The detailed description of most preferred embodiment
Referring now to accompanying drawing, be Fig. 1 and Fig. 2 specifically, the MR imaging apparatus that one embodiment of the present of invention are related schematically has been described.
MR imaging apparatus comprises a support component 1, and it exists with the form of vertical wall.Magnet structure 2 is installed on the described support component 1 in the mode of dangling.Described magnet structure 2 comprises two relative magnetic poles 102,202, these two magnetic poles are vertical orientated with respect to supporting walls 1, and rely on a post or wall 302 to couple together, be spaced from each other, and described post or wall are parallel to supporting walls 1 and extend, and by being installed on this supporting walls perpendicular to supporting walls 1 and perpendicular to a bar 3 of the horizontal connecting wall 302 of magnet structure 2.Can rotate in the cavity of described bar 3 in supporting walls, its axle also is parallel to magnetic pole 102,202 and perpendicular to the magnetic field that produces between the magnetic pole.The axle of described bar 3 is consistent with the symcenter of wall 302 in the described magnet structure, although this be not one for the necessary characteristics of the function that guarantees this MR imaging apparatus.
A coaxial front end on supporting walls 1 has the 101 and driving pinions 4 in crown top to cooperatively interact, and this pinion wheel is subjected to the driving of motor 5 by kinematic train 6.Therefore, described motor 5 can make magnet structure 2 rotate with respect to supporting walls 1 around the axle of described bar 3.Be installed on the supporting walls 1 although the front end among the figure has the coaxial hat top 101 of tooth to be shown as, the crown overhead will be arranged on the wall 302 of magnet structure, also can realize same effect and motor 5, kinematic train 6 and pinion wheel 4 placed on the supporting walls.This solution is avoided element is placed on the described wall 302, disturbs otherwise can produce the loop of the magnetic flux in the described wall 302.
By the combination of guide rail and saddle, described estrade 7 is supported and vertically can slide at it, also provides drive unit to make described estrade 7 to move with respect to magnet structure 2.
In the present embodiment, two vertical saddles 107 are provided below estrade 7, and are fixed on the estrade.Saddle 107 extends both sides longitudinally along estrade 7, is connected with guide rail 8,8 ' slip, and guide rail is positioned at the lateral end place of the lower magnetic pole 102 of magnet structure.
The combination that is fixed on the pinion wheel of longitudinal rack on the estrade 7 and motor driven has guaranteed that estrade moves along its longitudinal axis is two-way.
As illustrated that described tooth bar also can be made of one or two saddle 107, there is toothed longitudinal region on its surface, can be in one or two guide rail 8,8 ' the corresponding pinion wheel 4 of recess be connected.Described pinion wheel is that pinion wheel 4 is driven by a bar 104 by motor 9.See Fig. 2 and 11.
As shown in figure 11, saddle 107 and guide rail 8,8 ' the cross section formed the recessed structure of mutual side, to avoid skidding off guide rail when magnet structure and sick platform 7 saddle 107 when sick platform horizontal level forwards the upright position to.
Can select a lot of different design of slide block and guide rail.Be presented at a simple solution among Figure 11 and be included in the continuous tooth 207 in a side on each saddle 107, it is connected mutually with side succeeding vat 108 in the corresponding sidewall.
In addition, the releasable locking device of a unshowned estrade 7 with respect to magnet structure 2 arranged.This locking device may reside in the combination of rack-and-pinion mechanism, if motor has disconnected power supply, this mechanism perhaps can be irreversible.Selection in addition is, can use mechanical lock device, the lock tooth of for example releasable and tooth bar engagement, and by manual, electronic or other the driving of actuator, this device can be driven on the passive position of the active position of a joint and disengaging in turn.
According to another feature, estrade 7 also can slide on the direction perpendicular to its longitudinal axis, promptly slides on the direction perpendicular to the wall in the magnet structure 2 302.This can be similar to reference to the described way of vertically moving of estrade 7 by one and realize.
According to illustrated example, at the guide rail on each end of magnetic pole 102 8,8 ' be positioned on the horizontal saddle 10, this horizontal saddle is connected mutually with a cross slide way 11.The xsect of cross slide way and saddle can have the recessed structure of intermeshing side, as the description about vertical saddle and guide rail shown in Figure 11.Moving transversely can be driven by the combination of motor 9 ' by rack-and-pinion, as the detailed description about longitudinal rail and saddle.
For laterally moving of sick platform 7, releasable locking device also is provided, the activation of this locking device and deactivation are as the description that vertically moves employed releasable locking device about sick platform 7.
