Abstract
The invention provides a suspended type X-ray shooting system, which comprises a system main controller, a detector and a bulb tube, wherein a first gyroscope sensor is arranged on the detector, a second gyroscope sensor is arranged on the bulb tube, and the first and the second gyroscope sensors are connected with the main controller in a communication way. The suspended type X-ray shooting system has the benefits that the X rays emitted by the bulb tube are perpendicular to the surface of the detector within a range of error plus/minus 1 degree, and an initial value is only required to be set once, the accumulated error can not be caused during the use process of the following equipment, error of position induction is caused due to loose gears, and maintainers are not required to conduct follow-up maintenance.
Description
Technical field
The present invention relates to suspension X ray camera chain, relate to detector and bulb anglec of rotation placement technology particularly.
Background technology
The X ray camera chain structurally has various ways, common at home have a UC arm configuration, U arm configuration and suspension structure, what the present invention relates to is suspension structure camera chain, its structure chart is referring to accompanying drawing 1 and accompanying drawing 2, Fig. 1 is a front view, Fig. 2 is a vertical view, suspension X ray camera chain mainly comprises installs crossbeam 1, photography bed 2, detector 3, column 4, moving guide rail 5, suspension bracket main body 6, retracting cylinder 7, bulb 8 and fixed guide 9, wherein, column 4 is fixed on the floor of machine room, detector 3 is installed on it, detector 3 can be around trunnion axis 31 rotations, also can do the oscilaltion campaign along column 4, photography bed 2 can move arbitrarily and the lockable position.Fixed guide 9 is fixed on to be installed on the crossbeam 1, and mobile moving guide rail 5 is installed on the fixed guide 9, and it can move along fixed guide 9 left and right directions.Suspension bracket main body 6 is installed on the moving guide rail 5, rectilinear motion before and after can doing along moving track 5; But retracting cylinder 7 is fixed on the suspension bracket main body 6 in the vertical direction and makes stretching motion.
The whole system operation principle is: patient lies on the photography bed 2, adjust the relative position between bulb 8 and the detector 3, make patient's lesions position be in bulb 8 focuses and detector 3 is accepted on the vertical line at face center, the x-ray that penetrates from bulb passes patient's lesions position and beats on the dash receiver of detector 3 after regulating the light open country like this, after digital processing, go up the image that generates lesions position at work station (computer), thereby the doctor can provide a diagnostic result.
The prior art shortcoming is: the X ray that bulb sends in the X ray suspension camera chain can not the vertical incidence detector surface, cause the X ray scattering inhomogeneous, and finally cause image blur, and difficulty is done the later image geometric correction.
Be to guarantee that X ray that bulb sends can the vertical incidence detector, existing bulb position feedback has two kinds of methods, and first kind is by on the bulb drive motors encoder being set, and by the position of encoder feedback bulb, its shortcoming is cumulative error is arranged and to cost an arm and a leg; Second kind is by the potentiometer dividing potential drop is set on the bulb drive motors, potentiometric magnitude of voltage calculates the motor physical location by sampling, the shortcoming of this scheme is to calculate gear transmission complexity between motor and potentiometer, limited by installing space, and be difficult to make full use of the potentiometer range, be subjected to the gear clearance error effect bigger simultaneously, require also higher A/D conversion accuracy.More than two kinds of schemes, the loosening or engagement of gear after life-time service, all can occur and tightly not cause position feedback to break down, increased cost of equipment maintenance.
Summary of the invention
The problem to be solved in the present invention is to guarantee that bulb keeps vertical all the time with detector surface in the scope of error+/-0.2 degree.
The present invention realizes that the technical scheme that goal of the invention adopts is, a kind of suspension X ray camera chain, comprise system master system device, detector and bulb, described detector is provided with first gyro sensor, be provided with second gyro sensor on the described bulb, described first gyro sensor and second gyro sensor all communicate to connect with master controller.
Preferably, described first gyro sensor is arranged on the marginal position of described detector.
Preferably, described second gyro sensor is arranged in the ox head display screen of described bulb.
Preferably, described first gyro sensor and described second gyro sensor communicate to connect by SPI interface or IIC interface and described master controller.
The invention has the beneficial effects as follows, can guarantee that the X ray that bulb sends keeps vertical all the time with detector surface in the scope of error+/-1 degree, and initial value only need be set one time, can not produce cumulative error in the follow-up equipment use, can not cause location sensitive to produce error, not need attendant's tracking and maintenance because of gear is loosening.
Description of drawings
Fig. 1, the structural front view of suspension X ray camera chain.
Fig. 2, the structure vertical view of suspension X ray camera chain.
Fig. 3, the partial structurtes figure of bulb of the present invention and detector.
Among the figure, 1 installs crossbeam, 2 photography beds, 3 detectors, 4 columns, 5 moving guide rails, 6 suspension bracket main bodys, 7 retracting cylinders, 8 bulbs, 9 fixed guides, 31 first gyro sensors, 81 second gyro sensors.
The specific embodiment
The structure of suspension X ray camera chain can be with reference to the accompanying drawings 1 and accompanying drawing 2, the existing introduction in its operation principle background technology, be not repeated herein, the present invention guarantees that the X ray that bulb 8 sends keeps vertical all the time with detector 3 surfaces in the scope of error+/-0.2 degree, a kind of suspension X ray camera chain is provided, the partial structurtes figure of bulb 8 and detector 3 is referring to accompanying drawing 3, comprise system master system device (not shown), detector 3 and bulb 8, detector 3 is provided with first gyro sensor 31, be provided with second gyro sensor 81 on the described bulb, first gyro sensor 31 and second gyro sensor 81 all communicate to connect by SPI interface or IIC interface and master controller, first gyro sensor 31 is arranged on the marginal position of detector 3, the second gyroscope sensing, 81 are arranged in the ox head display screen of bulb 8.
Among the present invention, detector 3 uses gyroscope as position sensor with bulb 8 rotations, can directly obtain detector 3 and bulb 8 current angles respectively with respect to gravity direction, between gyro sensor and the master controller, can use SPI or IIC interface communication to connect, when needs are obtained current location, master controller can read the gyro sensor currency, when being about to arrive predeterminated position, master controller sends control signal slows down motor, and gradable deceleration, gradually by at a high speed to the low speed transition, mechanical location approaches to predeterminated position gradually.Thereby realize position adjustment easily, guarantee that the X ray that bulb 8 sends can keep vertical all the time with detector 3 surfaces in the scope of error+/-0.2 degree bulb 8 and detector 3.
It should be noted that at last: above embodiment only in order to the explanation the present invention and and unrestricted technical scheme described in the invention; Therefore, it will be understood by those of skill in the art that still and can make amendment or be equal to replacement the present invention although this description has been described in detail the present invention with reference to each above-mentioned embodiment; And all do not break away from the technical scheme and the improvement thereof of the spirit and scope of the present invention, and it all should be encompassed in the claim scope of the present invention.
