A kind of incidence MR imaging apparatus and system thereof
The invention belongs to medical imaging technical field, particularly relate to the special MR imaging apparatus of a kind of incidence and system thereof.
Magnetic resonance (MR) imaging the health of person under inspection or a part of health is placed in main field carry out the technology that scanning shoot obtains medical imaging.Show that MR clinical examination about 50% comes from incidence inspection according to hospital's Using statistics; for existing MR equipment; not only bulky; expensive; and narrow owing to checking space, when carrying out magnetic resonance examination, for the patient of frightened enclosed space; they usually can feel to check and bring unhappy even cannot carry out magnetic resonant imaging examination.
Therefore the magnet and the magnetic resonance device that design the special MR of a kind of incidence coordinate whole body type MR device to use, and can solve above Problems existing.
Summary of the invention
The object of this invention is to provide a kind of MR imaging apparatus magnet magnetic resonance device and system thereof, not only structure is simple, volume simplifies, and be beneficial to patient and use.
In order to solve the problems of the technologies described above, the invention provides following technical scheme: a kind of incidence MR imaging apparatus, comprises magnet, patient support device, scanning control system, described magnet outer ring is integrated with radio-frequency field transmitting/receiving coil layer; Described radio-frequency field transmitting/receiving coil outer ring sets gradually gradient field coil field and magnet superconducting line ring layer.
Further, described magnet one end is provided with lip sample epitaxy part.
Further, described magnet is connected with a liftable supporting mechanism, and described supporting mechanism is fixedly connected with and ground or body of wall
Further, described patient support device is syllogic chaise longue, is placed in the below of described magnet.
In order to solve the problems of the technologies described above, the present invention also provides another kind of technical scheme: described MR imaging apparatus is connected with a set of time-sharing control system, time-sharing control system and then connect the operation corresponding to described MR imaging apparatus and display terminal, realizes carrying out Time-sharing control to multiple stage MR imaging apparatus.
Radio-frequency coil, gradient coil and magnet superconducting coil, owing to adopting the above technical scheme, are integrated in magnet part, greatly reduce the volume of magnet coil part by the present invention, then make magnet can realize lifting under the support of reduction parts; Patient is made to be in a kind of comfortable therapeutic state; And due to described magnetic resonance system can magnetic resonance device described in Time-sharing control multiple stage, greatly can save the purchase cost of hospital.

Detailed description of the invention
Below will be described in further detail MR imaging apparatus of the present invention and system thereof.
As depicted in figs. 1 and 2, a kind of incidence MR imaging apparatus, comprises magnet 31, patient support device 4 and scanning control system (not shown).Described magnet 31 is annular, and the internal orifice dimension of annulus is about 300mm, is applicable to the inspection of most human body incidence; Field intensity is suitably 1.5T or 3.0T superconducting magnet.The outer ring of magnet 31 is integrated with radio-frequency field transmitting/receiving coil layer 32; Described radio-frequency field transmitting/receiving coil outer ring 32 sets gradually gradient field coil field 33 and magnet superconducting line ring layer 34.As shown in Figure 3, described magnet 31 1 end is provided with lip sample epitaxy part 311, and described lip sample epitaxy part 311 structure and patient 1 shoulder are fitted, be convenient to patient 1 under sprawl shoulder near magnet 31.Described magnet 31 is connected with a liftable supporting mechanism 2, and described supporting mechanism 2 is connected with wall face supporting.Magnet by control lifting, translation and Arbitrary Rotation, can enter scanner inspection to facilitate adaptation patient incidence under the different gestures such as seat, semireclining position.Be patient support device 4 below described magnet 31, in the present embodiment, described patient support device 4 is syllogic chaise longue, the supporting head part section of described patient support device 4 is near magnet arrival end, described syllogic chaise longue also can coordinate the adjustment of degree of freedom such as rotating, folding according to the position of magnet 31, after patient takes a seat, head obliquely, by lifting magnet 31 and adjustment patient support device 4, patient's incidence is made conveniently to enter magnet internal check.
Certainly, above superconducting magnet also can replace to permanent-magnet type magnet.
Because radio-frequency field transmitting/receiving coil outer ring 32, gradient coil 33 and magnet superconducting coil 34 are integrated in magnet 31 part by the present invention, greatly reduce the volume of magnet 31 and coiler part, then magnet 31 is made can to realize the adjustment of position under the lifting of supporting mechanism 2, make patient 1 be convenient to comfortable acceptance scanning, especially relieve the misery of claustrophobia patient 1.
Consider the actual demand amount of the special MR system of incidence, probably occur that same hospital is equipped with the situation more than 1 title neck special machine.Due to software, applied system design specificity comparatively strong (only providing incidence to scan), can consider to adopt a set of electronics rack and computer for controlling to carry out the control of multiple stage scanning system, rebuild image after operating host and scanning and post processing can support multiple stage terminal access.As shown in Figure 4, the present embodiment also provides another kind of technical scheme: a kind of magnetic resonance system, comprise at least two magnetic resonance devices 1 as above, 2......n, magnetic resonance device described in multiple stage is connected with a set of time-sharing control system, time-sharing control system so that connect corresponding n platform operation and display terminal.When operator operates described terminal, when transmitting control command to time-sharing control system, the wherein described magnetic resonance device in time-sharing control system meeting gating magnetic resonance device 1,2......n, described magnetic resonance device starts to diagnose patient; The data that diagnosis obtains to described terminal, carry out image procossing by time-sharing control system reverse transfer.The above can realize, by magnetic resonance device described in a set of time-sharing control system Time-sharing control multiple stage, substantially increasing resource utilization, saves the purchase cost of hospital.
Obviously, those skilled in the art can carry out various change and modification to the present invention and not depart from the spirit and scope of the present invention.Like this, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these change and modification.
