Abstract
The invention provides a CT imaging system. According to the technical scheme, by improving the structure of an X-ray receiving device, the receiving capacity of the device is improved, the pixel of the device is refined, therefore, normal imaging of the CT imaging system cannot be influenced even though certain relative displacement exists between the X-ray receiving device and a receiving device, and the signal-to-noise ratio is higher; on the basis of the technical advantages, a traditional CT device is redesigned, the detection part of the CT device is greatly simplified, whole body scanning can be conducted on a detected person only by depending on mechanical motion of a rotating arm and a telescopic arm, therefore, the equipment structure is simplified, the whole cost is reduced, and meanwhile the detection time is shortened. The CT imaging system achieves the outstanding technical effects in a relatively simple structure mode, is easy to achieve and controllable in cost, has the obvious technical advantages and has the high popularization prospect.
Description
Technical field
The present invention relates to video diagnostic technology field, be specifically related to a kind of CT imaging system.
Background technology
CT detection, as a kind of diagnostic imaging method of routine, accounts for diagnostic imaging total amount in clinical practice
70%, its universality and effectiveness are self-evident.
The CT imaging system of prior art can be divided into two classes, a class to use flat board to visit according to its detector classification
Surveying device, its each sensing unit has been arranged in the two-way array of a bidimensional, when diagnosis film making, the most directly
Obtain the plane picture that a width is made up of picture element matrix；Another kind of is that slit X-ray scanning detects with linear array
The method of device combination, linear array detector is the one dimensional linear array detection that detection sensing unit has been arranged in straight line
Device, it to match with scanning motion just can obtain the image of a width bidimensional.Linear array detector has makes an uproar without background
Sound, radiation dose are low, wide dynamic range, density resolution high, the advantage of low cost of manufacture, therefore obtain
More it is widely applied.
The CT imaging device of prior art is in order to ensure the accuracy of detection, it is desirable to X-ray emission portion, reception
The cell position such as portion, tested human body is accurately fixed, so devise more greatly, more complicated frame for movement, it leads to
Norm formula is as shown in Figure 1, the most relatively costly in this case, and equipment quality, volume are relatively big,
Time and step needed for performing one-time detection the most relatively cumbersome simultaneously.If but simplifying device structure, often
It is difficult to meet the agreeing with property requirement of X-ray emitter and receptor.
Summary of the invention
It is contemplated that for the technological deficiency of prior art, it is provided that a kind of CT imaging system, it is being effectively ensured
CT imaging system complicated in mechanical structure, detecting step in prior art is solved on the basis of X-ray transmitting-receiving efficiency
Loaded down with trivial details technical problem.
For realizing above technical purpose, the present invention by the following technical solutions:
A kind of CT imaging system, it is characterised in that: include fixed rack, turning arm, the first telescopic arm, the
Two telescopic arms, X-ray emitter, X-ray receptor, motor, monitor station, signal processor, display screen,
Wherein signal processor passes through connection with display screen, X-ray receptor respectively, and motor is connected to fixed station
Inside frame, turning arm is connected to motor lower end, the first telescopic arm and the second telescopic arm and lays respectively at turning arm two ends
And downwardly extend, X-ray emitter is fixedly connected on the first telescopic arm lower end, and X-ray receptor is fixing to be connected
In the second telescopic arm lower end, monitor station fixed in position is below turning arm；Meanwhile, described X-ray receptor
Including main substrate and some probe units of being uniformly fixed on main substrate, each probe unit includes crystal and light
Electric diode, the receiving plane of photodiode fits with crystal face, each identical row in probe unit direction
Row and be parallel to X-ray with the receiving plane of photodiode, the direction that is perpendicular to main substrate is fixed on main base
On plate.
Preferably, also include that stereotype, described stereotype are fixedly connected on the photodiode end face of each probe unit
On.
Preferably, described motor position stepper motor.
Preferably, the brachium adjustable of described turning arm.
Preferably, the center of rotation adjustable of described turning arm.
In above technical scheme, telescopic arm possesses upper and lower Telescopic, and performs during expanding-contracting action first and stretch
Arm and the second telescopic arm synchronize, same distance is stretched, and fix with both guarantees position relatively and then ensure that signal is received
That sends out is smooth and easy.The effect of stereotype is intended to stop that x-ray bombardment on photodiode, thus avoids interference.
In the main technical schemes of the present invention, improved by the structure that X-ray is received device and improve it
Receiving ability, refine pixel so that even if X-ray emission device and receiving exists certain between device
Relative displacement does not interferes with its normal imaging yet, and signal to noise ratio is higher.Based on this technical advantage, to traditional CT
Device is redesigned, and enormously simplify the probe portion (i.e. signal transmitting and receiving relevant portion) of CT device,
The mechanical movement only relying on turning arm and telescopic arm can perform body scan to detected person, thus simplify and set
Standby structure, reduce holistic cost and shorten the detection time simultaneously.
In optimal technical scheme: set up stereotype be intended to stop x-ray bombardment on photodiode, thus
Avoid interference；It is to meet in some cases, needing to fix certain several accurately that motor is defined to stepper motor
Position performs the testing requirement of scanning；The adjustable in length limiting turning arm allows for object under test size not
Same or that partial x-ray discharger coverage is different situations；The center of rotation limiting turning arm is adjustable
The whole facilitation being easy for detection, can arbitrarily adjust.
The present invention achieves prominent technique effect with relatively simple structural models, and be easily achieved, cost controlled,
There is obvious technical advantage, great promotion prospect.
