Interventional magnetic resonance receiving coil component and magnetic resonance equipment.
Background technology
Magnetic resonance system is a kind of equipment for medical imaging diagnosis, clear, accurate human dissection which can provide
Learn image.The cardinal principle of magnetic resonance system is as follows：Atomic nucleus in magnetic field are swashed in the of short duration electromagnetic wave for being subject to certain frequency
After sending out, the electromagnetic wave signal with stimulating frequency equal frequencies is sent, this signal is gathered and be sent at signal by receiving coil
Reason equipment (such as computer), forms image after treatment.
Minimally invasive intervention operation in, preoperative need to carry out prescan using nuclear magnetic resonance, NMR to operative site, in order to plan
The epidermis insertion point of pin (or thorn, bar etc.), the hand-manipulating of needle path and target position etc. such as (or thorn, bar).The path of physician in view planning
Will be inserted into the patient for pin (or thorn, bar etc.).Corrective surgery position is scanned again by NMR system, with check pin (or
Thorn, bar etc.) position whether accurate.For the receiving coil that MR-guided interventional operation is used, operative site is usually required that
Partial sweep imaging mass ratio higher, and for operative site outside image quality requirements relatively low.In magnetic resonance system,
Transmitting coil component is diverse with the mentality of designing of receiving coil component, thus belongs to two different fields.
In magnetic resonance imaging, patient position to be scanned and receiving coil imaging region should be in the homogeneity ranges in magnetic field
Interior.In MR-guided interventional operation, position of the patient position to be scanned in magnetic field can be adjusted by motion scan bed, come
It is in the homogeneity range in magnetic field.But, if receiving coil imaging region is inconsistent with patient position to be scanned, need by
Scanning bed removal magnet, then moves patient and readjusts.This causes procedure efficiency to be greatly reduced.Additionally, postanesthetic patient
Mobile inconvenience, which increases operating difficulty.Therefore, it can realize repositioning by moving coil.
For example, CN201398969Y discloses a kind of MR imaging apparatus with movable body coil, the magnetic resonance
Imaging device includes a magnet for producing stable main field, the gradient coil of the gradient fields of a generation quick on-off,

Circle is integral with MR imaging apparatus setting, and the body coil is movably disposed in a supporting construction, and can
Longitudinally it is movable into and out inside the magnet along the magnet by the supporting construction.The supporting construction of the patent documentation is to stretch
Contracting connecting rod, it is impossible to realize that receiving coil is accurately positioned.
For another example, CN104055517A discloses a kind of MR imaging apparatus, including：Sick bed, for disposing patient；Positioning
Unit, for controlling movement and the positioning of the sick bed；Body radio-frequency coil, for launching and receiving radiofrequency signal；Local coil,
The local coil includes：Fixed coil device, below the sick bed, for covering the back of the body for being currently needed for the part that scans
Face receives radiofrequency signal；Movable coil device, above the sick bed, the movable coil device includes：Radio frequency connects
Take-up circle, for receiving radiofrequency signal；Mechanical arm, is currently needed for the part that scans for moving the RF receiving coil laminating
Front.The MR imaging apparatus move receiving coil using mechanical arm, do not have other auxiliary to arrange, increased and be accurately positioned
Difficulty.
