Description
Technical field
The utility model belongs to the mobile field CT, and in particular to a kind of bus cable device of mobile CT.
Background technique
Plate CT is also known as CBCT i.e. Cone beam(pencil-beam) CT.As the term suggests being that pencil-beam throwing is disconnected according to computer recombination
Layer image equipment, principle are that X-ray emitter is surrounded with lower quantity of X-rays X (usual tube current is at 10-20 milliamperes or so)
It throws and does the digital throwing photograph of annular DR(according to body).Then it will surround and throw according to body repeatedly (360-720 times), after number throwing is shone in " intersection "
Data obtained " recombinate " afterwards in a computer and then obtain 3-D image.CBCT obtains the throwing of data according to principle and tradition fan
Shape scanning computed tomography is entirely different.
CBCT and body layer CT(spiral CT) maximum difference be that the data for projection of body layer CT is one-dimensional, the figure after reconstruction
As data be it is two-dimensional, the 3-D image of recombination is made of continuous multiple two dimension slicings accumulations, and image metal artifact is heavier.
And the data for projection of CBCT be it is two-dimensional, 3-D image is directly obtained after reconstruction.In terms of their imaging arrangement, CBCT is three-dimensional
Pencil-beam X-ray scanning replaces the two-dimensional sector-shaped beam scanning of body layer CT；Corresponding, CBCT is using a kind of two-dimentional planar detection
Device replaces the linear detector of body layer CT.
Cable fixed end is connected with rack during CT scan, and moved end and bulb, detector one act as rotary motion and realize in fact
When power supply with communicate, during this period cable need relatively determine motion profile and spatial dimension, do not allow freely to wind, by
It draws, it is safe and reliable to guarantee.Unlike spiral CT axial movement continuous rotation scanning, Cone-Beam CT is generally in synchronous belt
It under driving, only needs 360 degree of valid data of revolving scanning that can rebuild and obtains multiple faultage images, if power supply is adopted with communication mode
With carbon brush and low pressure slip ring, then cost is too high and function waste, if individually configuring in the synchronous pulley end face of scanning disk back side
Rotary type drag chain can then greatly increase scanning disk width, it appears complete machine is too fat to move.Though other excessively complicated wire laying modes can be full
The requirement of sufficient powered communication, but security risks, the actual effects such as that there are cables is at random, pulls, distorts are undesirable.
Summary of the invention
The purpose of the utility model is to provide the bus cable devices of mobile CT a kind of to be arranged by the way that cable to be arranged in winding displacement
