The pressure used as a reference for determining the change in pressure may be a pressure at the start of the X-ray imaging. In addition, it may be an average value of the pressure from the start of the X-ray imaging until a predetermined time elapses. However, it is not limited thereto, and various values that can represent the existing pressure values may be selected.

In addition, it is preferable that the pressure sensing unit 160 acquires a pressure applied to at least one of the bib 161, the temple support 162, and the bite block 163.

In addition, it is possible to obtain a pressure applied to a plurality of means of the patient alignment means. In this case, it is also possible to determine whether the change in pressure deviates from a predetermined reference range 200 by combining the pressures applied to the plurality of means by an average or weighted average, or the pressure applied to the plurality of means It is also possible to determine whether or not the change in each pressure deviates from the predetermined reference range 200 by setting a priority among them.

Furthermore, the pressure sensing unit 160 may include a pressure sensor.

5 is a flowchart illustrating an X-ray imaging method according to an embodiment of the present invention. As shown in FIG. 5, the reference range 200 includes an increase limit 210 of the pressure and a drop limit 220 of the pressure, and determining whether or not the reference range 200 is deviated. In (S200), it is preferable to determine whether the pressure has risen above the rising limit 210 and whether the pressure has fallen below the falling limit 220.

In addition, FIG. 6 is a schematic diagram for explaining an X-ray imaging method according to an exemplary embodiment of the present invention. As shown in FIG. 6 (a), the reference range 200 is a rising limit 210 exceeding the reference pressure by a predetermined value, a falling limit 220 falling below the reference pressure by a predetermined value, And it may be made of values between the rising limit 210 and the falling limit 220.

It is preferable that the rising limit 210 and the falling limit 220 are selected as appropriate values capable of detecting an abnormal operation of the examinee 400. For example, it may be selected as a value corresponding to 150% and 50% of a pressure (reference pressure) that is a reference for determining the change in the pressure.

In addition, the X-ray imaging method according to an embodiment of the present invention may include determining whether the X-ray can be resumed when it is determined that the pressure has risen above the rising limit 210 (S400); And when it is determined that the X-ray imaging can be resumed, restarting the X-ray imaging (S500).

When it is determined that the pressure has risen above the rising limit 210, a warning may be sent to at least one of the examinee and the operator of the X-ray imaging apparatus 100. As the warning means, any one or more of an alarm and acoustic means such as voice guidance, a visual means such as flash or guidance text, and a tactile means such as vibration may be used.

In addition, the step of determining whether the resumption is possible preferably includes a step of determining whether the pressure has returned below the rising limit 210. In this case, it is also desirable to provide a hysteresis section for the pressure for stable shooting control.

That is, if the pressure increases, since the body of the examinee 400 does not deviate from the alignment means, when the pressure returns to below the rising limit 210, it is meaningful to resume the photographing continuously with the existing photographing. have. In this case, it is difficult to say that it is an emergency situation, and shooting can be resumed only by the examinee 400 recovering proper attention.

In addition, the X-ray imaging apparatus 100 includes a gantry 140 that rotates during the X-ray photographing, and the step of stopping the X-ray photographing includes a process of stopping the rotation of the gantry 140, and the X-ray Resuming photographing is a process of restarting rotation of the gantry 140 from a position at which rotation of the gantry 140 is stopped or a position retracted by a predetermined angle from a position at which rotation of the gantry 140 is stopped. It is preferable to include.

As such, by stopping the rotation of the gantry 140 or restarting the rotation at a position retroactively by a predetermined angle, unnecessary re-photographing may be prevented and the amount of X-ray exposure of the examinee may be reduced.

The angle at which the gantry 140 rotates backward may be selected as an appropriate angle so as not to cause a frame of image data to be damaged. For example, it is possible to select from 1 to 5 degrees.

In addition, when recording is resumed by moving the gantry 140 backward as described above, image data (projection data) generated by converting an electrical signal generated by the sensor unit 120 may be duplicated. The redundant data may be basic information for determining whether the posture of the examinee 400 has changed compared to before stopping the photographing.

