Embodiment one：
Fig. 1 shows a this specific embodiment for medical imaging device positioner of the application, its traditional Chinese medicine
Image documentation equipment can be magnetic resonance equipment or CT equipment etc., it include equipment body 1 with lying bed receiving hole and
For the moveable lying bed being moved to person under inspection in the lying bed receiving hole of equipment body 1.In the present embodiment, Fig. 1 medical science
Image documentation equipment is MR imaging apparatus, and its equipment body 1 includes being used for the magnet for producing main field, the center of foregoing main field
Generally with the center superposition of foregoing lying bed receiving hole.
The positioner includes computing unit and the location marker 3 and location indentifier 4 of mutual cooperation, wherein, position
Putting the position of concentrator marker 3 can arbitrarily be moved in space, and the position of location indentifier 4 is relatively fixed with equipment body 1.Know position
Other device 4 is connected with location marker 3, for obtaining the current positional information of location marker 3.Computing unit is used to calculate position
Put the distance between location marker position and person under inspection position target location to be examined of the acquisition of identifier 4.
During practical application, after person under inspection is arranged to lying bed 2, location marker 3 is moved to person under inspection position to be examined (ratio
Such as neck or waist).The location indentifier 4 is obtained the position of current location identity device 3 because location indentifier 4 with
The relative position of equipment body 1 be it is changeless, what the target location at person under inspection position to be examined also was to determine --- be usually
The center (and for magnetic resonance equipment, typically the magnetic field center of main field) of lying bed receiving hole, location indentifier 4 with by
The relative position of inspection person position target location to be examined is fixed.Predefine good person under inspection position target location to be examined (generally
For the center of lying bed receiving hole) (coordinate is given value, and set for same set of medical image for coordinate in space coordinates
For standby, the coordinate is fixed value), and location indentifier 4 gets the coordinate of the current location of location marker 3, then calculate
Unit can just calculate the distance between location marker current location and person under inspection position target location to be examined, and position is marked
Know device 3 current location be in person under inspection position to be examined current location it is neighbouring (essentially coinciding), then afore-mentioned distance is approximately
(error is smaller and is receiving model for the distance between person under inspection position current location to be examined and person under inspection position target location to be examined
In enclosing, this error amount depends on operator to the deviation size between the position location of location marker 3 and person under inspection position to be examined).
So, it is determined that behind the distance between person under inspection position current location to be examined and person under inspection position target location to be examined, the image
Equipment can distance value control lying bed 2 moves corresponding distance and person under inspection position to be examined is moved to target location.
If in view of location marker 3 and location indentifier 4 using the line connection for having cable, then in movement
During location marker 3, very long circuit will be dragged, it is both dangerous, it is also inconvenient, while cable is also existed after long-term drag
Risk of breakage, security are poor.For this problem, the present embodiment is by the connected mode of location indentifier 4 and location marker 3
Be arranged to wireless connection, the mode of the wireless connection can be radio frequency connection, WIFI connections, light path connection, photoelectricity connection or
Bluetooth connection.
Because location marker 3 can move freely, its can not possibly all the time all in person under inspection position to be examined, if
Location indentifier 4 is in real time all in the position of test position concentrator marker 3, then will necessarily cause position initial bit to be examined to person under inspection
The false judgment put, cause disturbance locating, while can also consume substantial amounts of energy (electric energy).For this problem, embodiment exists
The position identification trigger switch that trigger position identifier 4 is opened/closed is provided with location marker 3.Only when operator touches
When the dynamic position identifies trigger switch and makes the unlatching of trigger position identifier 4, trigger position identifier 4 just can be with station location marker
Position identification connection is established between device 3, and (trigger position identifier 4 makes position by controlling being turned on and off for location indentifier 4
The connection put between identifier 4 and location marker 3 is switched on or switched off), at this time location indentifier 4 just understands test position concentrator marker
3 current location.And if position is foregoing when putting identification trigger switch and being closed trigger position identifier 4, position is known
Other device 4 and location marker 3 will not establish position identification contact, location indentifier 4 will not test position concentrator marker 3 present bit
Put.
Obviously, identification trigger switch in above-mentioned position can also be arranged for trigger position concentrator marker 3 (and non-location identifies
Device) it is turned on and off, it is equally reached the effect above.Closing to location marker 3, refer to allow location marker 3 to refuse
The relevant action of receiving position identifier 4, such as the photosignal that rejection location indentifier 4 is sent.
It is highly preferred that above-mentioned position identification trigger switch is arranged to reset switch by us, the reset switch is in natural shape
It is closed location indentifier 4 (or location marker 3) under state.When touching (such as pressing) reset switch, position
Put the current location of the test position concentrator marker 3 immediately of identifier 4, unclamp reset switch then homing and in the raw,
The position of the no longer test position concentrator marker 3 of location indentifier 4, the connection between the two are in " resting state " and (alternatively referred to as disconnected
State).Or after shake-up reset switch makes location indentifier 4 detect the current location of location marker 3, without manual
Reset switch is unclamped, location indentifier 4 voluntarily stops the detection to the position of location marker 3, that is to say, that position under normal conditions
Connection between identifier 4 and location marker 3 (is disconnected) in a dormant state, and the action of position identification trigger switch is played instantaneously
Wake up the effect of dormancy --- often touch a position identification trigger switch and only carry out a position detection.
Position identification trigger switch is arranged to reset switch and also has an extraordinary advantage：During image check, when by
After inspection person is placed in lying bed 2, location marker 3 need to only be put in person under inspection's near sites to be examined and press thereon by medical worker
Position identifies trigger switch, and location indentifier 4 just can know current location (the i.e. depressed position identification of location marker 3 rapidly
The location of location marker 3 during trigger switch).And hereafter, the connection between location indentifier 4 and location marker 3 is at once
Recover to " resting state ", location indentifier 4 will not test position concentrator marker 3 position, at this moment medical worker's can is random
The position of shift position concentrator marker 3, it is very convenient without it to be placed on to person under inspection's near sites to be examined all the time.
