Patent Description:
Three-dimensional DR mainly includes an X-ray generator, a flat panel detector and an image process workstation. Three-dimensional DR can be applied in the medical field, three-dimensional DR technology can provide reconstruction images or image groups of the scanned patient's tomography. The reconstructed image or image group includes all the image information in the three-dimensional space of the scanned area of the patient, the doctor can acquire the patient's tomography, sagittal section, coronal section or information of any point of the three-dimensional space to assist the diagnosis. Besides, the three-dimensional DR can also be supplied in the archaeology field to provide a three-dimension image of the relic for acquiring a more specific information, thus the three-dimensional DR has a wide range of applications in the field of fluoroscopy, spot film photography and various kinds of angiography.

In the related technologies, when the patient, relic or other stuff need a scanning imaging, the scanned objects are sent to the three-dimensional DR device for a three-dimensional scanning imaging. While some of the relics cannot be moved, so that instead of being sent to the three-dimensional DR device for a three-dimensional scanning imaging, the relics can just be simply captured for observation. Besides, when the doctor goes to the countryside to diagnose and treat patients or goes to the disaster area to support, some patients are in serious condition, and cannot be transferred to the three-dimensional DR device for three-dimensional imaging to observe the condition, which is not convenient for doctors to make timely treatment.

Two ends of the moving pole <NUM> is connected with a moving panel <NUM> through the screw, and the two moving panels <NUM> are relatively arranged in parallel. A guide rod <NUM> is provided between the two moving panel <NUM>, the quantity of the guide rod <NUM> in this embodiment is two and the two guide rods <NUM> are parallel. The adjusting component <NUM> further includes a baffle <NUM>, the quantity of the baffle <NUM> in this embodiment is two, one of the baffles <NUM> is connected with the moving panel <NUM> through the screw, another baffle <NUM> is slidingly connected with the guide rod <NUM> by being passed through by the guide rod <NUM>, and the baffle <NUM> is slid in the direction of closing to or far from the another baffle <NUM>. The guide rod <NUM> is further provided with a fixing panel <NUM>, this embodiment is in a screw connection. The moving panel <NUM> is further provided with an adjusting bolt <NUM> for adjusting the sliding distance of the baffle <NUM>, and an end of the adjusting bolt <NUM> far from a nut is sequentially passed through the moving panel <NUM> and the baffle <NUM>, and the adjusting bolt <NUM> is rotataly connected with a side of the fixing panel <NUM>, the baffle <NUM> is threadedly connected with the adjusting bolt <NUM>. The adjusting bolt <NUM> can be rotated to slide the baffle <NUM> on the guide rod <NUM>. A limiting panel is integrally formed on the baffle <NUM>, the flat panel detector <NUM> is provided between the two baffles <NUM> and is attached to the limiting panel <NUM>.

The implementation principle of the embodiment <NUM>: when using the portable three-dimensional DR system, the support tube <NUM> is placed on the horizontal plane, then the cover <NUM> of the mounting box <NUM> is opened to place the locking pin <NUM> in the locking hole <NUM>, the mounting box <NUM> is connected to the mounting platform <NUM>, and then the mounting cover <NUM> is opened to adjust the position of the X-ray generator <NUM>, which is convenient to scan and photograph the human body or the object.

The length of the telescopic foot <NUM> is adjusted and the telescopic foot <NUM> is placed on the horizontal plane, then the adjusting screw is rotated to place the flat panel detector <NUM> between the two baffle <NUM>, and the adjusting screw is rotated again so that the two baffles <NUM> are attached with the flat panel detector <NUM> for fixing the flat panel detector <NUM>. Then the rotary pole <NUM> is rotated to slide the moving pole <NUM> on the stand body <NUM>, the height of the flat panel detector <NUM> is adjusted to improve the scope of application.

Lastly, the human body or the object is placed in front of the flat panel detector <NUM>, then the transmission component <NUM> is controlled through the computer by the worker to drive the X-ray generator <NUM> to repeatedly move in the direction of closing to or far from the support tube <NUM>, meanwhile, the X-ray generator <NUM> is driven by the drive component <NUM> to rotate, so that the human body or the object is convenient to be scanned and photographed.
