in the case of a cordless-type X-ray apparatus for rounds, there is no such restriction, and X-ray generation This is because it is highly ad hoc. Further, if the device is used without being in the in-use form (in the moving form or an intermediate form between them), X-rays may be inadvertently generated and harm the human body. In order to deal with the above problems, the conventional device merely requires the user to transform the mobile phone into a form at the time of moving and then move the device, or to warn the user not to generate radiation during the move. However, no consideration was given to prohibiting the device itself from being used in a moving mode or being moved in a moving mode.

[0003]

Therefore, in the conventional apparatus, there is a risk that the apparatus may be moved in an unstable state during use, or radiation may be generated due to an erroneous operation even when the apparatus is moved, which is inadequate for safety. There were many points. In particular, it is dangerous for radiation to be generated accidentally or carelessly, and conventionally, improvement in this respect has been demanded.

It is an object of the invention of claim 1 to provide a portable radiation apparatus which is free from erroneous occurrence of radiation at least during movement and has improved safety.

In addition to the above object, the object of the invention of claim 2 is to prevent the accidental generation of radiation by disabling movement in the form in use, and also to prevent damage to the radiation source and fall of the apparatus. It is an object of the present invention to provide a portable radiation device which is further eliminated and has further improved safety.

[0006]

An object of the invention of claim 1 is to detect at least a moving form or a using form in a portable radiation apparatus having a moving form and a using form different from each other. This is achieved by providing a form sensor and a control means for prohibiting the generation of radiation in a form at the time of movement or a form other than the form in use by a signal from the form sensor. The form sensor detects at least a form during movement or a form during use. In addition, the control means prohibits the generation of radiation at least in a moving form or a non-using form by a signal from the form sensor. As a result, radiation error will not occur at least in the form at the time of movement or the form not at the time of use, and safety will be enhanced.

It is an object of the invention of claim 2 that the control means of the invention of claim 1 prohibits movement in a form in use or in a form other than a form of movement by a signal from the form sensor. Achieved by The shape sensor detects a moving shape, a using shape, and a shape that is neither of them. In addition, the control means prohibits the generation of radiation in a form during movement or a form other than the form during use by a signal from the form sensor. In addition, the control means also prohibits movement in a form in use or a form other than the form in movement. As a result, the radiation error in the non-use mode is eliminated, and the safety is improved. Also,
Since there is no movement in the non-moving form, inadvertent radiation generation is eliminated, and the possibility of damage to the radiation source and the fall of the device is reduced, and safety is further enhanced.

FIG. 1 is a configuration diagram showing an embodiment of a portable radiation apparatus according to the present invention. Here, a case where the present invention is applied to a cordless X-ray apparatus for rounds of medical examination, and a mode of use is shown. Figure 2 is the same as above X
It is a block diagram which shows the form at the time of movement of a line device. In FIG. 1 and FIG. 2, reference numeral 1 denotes an apparatus main body, which comprises a high voltage generator (not shown), a control circuit 1a, a form sensor 1b, an X-ray generation control circuit 1c, an apparatus movement control circuit 1d and the like. Reference numeral 2 is a carriage for mounting and fixing the apparatus main body 1 so as to be movable on the floor, and reference numeral 3 is an X-ray tube apparatus constituting an X-ray generation apparatus by the high voltage generation apparatus (not shown) and the control circuit 1a. 4 is an arm,

It is to be positioned.

The control circuit 1a controls the high voltage generator, the X-ray generation control circuit 1c, the device movement control circuit 1d, etc., and controls the X-ray generation and the device movement. The form sensor 1b detects whether the device is in use or in motion and gives a signal (detection signal) to the control circuit 1a. Further, the control circuit 1a constitutes a control means for inhibiting the generation of X-rays in the moving mode by the signal from the morphology sensor 1b together with the X-ray generation control circuit 1c, and the device movement control circuit 1d. A control means for prohibiting movement when the movement mode is not set is constituted by a signal from the shape sensor 1b. Here, the control circuit 1

Further, the device movement disapproval signal Sb1 is applied to, for example, a brake device (not shown) of the truck 2 to bring the brake into an actuated state or the brake cannot be released. Therefore, it is possible to prevent movement in the form in which it is being used, to prevent inadvertent X-ray generation,
In addition, damage to the X-ray tube device 3 and overturning of the device are prevented, and safety is further enhanced.

When the apparatus is moved, the X-ray tube apparatus 3 is positioned at the moving position by folding the arm 3 to the lower rear part as shown in FIG. At this time, the form sensor 1b detects that the arm 3 is folded to the lower rear part, that is, the device is in the form during movement, and a form detection signal during movement is given to the control circuit 1a. As a result, the X-ray generation non-permission signal Sa2 is output from the X-ray generation control circuit 1c, and the device movement permission signal Sb2 is output from the device movement control circuit 1d, respectively, and the X-ray generation is prohibited and the device movement is permitted. Be seen.
Specifically, the X-ray generation disabling signal Sa2 is given to, for example, the control circuit 1a and the X-ray tube device 3 to render them inoperable. Further, the device movement permission signal Sb2 is given to, for example, the above-mentioned brake device to bring the brake control operation state or the brake release impossible state. Therefore, erroneous X-ray generation during movement is eliminated.

In the present invention, the moving form means a state where the radiation source is positioned at a predetermined moving position, and the in-use form means a state where the radiation source is positioned at a predetermined using position. The specific forms of the moving form and the using form are not limited to the above-mentioned embodiments.
