The medical image tooth X-ray photography positioning support, including support body, chin support, support rod, listen to nose line mark post and listen to the mouth line mark post, support body is equipped with support rod, and support rod is connected with support body through the axle seat, and it is perpendicular to support body, the upper end of support rod is equipped with telescopic rod perpendicularly, and the telescopic rod end is welded with calibration frame telescopic rod perpendicularly, and the calibration frame telescopic rod bottom end is welded with upper and lower jaw scale, and the one side of support body is equipped with chin support. Its beneficial effect is: the medical image tooth X-ray photography positioning support of the utility model can assist patient when shooting, and quickly and accurately finds corresponding position, can be applicable to all kinds of crowd use, improves the work efficiency and accuracy of shooting, and brings the convenience to doctor and patient. But since the X-ray machine needs to detect object vertically and emit X-rays, when detecting object is not parallel to the horizontal plane, only the calibration rod that can vertically extend can be used, and it is difficult to guarantee the detection accuracy of the X-ray machine. SUMMARY

[0004] In order to solve the problem of inaccurate detection when the detection object is not parallel to the horizontal plane, the application provides a mobile X-ray machine with a collimation function.

[0005] The mobile X-ray machine with a collimation function provided by the application adopts the following technical scheme:

[0006] A mobile X-ray machine with collimation function includes a machine head, a rangefinder, a flat panel detector, and a support frame. The machine head is equipped with an X-ray tube for X-ray detection. The rangefinder is fixedly connected to the machine head and includes multiple rangefinder modules. The signal emission direction of each rangefinder module is the same and perpendicular to the X-ray emission direction of the X-ray tube. The flat panel detector is separately disposed from the rangefinder and can reflect the signals emitted by the rangefinder modules to control the orientation of the X-ray tube. The support frame includes a rotating shaft that connects the rangefinder and the support frame, allowing the machine head and the rangefinder to rotate relative to the support frame.

[0007] By adopting the above technical solution, the machine head is equipped with an X-ray tube, which serves as both an X-ray emitting and receiving device. Therefore, during X-ray tube detection, it is necessary to ensure that the machine head is perpendicular to the object being measured to maintain accurate X-ray detection. The rangefinder is fixedly connected to the machine head, allowing the machine head to adjust its relative position via the rangefinder. The rangefinder transmits signals to the flat panel detector through multiple ranging modules and receives return signals. By comparing the distance differences measured by different ranging modules, it is determined whether the ranging modules and the flat panel detector are parallel. When the detected distances of all ranging modules are the same, it can be determined that the rangefinder and the flat panel detector are parallel. The X-ray machine is designed to determine the X-ray irradiation angle using a flat panel detector. The flat panel detector is separate from the rangefinder, making its placement easy to control and allowing for simple direction control of the X-rays. When the object to be measured is placed on a non-horizontal plane, the flat panel detector can also be positioned on a non-horizontal plane to adjust the orientation of the rangefinder and the X-ray tube, ensuring the X-ray tube is perpendicular to the object. The support frame controls the orientation of the X-ray tube via a rotating shaft. When the position of the object to be measured is not perpendicular to the orientation of the X-ray tube, the orientation can be adjusted via the rotating shaft, making the X-ray machine suitable for different scenarios and increasing its applicability.

[0008] Optionally, a mobile cart is also included, which is connected to the support frame.

[0009] By adopting the above technical solutions, the mobile vehicle can make it easier to move the X-ray machine. By connecting the support frame, the mobile vehicle can move the entire X-ray machine. The mobile vehicle can be equipped with a drive system to move X-ray machines with large mass, making the movement of the X-ray machine more convenient.

[0010] Optionally, the support frame may also include a telescopic pole that connects the mobile vehicle and the frame of the support frame.

[0011] By adopting the above technical solution, since the mobile vehicle has a limited range of movement and is difficult to move to a suitable position in some scenarios, the addition of a telescopic pole allows the X-ray machine to have a larger imaging range, which helps to improve the applicability of the X-ray machine.

[0012] Optionally, the support frame further comprises a sliding rail and a sliding block, the sliding block being capable of sliding in the sliding rail, and the sliding block being connected to the rotating shaft.

[0013] By adopting the above technical scheme, the sliding rail and the sliding block on the support frame can drive the head to move along the extension direction of the sliding rail, so that the head can be adjusted in position under the condition that the X-ray machine is fixed, thereby improving the applicability of the X-ray machine.

[0014] Optionally, the number of distance measuring modules is four, and the distance measuring modules are distributed in a square shape.

[0015] By adopting the above technical scheme, since the distance measuring instrument measures the distance between the distance measuring modules and the flat panel detector and judges whether the distance measuring instrument and the flat panel detector are parallel, by limiting the number of distance measuring modules to four and distributing the distance measuring modules in a square shape, the entire plane of the distance measuring instrument is parallel to the flat panel detector, thereby improving the control head performance of the distance measuring instrument.

[0016] Optionally, the flat panel detector is provided with a protective pad.

[0017] By adopting the above technical scheme, since the flat panel detector needs to be placed on the ground or other flat surfaces where objects are placed frequently, the protective pad can prevent scratches and wear on the flat panel detector during placement, and also facilitates the operator to place and remove the flat panel detector.

[0018] Optionally, the mobile vehicle further comprises a locking frame.

[0019] By adopting the above technical scheme, since the stability of the head needs to be ensured during use of the X-ray machine, the locking frame is provided to support the ground when the X-ray machine is fixed, so as to prevent the mobile vehicle from moving due to the rolling of the wheels, thereby ensuring the stability of the X-ray machine during detection.

[0020] Optionally, the mobile vehicle further comprises an operation table and a display screen.

[0021] By adopting the above technical scheme, the operation table and the display screen are provided, so that the X-ray machine can be quickly and simply operated through the operation table, and the working state of the X-ray machine can be understood in time through the display screen, which is beneficial to improve the efficient interaction performance of the X-ray machine.

[0022] In summary, the present application has at least one of the following beneficial technical effects:

[0023] 1. The distance measuring instrument and the head are fixedly connected, when the detected distances of multiple distance measuring modules are the same, it can be judged that the distance measuring instrument and the flat panel detector are in parallel state, so as to realize the determination of the irradiation angle of X-ray through the flat panel detector, and the flat panel detector is separately arranged with the distance measuring instrument, easy to control the placement position, and the direction control of X-ray can be realized more simply; the rotating shaft can adjust the orientation of the head, so that the X-ray machine can be suitable for different scenes, and the applicability is increased;

[0024] 2. The telescopic rod enables the X-ray machine to have a larger shooting range, which is beneficial to improve the applicability range of the X-ray machine, the slide rail and the sliding block can drive the head to move along the extension direction of the slide rail, so that the head can adjust the position under the condition that the X-ray machine is fixed, so that the X-ray machine has a larger shooting range and improves the applicability.
