Embodiment Construction

[0028] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] First, please refer to image 3 , image 3 It is a schematic diagram of the first embodiment of the device and method for forming X-ray flying spots of the present invention. image 3 The middle is the case where only the transmission detector receives the X-ray signal. Such as image 3 As shown, the ray source collimator 11 is a linear slit collimator, located between the ray source 10 and the rotating shaft 12, the X-ray 20 emitted by the ray source 10 passes through the linear slit collimator 11 and forms a fan shape, and the rotating shaft 12 There are at least two spiral grooves 13 on it, the depth of the spiral groove 13 is enough to transmit X-rays 10, and the transmitted X-rays 10 form a monotonous rise or fall with the rotation of the rotation axis, the purpose is to make the straight line slit collimated After the X-ra...

Abstract

The invention provides a device and a method for forming an X-ray flying spot. The device comprises a ray source, a ray source collimator and a rotating shaft, wherein the ray source collimator is positioned on a beam output window of the ray source; and the rotating shaft is positioned at one side of the ray source collimator and is at least provided with two circles of spiral grooves. The device also comprises a time circuit breaker which is positioned at one side of the rotating shaft, from which beams are output. According to the device and the method for forming the X-ray flying spot which are disclosed by the invention, the time circuit breaker is matched with the rotating shaft provided with a plurality of circles of spiral grooves, so that the pitch range of X ray is widened. In addition, only one X-ray beam can be ensured to pass at any moment, and thus the stability of the device is improved.

Description

technical field [0001] The invention relates to an X-ray imaging technology, and in particular to a device and method for forming X-ray flying spots. Background technique [0002] In the prior art, the closest to the technology provided by the present invention is a patent titled "Apparatus and Method for Forming X-ray Flying Spots", please refer to figure 1 , figure 1 It is a schematic structural diagram of a device for forming X-ray flying spots in the prior art, such as figure 1 As shown, the ray source collimator 11 is a linear slit collimator, located between the ray source 10 and the rotating shaft 12, the X-ray 20 emitted by the ray source 10 passes through the linear slit collimator 11 and forms a fan shape, and the rotating shaft 12 There is a helical groove 13, the depth of the helical groove 13 is enough to transmit the X-ray 10, and the transmitted X-ray 10 forms a monotonous rise or fall with the rotation of the rotation axis, the purpose is to make the X-ray ...
