BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a mobile radiographic apparatus, and more particularly, to a mobile radiographic apparatus that performs inspection of a subject based on X-ray.

Generally, a radiographic apparatus irradiates a radiation toward an object to be inspected, thereby obtaining relevant information of the object. Radiographic devices are used in a variety of industries. Among them, a radiographic apparatus used for medical purposes can acquire relevant information of the internal structure of the human body.

Background Art [0002] A conventional technique for a medical radiographic apparatus is disclosed in Korean Patent Laid-Open Publication No. 2010-0120597 (X-ray imaging apparatus, Nov. 16, 2010). The present invention relates to a radiographic apparatus installed in a hospital and used for a patient's treatment or treatment.

In driving such a radiographic apparatus, the patient is positioned to face the radiation source. The examiner enters a separate avoidance space that is shielded from the radiation source and proceeds with the patient's radiography based on the controller connected to the radiation source.

However, most of the mobile radiographing devices perform radiography for patients in a narrow space. Therefore, in the operation of the mobile radiographing apparatus, the examiner conducts radiography of the patient in a state adjacent to the radiation source. Accordingly, there has been a problem in that the dose of exposure of the examinee is increased in the operation of the mobile radiographic apparatus.

However, it should be understood that the present invention is not limited to the disclosed embodiments, but may be implemented in various forms, and the present embodiments are not intended to be exhaustive or to limit the scope of the invention to those skilled in the art. It is provided to let you know completely. The shape and the like of the elements in the drawings may be exaggerated for clarity, and the same reference numerals denote the same elements in the drawings.

FIG. 1 is a perspective view showing a mobile radiographic apparatus according to a first embodiment, and FIG. 2 is a block diagram showing a mobile radiographic apparatus according to a first embodiment.

As shown in FIGS. 1 and 2, the mobile radiographic apparatus 100 according to the first embodiment is transportable and can be moved to various inspection environments according to the purpose of inspection. That is, the photographing apparatus 100 is transferred to various environments such as a medical car and a sickroom in addition to the radiation room provided in the hospital, so that photographing can be performed based on radiation such as X-rays.

The photographing apparatus 100 may include a photographing unit 110, an input unit 130, and a control unit 150. [

First, the radiographic unit 110 radiates the radiation toward the subject to acquire relevant information of the subject. The photographing unit 110 may include a conveying unit 111, a supporting unit 112, a radiation emitting unit 113, and a light receiving unit 114.

The transfer unit 111 supports the components of the photographing unit 110 and can be provided by the inspector in a transportable manner. The transfer unit 111 can be supported by a plurality of rollers (not shown) in a rolling manner, and its position can be fixed in radiography.

The supporting part 112 is connected to the conveying part 111 so that the radiation emitting part 113 and the light receiving part 114, which can be arranged to face each other, For example, the support portion 112 may be provided in a bar shape, and the central region may be connected to the one side wall of the transfer portion 111 so as to be able to ascend and descend. Therefore, the support portion 112 can adjust the height of the radiation emitting portion 113 and the light receiving portion 114 according to the photographing portion of the subject.

Further, the support portion 112 can be pivoted relative to the conveying portion 111. [ Accordingly, the support portion 112 can change the angle between the radiation emitting portion 113 and the light receiving portion 114 at an angle set according to the photographed portion of the subject.

The radiation emitting portion 113 is disposed at one end of the supporting portion 112 and the light receiving portion 114 is disposed at the other end of the supporting portion 112 so as to face the radiation emitting portion 113. Here, the subject can be positioned between the radiation emitting portion 113 and the light receiving portion 114, and the interval between the radiation emitting portion 113 and the light receiving portion 114 can be adjusted.

For example, the radiation emitting portion 113 connected to the other end of the supporting portion 112 is linearly transportable along the supporting portion 112, so that the distance from the radiation emitting portion 113 can be adjusted. Thus, the shooting unit 110 can adjust the irradiation range and the scattering range of the radiation according to the adjustment of the interval between the radiation emitting portion 113 and the light receiving portion 114.

On the other hand, in the present embodiment, a configuration in which the radiation emitting portion 113 and the light receiving portion 114 are provided as a single structure by the supporting portion 112 is described. However, this is an embodiment for explaining this embodiment, and the radiation emitting portion 113 and the light receiving portion 114 may be provided separately.

On the other hand, the input unit 130 may include a controller 131. The controller 131 may be provided in a mechanical or electronic manner.

