A kind of incidence MR imaging apparatus and system thereof
This utility model belongs to the medical imaging technical field, relates in particular to a kind of incidence special-purpose MR imaging apparatus and system thereof.
Magnetic resonance (MR) imaging is to place main field to carry out the technology that scanning shoot is obtained medical imaging person under inspection's health or a part of health.Use statistics to show that MR clinical examination about 50% comes from the incidence inspection according to hospital, for existing MR equipment, not only bulky; Cost an arm and a leg; And because the inspection space is narrow, when carrying out magnetic resonance examination, for the patient of frightened enclosed space; They usually can feel to check bring unhappy, even can't carry out magnetic resonant imaging examination.
Therefore the magnet and the magnetic resonance device that design the special-purpose MR of a kind of incidence cooperate whole body type MR device to use, and can solve the problem of above existence.
The utility model content
The purpose of this utility model provides a kind of MR imaging apparatus with magnet magnetic resonance device and system thereof, and not only simple in structure, volume is simplified, and is beneficial to patient's use.
In order to solve the problems of the technologies described above, this utility model provides following technical scheme: a kind of incidence MR imaging apparatus comprises magnet, patient support device, scanning control system, said magnet outer ring is integrated radio-frequency field emission/receiving coil layer; Said radio-frequency field emission/receiving coil outer ring sets gradually gradient field coil field and magnet superconducting line ring layer.
Further, said magnet one end is provided with epitaxy part.
Further, said magnet is connected with a liftable supporting mechanism, and said supporting mechanism is fixedly connected with ground or body of wall.
Further, said patient support device is the syllogic chaise longue, places the below of said magnet.
In order to solve the problems of the technologies described above; This utility model also provides another kind of technical scheme: said MR imaging apparatus is connected with a cover time-sharing control system; Corresponding operation of time-sharing control system and then connection and said MR imaging apparatus and display terminal are realized many MR imaging apparatus are carried out timesharing control.
This utility model is integrated in magnet part owing to adopt the above technical scheme with radio-frequency coil, gradient coil and magnet superconducting coil, has dwindled the volume of magnet coil part greatly, but has made magnet can under the support of reduction parts, realize then; Make the patient be in a kind of comfortable therapeutic state; And, can save the purchase cost of hospital greatly because described magnetic resonance system can timesharing be controlled many described magnetic resonance devices.

The specific embodiment
Below will the MR imaging apparatus and the system thereof of this utility model be done further to describe in detail.
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).Said magnet 31 is an annular, and the internal orifice dimension of annulus is about 300mm, is fit to most human body incidence inspections; Field intensity is suitably 1.5T or 3.0T superconducting magnet.The outer ring of magnet 31 is integrated radio-frequency field emission/receiving coil layer 32; Said radio-frequency field emission/receiving coil outer ring 32 sets gradually gradient field coil field 33 and magnet superconducting line ring layer 34.As shown in Figure 3, said magnet 31 1 ends are provided with epitaxy part 311, and said epitaxy part 311 structures and patient's 1 shoulder are fitted, be convenient to patient 1 under sprawl shoulder near magnet 31.Said magnet 31 is connected with a liftable supporting mechanism 2, said supporting mechanism 2 and metope support and connection.Magnet can be got into the scanner inspection with the convenient patient's incidence that adapts to by control up-down, translation and arbitrarily angled rotation under different gestures such as seat, semireclining position.Said magnet 31 belows are patient support device 4, and in the present embodiment, said patient support device 4 is the syllogic chaise longue; The supporting head part section of said patient support device 4 is near the magnet arrival end; Said syllogic chaise longue also can cooperate the adjusting of degree of freedom such as rotating, folding according to the position of magnet 31, and after the patient took a seat, head was towards oblique upper; Through up-down magnet 31 and adjusting patient support device 4, make the internal check of the convenient entering of patient's incidence magnet.
Certainly, above superconducting magnet also can replace to the permanent-magnet type magnet.
Because this utility model is integrated in magnet 31 parts with radio-frequency field emission/receiving coil outer ring 32, gradient coil 33 and magnet superconducting coil 34; Dwindled the volume of magnet 31 greatly with coiler part; Then make magnet 31 can under the up-down of supporting mechanism 2, realize the adjusting of position; Make patient 1 be convenient to comfortable acceptance scanning, especially removed claustrophobia patient 1 misery.
Consider the actual demand amount of the special-purpose MR of incidence system, occur same hospital probably and be equipped with the situation that surpasses 1 title neck special machine.Because software, application system design special property strong (incidence scanning only is provided); Can consider to adopt a cover electronics rack and a Control Computer to carry out the control of many scanning systems, operating host can be supported many station terminal visits with scanning back reconstructed image and post processing.As shown in Figure 4; Present embodiment also provides another kind of technical scheme: a kind of magnetic resonance system; Comprise at least two aforesaid magnetic resonance devices 1; 2 ... N, many said magnetic resonance devices are connected with a cover time-sharing control system, time-sharing control system and then connect corresponding n platform and operate and display terminal.When the operator operates said terminal, when transmitting control command to time-sharing control system, time-sharing control system can gating said magnetic resonance device wherein, said magnetic resonance device begins the patient is diagnosed; The data that diagnosis obtains to said terminal, are carried out Flame Image Process through the time-sharing control system reverse transfer.The above can realize having improved resource utilization greatly through many said magnetic resonance devices of a cover time-sharing control system timesharing control, saves the purchase cost of hospital.
Obviously, those skilled in the art can carry out various changes and modification to this utility model and not break away from the spirit and the scope of this utility model.Like this, belong within the scope of this utility model claim and equivalent technologies thereof if these of this utility model are revised with modification, then this utility model also is intended to comprise these changes and modification interior.