In order to further improve operation ease of the medical worker to the positioner, the present embodiment is in location marker 3
On be additionally provided with for the location marker 3 to be worn on to the wearing of medical imaging device operator (medical worker) hand
Body --- such as bandage or refer to is buckled.During practical application, location marker 3 is fixed at the palm of medical worker using bandage
Or at arm, location marker 3 can also be fixed on the finger of medical worker (such as same ring) using button is referred to.
In addition, we can also connect the lying bed drive device (generally motor) of lying bed 2 with above-mentioned computing unit circuit
Connect, after computing unit calculates afore-mentioned distance, the automatic moving respective distance of lying bed 2, realize person under inspection's spots localization to be examined and
Lying bed 2 move operating in a key, at this time position identification trigger switch also taken on to lying bed 2 move control.Certainly, I
Can also be separately provided one (the lying bed moving switch can be set with the lying bed moving switch that separates of position identification trigger switch
Put on location marker, can also be arranged on image documentation equipment.), the movement of lying bed 2 is controlled by lying bed moving switch.
In Fig. 1, it is z-axis, with perpendicular to paper to establish with the left and right directions (the head pin direction of person under inspection) parallel to paper
The inward-outward direction (left and right directions of person under inspection) in face is x-axis, with the above-below direction (fore-and-aft direction of person under inspection) parallel to paper
For the three-dimensional system of coordinate of y-axis.Above-mentioned location indentifier 4 can only catch position concentrator marker 3 z coordinate, can also only capture
The z coordinate and y-coordinate or z coordinate and x coordinate of location marker 3, x coordinate, the y of acceptable whole catch position concentrator markers 3
Coordinate and z coordinate.Preferably, the z coordinate and y-coordinate of catch position concentrator marker 3, or x coordinate, y-coordinate and z coordinate, equipment
Two are calculated according to the z coordinate of the current z coordinate of location marker 3 and target location (the generally center of lying bed receiving hole)
Person z directions distance, then control bit lying bed 2 be moved along the z-axis, and cause person under inspection's preliminary examination position and target location with
Identical z coordinate, the contraposition at person under inspection's preliminary examination position is completed, because existing medical imaging device is after person under inspection lies
The z of lying bed can only be realized mostly can not carry out the movement in x and y directions to movement.It can be seen that now person under inspection's preliminary examination position is not
Have and be completely superposed with target location, and be only that there is identical z coordinate, the skew that x directions and y directions therebetween be present
Amount, and the two offsets can be according to the x coordinate of location marker 3 before and y-coordinate (namely person under inspection's preliminary examination portion before contraposition
The x coordinate and y-coordinate of position) calculate (if using target location as the origin of coordinates, then the two offsets are exactly position mark
Know the x and y coordinates of device 3 in itself), then equipment can more accurately sets the central point of positioning picture according to the two offsets
And the central point in active shimming area, without carrying out the scanning of multiple bearing picture or the configuration of artificial coordinate offset amount.
Further, it is contemplated that the home position of location marker 3 generally will not be complete with person under inspection position center to be examined
Overlap, the two has certain deviation, and we can reduce this deviation using this localization method：In positioning action,
Medical worker, which tries one's best, is placed on location marker 3 surface at person under inspection position to be examined, and is preferably close to position to be examined.
The height (y-coordinate) of lying bed 2 is given value, and the half of the y-coordinate of location marker 3 and the y-coordinate sum of lying bed 2 is with regard to non-
Very close to the y-coordinate of person under inspection position center to be examined (a points position in Fig. 1), (person under inspection is to be examined, and position center is substantially at Fig. 1
The point midway that middle location marker 3 and lying bed 2 are lain between face)., can be direct when imaging inspection sets the central point of positioning picture
The y-coordinate of the central point of the positioning picture of medical imaging device is set as aforementioned location concentrator marker y-coordinate and lying bed y-coordinate sum
Half.The x coordinate for positioning inconocenter point is set as to the x coordinate of location marker, the z coordinate of inconocenter point will be positioned
It is set as the z coordinate of person under inspection position target location to be examined.
Embodiment two：
Fig. 2 shows this another specific embodiment for medical imaging device positioner of the application, this reality
Apply that structure and above-described embodiment one of this positioner of example are closely similar, and the main distinction is the present embodiment by location marker
3 are relatively fixed with the position of equipment body 1, and the position of location indentifier 4 can move freely.Location indentifier 4 and station location marker
Device 3 is connected, and so as to obtain the relative position information of location indentifier 4 and location marker 3, and then computing unit can basis
Relative position between location indentifier 4 and location marker 3 calculates the position of location indentifier 4 and person under inspection's position target to be examined
The distance between position.
Specifically, because the position of location marker 3 be it is fixed and known to, the position captured by location indentifier 4 is marked
It is position of the location marker 3 relative to identifier 4 to know the position of device 3, has known the location marker 3 and the He of location indentifier 4
Between relative position information, then be also just capable of the positional information (coordinate) of release location identifier 4, then further according to position know
The positional information calculation of other device 4 goes out it the distance between with person under inspection position target location to be examined (this is Given information).
The localization method of this medical imaging device of the present embodiment and localization method in above-described embodiment one are basically identical,
This is not repeated.
Above content is to combine the further description that specific embodiment is made to the application, it is impossible to assert this Shen
Specific implementation please is confined to these explanations.For the application person of an ordinary skill in the technical field, do not taking off
On the premise of conceiving from the application, some simple deduction or replace can also be made.