Here, the controller 131 generates an operation signal of the photographing unit 110 based on the input of the inspector. For example, the controller 131 can generate a signal related to the posture of the photographing unit 110 based on the input of the inspector. At this time, the control unit 150 may control the height and the rotation angle of the support part 112 and the interval between the radiation emitting part 113 and the light receiving part 114 based on the signal provided from the controller 131.

The controller 131 generates an emission signal related to the radiation emission time point based on the inspector's input. To this end, the controller 131 may be provided with a first input unit 131a and a second input unit 131b. Here, the first input unit 131a generates a first emission signal, and the second input unit 131b generates a second emission signal.

This input unit 130 is interlocked with the control unit 150 so that the related signal generated from the controller 131 is provided to the control unit 150. [ Here, the controller 131 may be provided in the photographing unit 110 itself or may be provided in a configuration separated from the photographing unit 110 so that a related signal is provided to the control unit 150 through a wired line. At this time, the controller 131 and the control unit 150 can be interlocked wirelessly, but it is preferable that the controller 131 and the control unit 150 interlock with each other in a radiation exposure environment in a wired manner.

On the other hand, the control unit 150 includes a control unit 151 that can be provided in the photographing unit 110 or the input unit 130. [ The control unit 151 allows the photographing unit 110 to be controlled based on the related signal provided from the input unit 130. [

First, the control unit 151 controls the height and the rotation angle of the support unit 112 and the interval between the radiation emitting unit 113 and the light receiving unit 114 according to the operation signal when the operation signal is supplied from the controller 131 . When the emission signal is provided from the controller 131, the control unit 151 may change the radiation emission time from the radiation emitting unit 113 according to the emission signal.

If the first emission signal is provided from the controller 131, the control unit 150 can control the radiation emitting portion 113 so that the radiation from the radiation emitting portion 113 is immediately emitted.

If the second emission signal is provided from the controller 131, the control unit 150 controls the radiation emitting portion 113 so that the radiation emission from the radiation emitting portion 113 is made after a predetermined time have. For example, when the second emission signal is provided from the controller 131, the control unit 150 may cause radiation to be emitted from the radiation emitting portion 113 after 4 to 6 seconds from the input time of the inspector.

Accordingly, the inspector can leave the inspection position for a predetermined time after the controller 131 is input. That is, the radiographic apparatus 100 can delay the radiation emission time point, so that the radiation can be emitted from the radiation emitting unit 113 after the inspector releases the inspection position. Thus, the inspector can be assured of safety from exposure even in repeated radiation examinations.

That is, when the inspection is performed in the radiation room provided in the hospital, the inspector may enter the separate avoiding space blocked by the radiation emitting unit 113 to control the radiation emitting unit 113. Thus, the inspector can be safe from exposure due to radiation emission.

However, the mobile radiographic apparatus 100 may be moved to various environments without a separate avoiding space and may be inspected. Therefore, the inspector can not be free from radiation exposure.

However, in the case of the photographing apparatus 100, the radiation emission time can be delayed so that the inspector can secure time to avoid the inspection position after the controller 131 is input. Thus, the inspector can be safe from exposure even in repeated tests.

However, the present embodiment describes an embodiment in which the photographing apparatus is driven at an inspection position where no separate avoiding space is provided. However, this is only one example for explaining the present embodiment, and it is not limited to the inspection position and can be applied to an environment provided with a separate avoiding space.

Hereinafter, a mobile radiographic apparatus according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. However, the same reference numerals are given to the components described above.

3 is a flowchart showing a driving method of the mobile radiographic apparatus according to the first embodiment.

3, the photographing apparatus 100 according to the first embodiment can be moved to an inspection position where an inspected object (hereinafter, referred to as a patient) is located (S100). Here, the examination position may be a narrow environment such as a medical examination room and a hospital room.

Then, the examiner fixes the photographing apparatus 100 and performs a radiographic examination on the patient. At this time, the inspector can manipulate the controller 131 according to the examination region of the patient to change the posture of the support 112 (S200).

For example, when the patient's chest is inspected, the height of the support portion 112 is adjusted to a height corresponding to the chest position of the patient, so that the opposite direction of the radiation emitting portion 113 and the light receiving portion 114 is parallel to the plane (See FIG. 4). At this time, the patient can be positioned between the radiation emitting portion 113 and the light receiving portion 114, and the inspector can adjust the distance between the radiation emitting portion 113 and the light receiving portion 114 to adjust the irradiation range and the scattering range of the radiation have.

