Specific embodiment
The specific embodiment of the present invention is described further below in conjunction with the accompanying drawings.It should be noted that for
The explanation of these embodiments is used to help understand the present invention, but do not form limitation of the invention.It is in addition, disclosed below
The each embodiment of the present invention in involved technical characteristic can be combined with each other as long as they do not conflict with each other.
As shown in Figure 1, the medical imaging control system of the present invention includes computer 1, arena 8, detector 9 etc..Arena 8 is
Equipment in system for being generated and transmitted by X ray.Detector 9 is the equipment that can be received X ray and generate image.In this reality
It applies in example, image acquisition units 2 are arranged on arena 8, and the week of arena 8 is acquired from the position of arena 8 to its periphery
Edge image information.Model data unit 3 carries out the foundation of coordinate system based on side images information.Wherein, coordinate system is with the ball
8 position of shop is origin, and the direction of the ray emission of the arena 8 is X-axis.Thus, it is possible to coordinate system is based on from these weeks
Elevation information and azimuth information of the detector 9 relative to the arena 8 are obtained in edge image information.Model data unit 3 can also
The enough air line distance obtained on the basis of coordinate system between the focus of arena 8 and detector 9.Arena 8 and detector 9 is direct
Line may have certain angle between the line and X-axis between them.Model data unit 3 is obtained between line and X-axis
Angle information.
Then, according to angle information, detector control unit 5 can control detector 9 to move, so that the institute after mobile
The line stated between detector 9 and the arena 8 is overlapped with the X-axis.That is, the detector 9 after mobile will be in arena 8
Ray emission positive direction on.Medical imaging control system further includes automatic focusing unit 4.Automatic focusing unit 4 can be micro-
Arena 8 is adjusted, the mode of fine tuning is exactly that arena 8 is controlled to rotate upwardly and downwardly, so that the focus of the arena 8 and the detector 9
Center is aligned.
Preferably, can be human body or animal suitable for the object to be detected of present system.The present invention is also applicable in
In the filming image of the animal of big build.The invention also includes mobile stations 7 and mobile unit 6.The mobile station 7 is treated for placing
Detectable substance, the object to be detected to be driven to move.And mobile unit 6 is used to determine the position to be detected of the object to be detected, example
As having the model of the object to be detected in computer 1, user of service, which is previously entered, needs which region for detecting object to be detected.So
Afterwards, the region detected according to the needs of input, mobile unit 6 are able to detect that the to be detected of the object to be detected in mobile station 7
Position 10, and demarcate the region (object to be detected is needed to keep opposing stationary at this time).Then, computer 1, which is calculated, marks this
Fixed position to be detected 10 is moved to required movement between the focus of the arena 8 and the center of the detector 9
Amount.Amount of movement includes the distance of the distance and vertical shift moved horizontally.As shown in Fig. 2, mobile unit 6 has obtained amount of movement
Afterwards, the mobile station 7 is controlled to move, so that the position 10 to be detected is moved to the coke of the arena 8 by the mobile station 7
Between center described in point and the detector 9.
As shown in figure 3, and when the position to be detected area be more than the detector imaging area when, it is Polaroid
Photographing request can not be met.Therefore, mobile unit 6 and computer 1 according to the imaging area by the face at the position to be detected
Product is divided into multiple regions block in order.For example, according to clock-wise order either according to sequence counter-clockwise or according to laterally suitable
Sequence or according to vertical sequence.By position to be detected according to being laterally sequentially divided into position 1 to be detected, to be detected in Fig. 3
Position 2 12, position to be detected 3 13.Region unit is respectively moved to the arena 8 by the mobile station 7 according to the sequence
Between the center of focus and the detector 9, so that detector 9 respectively obtains multiple images in sequence.Computer 1
Obtained multiple images are synthesized in sequence.
Preferably, the communication in system of the invention between each unit and control be all by the computer 1 at center with
And the multiple conducting wires realization being connected with computer 1.
Embodiments of the present invention are explained in detail above in association with attached drawing, but the present invention is not limited to described implementations
Mode.For a person skilled in the art, in the case where not departing from the principle of the invention and spirit, to these embodiments
A variety of change, modification, replacement and modification are carried out, are still fallen in protection scope of the present invention.