In another embodiment of the present invention, the change information of the posture of the examinee 400 is obtained from the overlapping data, and the image data is corrected based on the change information, such as stitching or reconstruction. By proceeding to the image generation step, a higher quality X-ray image may be obtained.

In addition, the X-ray imaging method includes: when it is determined that the pressure falls below the lowering limit 220, determining whether an input for resuming the X-ray imaging is received from the outside (S600); And when the input is received, resuming the X-ray imaging (S700).

When the pressure falls below the lowering limit 220, there is a high possibility that an emergency situation occurs in the examinee 400 and the alignment means has been deviated. Therefore, in this case, it is preferable to stop photographing once and resume photographing when there is an input instructing to resume photographing from the outside.

In addition, in addition to the input instructing to resume shooting, whether to resume shooting at a position where the gantry 140 previously stopped shooting or a position retracted by a predetermined angle from the stopped position, or whether to resume shooting before stopping shooting It is also possible to input whether or not to retake from the start position of.

In another embodiment of the present invention, unlike FIG. 5, when the absolute value of the change rate exceeds a first reference value by detecting a rate of change in which pressure changes over time, X-ray imaging may be stopped. In this case, in order to properly calculate the rate of change, the pressure data may be pre-processed using a noise removing means such as a real-time low pass filter.

In this embodiment, the reference range 200 may be selected as the first reference value, a value obtained by multiplying the value of the first reference value by -1, and a change rate value therebetween.

In particular, when the absolute value exceeds a second reference value that is greater than the first reference value by a predetermined value, it may be determined that an emergency situation has occurred. This is because the examinee 400 may abruptly leave the X-ray imaging apparatus 100 or collide with the X-ray imaging apparatus 100. In this case, it is preferable to stop X-ray imaging and wait to receive an instruction to resume imaging from the outside.

When the absolute value exists between the first reference value and the second reference value, it is possible to resume once the photographing is stopped when the absolute value falls below the first reference value. In this case, it is also desirable to provide a hysteresis section for the pressure for stable shooting control.

It is preferable that the first reference value and the second reference value be selected as appropriate values capable of detecting an abnormal operation of the examinee 400. For example, the first reference value may be selected as (1% of the reference pressure)/second, and the second reference value may be selected as (2%/second of the reference pressure).

An X-ray imaging apparatus 100 of the present invention for achieving the above object includes: an imaging unit 170 for photographing X-rays of the examinee 400; A pressure sensing unit 160 for acquiring a pressure applied from the examinee 400 while the photographing unit 170 performs the X-ray imaging; And a control unit 150.

The control unit 150 determines whether the acquired pressure change deviates from a predetermined reference range 200, and when it is determined that the pressure change deviates from the reference range 200, the photographing It is preferable that the unit 170 controls the X-ray to stop.

In addition, the X-ray imaging apparatus 100 further includes a bib 161, a temple support 162, and a bite block 163, and the pressure sensing unit 160 includes the bib 161, the temple support ( It is preferable to obtain a pressure applied to at least one of 162) and the bite block 163.

In addition, when it is determined that the pressure has risen above the rising limit 210, the controller 150 determines whether the X-ray can be resumed, and when it is determined that the X-ray can be resumed, the photographing It is preferable to control the unit 170 to resume the X-ray imaging.

Meanwhile, the controller 150 may determine whether the X-ray can be resumed, including a process of determining whether the pressure has returned below the rising limit 210.

In addition, the photographing unit 170 includes a gantry 140 that rotates during the X-ray photographing, and the gantry 140 stops rotating when the X-ray photographing is stopped, and the controller 150 , When the photographing unit 170 controls to resume the X-ray photographing, from a position at which rotation of the gantry 140 is stopped or a position backward by a predetermined angle from a position at which rotation of the gantry 140 is stopped It is preferable to resume rotation of the gantry 140.

In addition, when it is determined that the pressure has fallen below the lowering limit 220, the controller 150 waits to receive an input instructing the resumption of the X-ray imaging from the outside, and receives the input. It is preferable to control the photographing unit 170 to resume the X-ray photographing.
