Description

Technical Field

[0001] The invention relates to the technical field of magnetic resonance imaging coils, in particular to an animal ex vivo tissue magnetic resonance imaging coil. Background Art

[0002] Magnetic resonance imaging of small animal tissues in vitro has been widely used in many fields such as basic medicine, drug development, cognition and materials science. Small animals such as rats and rabbits are commonly used research subjects in animal experiments because of their strong reproductive capacity and ease of breeding. The lumbar vertebrae, coccygeal vertebrae and knee joints of small animals are often used in the study of the effects of new orthopedic drugs and new materials. However, two technical difficulties were found in the actual scanning: 1. Animal tissues are easy to harden after being isolated and soaked in fixative, making it difficult to maintain the required shape during scanning. For example, when scanning the knee joint, it is generally required that the femur and tibia and fibula be maintained at a 150° angle; when scanning the coccygeal vertebrae, it is required to be straightened as much as possible so that the mouse tail is displayed in the same plane throughout. 2. In order to facilitate the comparison of the different effects of several materials or treatments, it is best to complete multiple samples in one scan. Because if it is two separate scans, even if the sequence parameters are the same, there is pre-scan information such as different signal gains assigned before the two scans, and it is impossible to make comparisons by outlining the region of interest (ROI) measurement.

[0003] When some existing magnetic resonance imaging coils scan animal ex vivo tissues, the object to be detected is often placed in the coil for scanning. However, since the softness and hardness of animal ex vivo tissues vary, and the volume of different tissues also varies, the size requirements of the detection table are also different, and only one ex vivo tissue can be detected at a time. At the same time, when the ex vivo tissue is sent into the coil, the existing mechanism is prone to position changes and cannot maintain the predetermined shape. Summary of the invention

[0004] The object of the present invention is to provide an animal ex vivo tissue magnetic resonance imaging coil to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0014] Preferably, the imaging coil assembly comprises a coil housing, on which four positioning plates and four additional plates are arranged, and each of the additional plates is provided with a plug-in rod, and each of the positioning plates is provided with a supporting screw.

[0015] Preferably, a pouring box is detachably connected to the upper surface of the material placing assembly;

[0016] Preferably, the perfusion box is provided with a shell, the shell wall of the shell is a hollow cavity structure, and the outer wall of the shell is respectively provided with a liquid inlet and a liquid outlet, and the liquid inlet and the liquid outlet are both connected with the shell wall cavity of the shell; a sample fixing plate is provided inside the perfusion box, and the upper surface of the sample fixing plate is provided with at least one handle; at least two fixing holes; at least one liquid discharge pipe is also provided on the outer wall of the shell, and the liquid discharge pipe is connected with the inside of the perfusion box.

[0022] The setting of the perfusion box is aimed at the in vitro tissues of small animals such as rats and rabbits. After being filled with magnetic field compensation liquid, the problem of being unable to generate resonance signals due to the small volume of the in vitro tissues is solved. At the same time, the setting of the sample fixing plate is convenient for fixing the position of small and irregularly shaped samples such as rat tails and spines, and multiple or various animal in vitro tissues can be fixed on the sample fixing plate at the same time, which is convenient for imaging and improves detection efficiency and clarity.