Because the top structure of announcing, when described magnet structure and estrade turned to the horizontal level of magnetic pole 102,202 and estrade 7, described MR imaging apparatus of the present invention can be positioned at the patient on the estrade 7.
In order to allow patient lie on the estrade 7, estrade 7 perhaps needs to be pulled to its maximum length travel place, as shown in Figure 3.After patient correctly lay on the estrade, this estrade can vertically move with respect to magnet structure 2 at it, if perhaps provide condition also can laterally move at it.Fig. 4 has illustrated the different relative position of estrade 7 with respect to magnet structure 2 to Fig. 6.
Fig. 3 has also clearly illustrated to Fig. 6, not only allow backbone is carried out useful imaging according to MR imaging apparatus of the present invention, and, because estrade 7 can move continuously at vertical and horizontal, patient's different anatomic region can be placed between two magnetic poles 102,202 in the formed inspection space at every turn, thereby carry out different inspections.
For the estrade 7 that reduces to dangle at the load (Fig. 3 and Fig. 6) of its extreme position to guide rail and saddle, can be at one or two terminal leg 15 that a pair of belt wheel is installed of estrade, as shown in Figure 1.So just allow estrade from magnet structure, to extract its almost whole length out, suppose that the end that the belt wheel supporting leg is not installed can engage with magnet structure on whole terminal length.
In case patient has lain on the estrade 7, magnet structure 2 rotates an angle of 90 degrees together with regard to energy and estrade 7.On this position, estrade is vertical, and patient is in the stand up position.In order to allow patient to reach this stand up position,, provide a footstool relevant 12 with pin at the end of estrade.This footstool can be fixed, perhaps it can be made of a plate, after with patient location, this plate is installed in the appropriate position of estrade, perhaps this footstool can be made of the extension of estrade 7, this extension is installed on the estrade 7 with hinge, make can be alternately at hanging position and be parallel on the position of remainder of estrade 7 and be pulled up and prop up.
See that from Fig. 7 and Fig. 8 are clear magnet structure and estrade can rotate the angles less than 90 degree, therefore can regulate patient's oneself the epispinal load of patient that weight is added in.
In case finished imaging, magnet structure 2 and estrade 7 can be rotated on the position that estrade 7 is level once more.Estrade is moved to its extreme position then, and patient just can leave this and install.
According to further improvement shown in Figure 10, can provide an independently supporting construction 20 for estrade 7.This independently supporting construction constitute by the shelf of leg upper belt-wheel.Described supporting construction 20 has guide rail 8 at its top ", vertical saddle 107 pairing guide rails 8,8 of this guide rail and estrade 7 ' all identical on position and xsect.Therefore, by being the guide rail 8 on the independent support structure 20 that estrade 7 prepares " with guide rail 8,8 on the magnetic pole 102 ' align, estrade 7 can by vertically move from described supporting construction 20 transfer to guide rail 8,8 on the magnetic pole 102 ' on, vice versa.Therefore, patient can do the preparation of inspection on the estrade outside the magnet structure, and simultaneously another patient is admitted in the device and checks.
Because estrade 7 can be sent into the magnet structure and extracts magnet structure out from a relative end from an end, by at least two support shelves 20 are provided at least two estrades 7, one on each estrade just may be controlled transporting of examine patient.
In this case, the estrade that is loaded with the patient who just finishes inspection is from magnet structure, such as the left hand end of the structure 2 from Figure 10 is drawn out of, and the estrade 7 that is loaded with next patient simultaneously is admitted to the magnet structure from the right hand end of magnet structure 2.
This solution also allows to allow patient prepare for checking on the estrade outside the magnetic imaging device, and like this, a patient is when preparing for inspection, and another patient checks in device.By at an end of magnet structure bed or estrade and magnet structure being broken away from, and at its relative end next one bed or estrade are engaged with magnet structure, described device becomes more reasonable aspect the transporting of patient.
Provide the guide rail of orientation perpendicular to estrade 7 self longitudinal axis by the supporting construction for estrade 7, estrade 7 is to the insertion of magnet structure 2 and also can transversely carrying out at estrade 7 from the extraction of magnet structure 2.
According to another feature as shown in Figure 9, can provide a seat 21.This seat 21 can be located to be directly installed on the estrade 7 at various height, and a support bar 22 perhaps can be provided, and this support bar is installed in estrade 7 from or be installed on the magnet structure on one's body, is parallel to estrade 7.Described bar 22 is carrying a seat that dangles, and this seat is installed on the described bar by a saddle that engages with described bar, provides releasable locking device so that seat 21 is locked on the height of hope.