When inspecting the arm of the patient, the height of the support portion 112 may be adjusted to a height corresponding to the arm position of the patient, and the opposite direction of the radiation emitting portion 113 and the light receiving portion 114 may be adjusted to cross the plane (See FIG. 5). At this time, the patient places the arm between the radiation emitting portion 113 and the light receiving portion 114, and the inspector adjusts the distance between the radiation emitting portion 113 and the light receiving portion 114 so as to adjust the irradiation range and the scattering range of the radiation have.

Thereafter, the inspector operates the controller 131 so that the radiation is emitted from the radiation emitting portion 113. Here, the inspector can selectively operate the first input unit 131a or the second input unit 131b according to the inspection environment and the situation (S300).

For example, when the inspector operates the first input unit 131a, the controller 131 generates the first emission signal, and the control unit 150 outputs the first emission signal from the radiation emitting unit 113 in accordance with the first emission signal. (S310).

When the inspector operates the second input unit 131b, the controller 131 generates the second emission signal, and the control unit 150 controls the emission of radiation from the radiation emitting unit 113 in accordance with the second emission signal The predetermined time may be performed later (S320).

For example, the control unit 150 may cause radiation to be emitted from the radiation emitting portion 113 after 4 to 6 seconds from the input time of the inspector's second input portion 131b. Thus, the inspector can avoid a safe position from the inspection position between the input time point of the second input unit 131b and the radiation emission point, and can be safe from radiation exposure.

Hereinafter, a mobile radiographic apparatus according to another embodiment will be described in detail with reference to the accompanying drawings.

FIG. 6 is a perspective view showing a mobile radiographic apparatus according to a second embodiment, and FIG. 7 is a block diagram showing a mobile radiographic apparatus according to a second embodiment.

6 and 7, the photographing apparatus 200 according to the second embodiment may further include a sensor unit 132 configured to allow the input unit 130 to sense an inspection position of the inspector.

Here, the sensor unit 132 may be provided outside the photographing unit 110 or the photographing apparatus 100. The sensor unit 132 may provide the position signal of the inspector from the control unit 150 so that the radiation emission time from the radiation emitting unit 113 is changed.

More specifically, the photographing apparatus 100 according to the first embodiment causes radiation to be emitted after approximately four to six seconds have elapsed from the input time of the examiner's second input section 131b. However, the inspector can not be free from radiation exposure if the inspector does not avoid within a predetermined time from the inspection location, depending on the situation.

However, the photographing unit 110 according to the second embodiment can further delay the radiation emission time point according to the position signal of the inspector provided from the sensor unit 132 by the control unit 150. [

For example, when the inspector operates the second input unit 131b, the control unit 150 stops the emission of radiation from the radiation emitting unit 113 when the inspector is located at the inspection position. When the inspector leaves the inspection position, the control unit 150 causes the radiation to be emitted after a predetermined period of time, for example, 4 to 6 seconds, has passed from the departure point of the inspector in accordance with the signal provided from the sensor unit 132 .

That is, the photographing unit 110 according to the first embodiment can cause the radiation to be emitted after a predetermined time has elapsed from the time of operating the second input unit 131b of the inspector. However, the photographing unit 110 according to the second embodiment can cause the radiation to be emitted after a predetermined time has elapsed from the inspection position departure time of the inspector after the operation of the second input unit 131b of the inspector.

On the other hand, the controller 131 according to the second embodiment can change the delay time based on the input of the inspector. For example, the present embodiment describes that the radiation is emitted after 4 to 6 seconds have elapsed from the time of departure of the inspector. However, the inspector can manipulate the controller 131 to adjust the delay time.

For example, when the controller 131 is provided mechanically, the inspector can operate the time control unit 131c, which may be provided in the form of a switch before or after the operation of the second input unit 131b. At this time, the controller 151 may decrease or increase the delay time according to the time control signal generated by the controller 131. [

When the controller 131 is provided electronically, the inspector can operate the time control unit 131c output on the controller 131 before or after the operation of the second input unit 131b. At this time, the controller 151 may decrease or increase the delay time according to the time control signal generated by the controller 131. [

As described above, the mobile radiographic apparatus according to the present invention has an effect that the safety of the inspector is improved by reducing the exposure dose of the inspector, and the radiation emission time point is adjusted depending on the case, so that it can be applied to various inspection environments and conditions.

One embodiment of the invention described above and shown in the drawings should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention in various forms. Accordingly, such improvements and modifications will fall within the scope of the present invention as long as they are obvious to those skilled in the art.
