Detailed description of the invention
The present invention is further detailed in conjunction with the accompanying drawings below:
Set forth a lot of detail in the following description so that fully understand the present invention.But the present invention can be much different from alternate manner described here to implement, those skilled in the art can when without prejudice to doing similar popularization when intension of the present invention, therefore the present invention is by the restriction of following public concrete enforcement.
Secondly, the present invention utilizes schematic diagram to be described in detail, when describing the embodiment of the present invention in detail; for ease of explanation; represent that the profile of device architecture can be disobeyed general ratio and be made partial enlargement, and described schematic diagram is example, it should not limit the scope of protection of the invention at this.In addition, the three-dimensional space of length, width and the degree of depth should be comprised in actual fabrication.
Fig. 4 shows the schematic diagram of thread spool positioner of the present invention.
Refer to shown in Fig. 4, Fig. 5, the invention provides a kind of thread spool positioner, comprise coil device 1, also comprise:
Label 3, is arranged on determinand 4;
Checkout gear 5, is positioned at described coil device 1, for detecting described label 3 and producing detection signal;
Control unit 6, is connected with described checkout gear 5, to receive detection signal that described checkout gear 5 produces and to judge determinand 4 position of described label 3 correspondence according to described detection signal.
Described thread spool positioner also comprises a display device 7, connects described control unit 6 to show the position of described label 3.
Described checkout gear 5 comprises at least one group of transmitting terminal and receiving terminal, described transmitting terminal is used for transmitting, the reflected signal of described receiving terminal for transmitting described in receiving, detection signal is produced according to described reflected signal, described checkout gear 5 can be popped one's head in for Emission and receiving of infrared, and described checkout gear 5 can also be that Laser emission and laser pick-off are popped one's head in;
Described control unit 6 determines whether corresponding with label 3 and label 3 is corresponding according to the position judgment of described receiving terminal determinand 4 position of received detection signal.
With a specific embodiment, the present invention is described below, in the present embodiment, described determinand 4 is for hands, described checkout gear 5 is for Emission and receiving of infrared probe, described display device 7 is for magnet panel, easily be fixed on the article at wrist place as label 3 with bracelet or other, described infrared emission probe is used for transmitting to described label 3, and described infrared receiver probe is for receiving the transmitting terminal signal reflected by described label 3.Different to the reflectance of different article according to Infrared, for the people that the colour of skin such as yellow, white people is more shallow, skin can reflective infrared light largely, now use black bracelet or the very poor article of other reflexive as label, the ethnic group that the colours of skin such as corresponding black people are darker, just with white bracelet or the very strong article of other reflexive as label 3.Due to skin and bracelet larger for the reflection coefficient difference of Infrared, infrared receiver probe receives the infrared signal be reflected back through determinand, due to the existence of label 3 on determinand 4, the voltage of label 3 infrared receiver probe when Emission and receiving of infrared is popped one's head in can change, by comparing with the voltage preset, Emission and receiving of infrared probe can be identified and detect label.Because coil device 1 is popped one's head in built with several Emission and receiving of infrared, like this, the launching and receiving probe of diverse location can obtain a level change by detecting wrist place label 3.As Fig. 3, control unit 6 receives the level change of each infrared receiver probe, control unit 6, according to the level change obtained from different infrared receiver probe, judges the position residing for hands, and on magnet panel, shows the geometric center position relative to wrist portion coil.
When wrist portion is positioned over second coil unit 22 time, although be also in the position that the second coil unit 22 is corresponding, but not in optimal position, as shown in Figure 6, because now hands has put into coil device 1, label 3 is received by the corresponding infrared receiver probe of tertiary coil unit 23 or the first coil 21 place, detected by the infrared receiver probe of front and back label 3 time before and after, control unit 6 can judge the direction of motion of selling and speed, indicate hand present position deviation, on magnet panel, display is sold and how to be placed to make wrist portion aim at the center of the second coil unit 22, ensure to reach best scanning effect.
As shown in Figure 7, Figure 8, the solid black lines Blocked portion that magnet panel shows represents and proportionally carrys out convergent-divergent coil dimension, the dashed rectangle of black then illustrates the position of current hands placement relative to coil unit, situation shown in Fig. 7 represents that hands is placed advanced, hands moves by system prompt client need backward, until dotted line and bold portion are on same vertical plane, do not need by magnetic resonance equipment prescan hand position, avoid multiple scanning to adjust hand position accurately to locate simultaneously, as shown in Figure 8, then show that the position of hand placement is desirable.Adopt the bracelet in wrist as the some Emission and receiving of infrared probes in label 3 and coil device in the present embodiment, utilize the different reflectivity of label 3 and hand, the reflected signal putting into process infrared receiver probe reception label 3 at hand detects that level changes, the position that label 3 place place is corresponding with coil unit is judged again through control unit 6 process, and shown by display device 7, time undesirable, by prompt system prompting patient, how this places hand accurately to locate the position of hand to system, or doctor moves by display device prompting patient the position that hand accurately locates hand, the correct position when determinand of the Image Adjusting label labelling shown by display device does magnetic resonance detection to the coil unit of magnetic resonance device, thus avoid the prescan work for determining hand position and multiple scanning operation, improve coil utilization rate.
It should be noted that, in the present embodiment, described label 3 on the Detection results of magnetic field and determinand 4 all without impact, described checkout gear 5 on the main field of magnetic resonance device and the magnetic field of coil unit without impact.Above-described embodiment orientates example as with hand, the present invention is not limited thereto, and can also be the location at other position, and the present invention can also have other embodiment, such as:
Described label can be fluorescent material, and checkout gear 5 is the device receiving light, is determined the position of label 3, then adjust accurately to locate determinand by control unit 6 and display device 7 by the optical signal receiving label 3.
Described display device can be the original display device of magnetic resonance device, and described control unit can be the modified model control unit of the processing capacity increasing the sensor signal to positioner of the present invention on the basis of the original control unit of magnetic resonance device.The present invention adopts the position of label labelling determinand, and the position of label is determined by checkout gear, the correct position when determinand adjusting label labelling again does magnetic resonance detection to the coil unit of magnetic resonance device, thus avoid the prescan work for determining determinand position and multiple scanning operation, improve coil utilization rate.
