Description
Technical field
The present invention relates to a kind of device for integrated nmr magnet and probe.
Background technology
Nuclear magnetic resonance (Nuclear Magnetic Resonance, be called for short NMR) refer to the atomic nucleus of non-zero magnetic moment main field is vertical with radio-frequency field act under, spin energy level generation Zeeman splitting, atomic nucleus absorbs a kind of physical process of radio-frequency (RF) energy, numerous advantages that other detection means such as have Non-Destructive Testing, Detection Information enriches is incomparable.
Monolateral nuclear magnetic resonance device, early stage general volume is still heavier, instead of portable, can only be referred to as portable.The Topspin Medical company of Israel have developed a packaged type NMR imaging device, based on inside-out design philosophy, for cardiovascular disease diagnosis, during detection nmr probe be directly deep into human vas inside signals collecting is carried out to diseased region, signal after collection is transferred to the nuclear magnetic resonance electronic control system outside human body through cable, and is stored into further in computing machine and carries out data processing and image display analysis.The probe of this device is integrated with Micro Magnet and micro radio-frequency coil, and the Micro Magnet of probe can produce gradient magnetic around it, and therefore this device no longer needs extra gradient coil to carry out imaging analysis.Bernhard Bl ü mich research group of Aachen, Germany polytechnical university proposes the concept of portable nuclear magnetic resonance general purpose table surface detector, the method adopted is that the semi-cylindrical permanent magnet first two being divided into mutually 13 mm is embedded in yoke, produce 0.5 T main field, again the solenoid coil of four layer of eight circle is embedded into be arranged in interstitial area and the adhesive of nonmagnetic impact, form the integration probe of monolateral nmr sensor, integration probe net weight is 2.5 Kg only; Integration probe just forms magnetic resonance detection system after connecting diplexer, prime amplifier, electronic housing and computing machine, can move integration probe, be placed in above body surface and detect in experimental work.NMR MOUSE is mainly used in material composite coarse evaluation, and the water cut as rubber tyre, solid polymer, soil and seed detects etc.The proposition of nuclear magnetic resonance MOUSE, greatly reduces the cost of magnetic resonance detection equipment.Miniaturization and the portability direction of monolateral nuclear magnetic resonance device are started.
Nuclear magnetic resonance technique range of application is very wide, covers the various fields such as biology, medical science, chemistry, food, oil, polymkeric substance, safety check, building and the artwork.But traditional nuclear magnetic resonance equipment, bulky, manufacture and maintenance cost high, seriously limit its widespread use.Existing nuclear magnetic resonance device manufacturer, as being in the German BRUKER company of rank first in this field, although their series of products minispec mq series can realize detecting, but its volume ratio is heavier, the running of whole device and in-site installation are very difficult and complicated, this, by greatly limiting the exploitativeness of movable operation, thing Site Detection to be checked, is difficult to the demand meeting field monitoring.

In such scheme, permanent magnet by fixed mount load-bearing, and assists location by the bracing frame of both sides, fixed mount and bracing frame are fixed by round and smooth slotted eye, the fixed position of adjustable permanent magnet, guarantee that installation is suitable, insert holding screw in bracing frame, keep fixing with fixed mount.
In such scheme, probe cavity is used for shield electromagnetic interference, detachably, for placing nmr probe, and ensures that probe cavity is positioned at the center of permanent magnet by P.e.c. grillage.
In such scheme, probe cavity and P.e.c. grillage cooperation place is fluted, is used for arranging the lead-in wire of nmr probe, facilitates and the welding of printed circuit board (PCB).
In such scheme, P.e.c. grillage one end supports probe cavity, other end fixed printed circuit board, and is fixed on base by round and smooth slotted eye, guarantees that installation is suitable.
In such scheme, base is made up of magnet support part and probe support part, is convenient to dismounting, assembling and moves.
In such scheme, this device is except permanent magnet, and all parts all adopt aluminium material to make, and spray paint through blackening process and insulation, and to reach, device is light, antirust, the object of insulation.
(3) beneficial effect
The present invention is reasonable in design ingenious, and permanent magnet required when being worked by nuclear magnetic resonance device and probe are fixed in the middle of a device, and compact conformation stability is comparatively strong, has applied widely, and mobility is strong, easily assembled quick advantage.
Except permanent magnet in the present invention, all parts all adopt aluminium material to make, and spray paint through blackening process and insulation, and insulate antirust, device is light, cheap.
