Embodiment 1

[0028] A bone age test instrument that scatters low-dose X-rays, such as figure 1 As shown, it includes a rack 1, an X image generating device, a control module 7, a scanning module 2, a driving module 8, a detection module 5, and a marking device 4. The X image generating device is arranged on the rack 1 and connected to the The scanning module 2, the control module 7 is connected to the X image generating device, the driving module 8 and the detection module 5, the identification device 4 is set on the detected human tissue, and the detection module 5 is set on the X image On the generating device, the detection module 5 is used to identify the identification device 4; the driving module 8 controls the scanning module 2 to scan and drives the X image generating device and the detection module 5 to move; the detection module 5 The distance between the identification device 4 and the identification device 4 is at least the length of the detected human tissue. When the detection...

Abstract

The invention discloses a bone age tester capable of scattering low-dose X-rays, which comprises a tester rack, an X image generator, a control module, a scanning module, a driving module, a detectionmodel, and a marking device, the X image generator is arranged on the tester rack and connected to the scanning module, the control module is connected to the X image generator, the driving module and the detection module, the marking device is arranged on a detected human tissue, the detection module is arranged on the X image generator, and the detection module is used for identifying the marking device. According to the bone age tester disclosed by the invention, as the detection module moves along with the scanning module, linear X-ray scanning is formed; moreover, only after the markingdevice is detected by the detection module can signals being fed back to the control module, the control module makes a judgment, if the detected human tissue is already completely scanned, then the scanning module makes a returning movement, returning to the initial position, consequently, the dose of X-rays is reduced, and X-ray radiation is decreased.

Description

Technical field [0001] The invention relates to the technical field of bone age meters, in particular to a bone age test instrument that scatters low-dose X-rays. Background technique [0002] Currently, accurate bone age testing generally requires X-ray imaging. Usually, a frontal X-ray film of the left wrist is taken. The doctor observes the development of the ossification center of the left palm phalanx, carpal bone and lower end of the radius and ulna through X-ray film to determine the bone age. At present, the most commonly used method for photographing bone age on the market is to use a digital tablet DR to take an orthographic X-ray of the human left wrist. Because this kind of machine is a general-purpose DR imaging system, one imaging during shooting will cause the patient's exposure dose to be too large. [0003] Using line scanning, the fan-shaped beam generated by the X-ray generator is converted into a narrow rectangular scanning beam through a slit. The driver modu...
