Specimen fixing device, specimen scanning device and specimen storage device

Abstract

The invention relates to the technical field of magnetic resonance imaging, in particular to a specimen fixing device, a specimen scanning device and a specimen storage device. The specimen fixing device comprises a fixing frame, wherein the fixing frame is provided with a head fixing piece, a limbs fixing piece, a trunk fixing piece and a tail fixing piece. The specimen fixing device can be usedfor fixing a specimen. During transfer of the specimen, no other tools are needed, and only the specimen fixing device and the specimen are transferred together, thus effectively avoiding damage to the specimen. The specimen scanning device comprises a liquid storage bottle, wherein a slot is formed in the liquid storage bottle; the specimen fixing device can be inserted into the slot. By adoptingthe specimen scanning device, the specimen is prevented from being separated from a solution during scanning, the specimen is prevented from floating in the solution, and motion artifacts during magnetic resonance imaging are avoided. The specimen storage device comprises a liquid storage box, wherein a plurality of slots are formed at intervals along the length direction of the liquid storage box; the specimen fixing device can be inserted into the slots; a plurality of specimens can be stored at the same time.

Description

technical field [0001] The invention relates to the technical field of nuclear magnetic resonance imaging, in particular to a specimen fixing device, a specimen scanning device and a specimen storage device. Background technique [0002] Small animal nuclear magnetic resonance is very suitable for the morphological study of various animal specimens due to its high spatial resolution, good soft tissue imaging effect, and the ability to reconstruct scanned tissues in a non-destructive manner. In the prior art, the specimens are usually stored directly by soaking in a storage bottle filled with formalin solution. When the specimen needs to be scanned, a tool is needed to transfer the specimen from the storage bottle to the scanner. Finally, it is necessary to transfer the specimen from the scanning device back to the storage bottle with the help of tools again, and irreversible damage is easily caused to the specimen during the above-mentioned transfer process, making the speci...

Problems solved by technology

In the prior art, the specimens are usually stored directly by soaking in a storage bottle filled with formalin solution. When the specimen needs to be scanned, a tool is needed to transfer the specimen from the storage bottle to the scanner. Finally, it is necessary to transfer the specimen from the scanning device back to the storage bottle with the help of tools again, and irreversible damage is easily caused to the specimen during the above-mentioned transfer process, making the specimen again will cause waste of time and cost, and more importantly, it will affect the experimental results. progress

[0003] In addition, if the scanning is performed together with the storage bottle, since the animal specimens freely float in the solution, motion artifacts will be caused during MRI. At the same time, the morphology of the specimens will change during multi-modal imaging, resulting in high complexity of image fusion.
