Description
Technical field
The present invention relates to magnetic resonance arts, more particularly to magnetic resonance local coil base, local coil component and ankle
Coil block.
Background technology
Magnetic resonance imaging (Nuclear Magnetic Resonance Imaging, abbreviation NMRI), also known as spinning into
As (spin imaging), also referred to as magnetic resonance imaging (abbreviation MRI) is to utilize nuclear magnetic resonance principle, according to the energy for being discharged
The different decay in different structure environment inside material, launched electromagnetic wave is detected by additional gradient magnetic, is drawn
Go out the structural images of interior of articles.
MRI system includes magnet system and computer picture reconstructing system, and magnet system includes magnetostatic field, gradient fields and penetrates
Display system.Magnetostatic field：Also known as main field, superconducting magnet used by Present clinical, magnetic field intensity has 0.5 to 4.0T (tesla), often
That see is 1.5T and 3.0T；It is another to there is unifluxor circle (shim coil) to assist to reach the high evenness in magnetic field.Gradient fields：For producing
The gradient in magnetic field is given birth to and controls, to realize the space encoding of MRI signal.This system has three groups of coils, produces x, y, z three
The gradient fields in direction, the magnetic field superposition of coil group is got up, and can obtain the gradient fields of any direction.Radio system occurs including radio frequency
Device and radio frequency receiver, radio-frequency signal generator produce short and strong radiofrequency field, are added on sample in a pulsed fashion, make the hydrogen in sample
Core produces NMR phenomenons；Radio frequency receiver：NMR signal is received, image processing system is amplified into.
The signal that computer picture reconstructing system is sent by radio frequency receiver is converted into analog signal through A/D converter
Digital signal, according to the corresponding relation with observation each voxel of aspect, is processed through computer, draws layer images data, then through D/A
Converter, is added on image display, by the size of NMR, the image of aspect to be observed is shown with different tonal gradations.
The coil of magnetic resonance scanner can be classified as radio-frequency coil, receiving coil and gradient line according to its effect difference
Circle.Described coil typically refers to the reception for receiving magnetic resonance signal of the human body produced by imaging position in clinical position
Coil.Some coils have transmitting and receive dual-use function simultaneously.Coil directly decides image quality, and its performance is very big
Set when being dispatched from the factory in degree.The image for wanting to obtain high s/n ratio using existing coil must just increase the tissue for receiving
Magnetic resonance signal, reduces noise.Also the noise of tissue generation is received while coil collection is by imaging position magnetic resonance signal, and
The size of noise is relevant with the tissue volume contained by coil, and contained tissue is fewer, and noise is smaller.Meanwhile, the contained tissue of coil holds
Long-pending size also determine the H proton contents for participating in imaging.Coil should try one's best and be adjacent to scanned position, make its spacing minimum, to increase
The MR signal intensities that adjunction is received, reduce the noise for receiving.Therefore, should be according to the size choosing of the scanning region of anatomy when from coil
Selecting can cover the minimum coil of the region of anatomy with patient's tight fit.
Conventional coil can use flexible coil or special ankle coil when clinic is scanned imaging to ankle.Use
Because parcel is incomplete when flexible coil is wrapped up ankle, it is impossible to obtain toe portion signal, at the same can cause sole with
Shank at an angle, does not meet the observation of human body standard anatomy posture in sagittal plane.
And the special usual coil unit of ankle coil cannot cover whole foot, such as heel position usually not coil
Unit.Therefore certain signal to noise ratio can be lost so that imaging effect is not good enough.Some special ankle coils are in upper and lower folding simultaneously
Structure, it is impossible to be accurately positioned to ankle in a scan, and cause coil top half heavier.Therefore in operation, open
Close top and the bottom more inconvenient.Then there is unit top and the bottom to another ankle coil, but because this ankle coil is logical
Often shared with knee coil, fitted with foot in bad order, and cannot be in sole distribution unit, to gather magnetostatic field direction
Signal, therefore coil entirety signal to noise ratio can be caused to decline.
Meanwhile, most of ankle coil is all difficult to move after fixing, it is impossible to for the clinic of ankle varus and valgus
Demand provides suitable pendulum position, it is impossible to meet the certain applications scene of actual clinical.
