Animal coil special for liver ECS experiment

Abstract

The invention discloses an animal coil special for a liver ECS experiment. The animal coil comprises an upper skeleton and a lower skeleton, the upper skeleton is detachably connected with the lower skeleton, the upper skeleton and the lower skeleton form a cylindrical structure, and antenna units are both arranged in the upper skeleton and the lower skeleton. The antenna unit positioned in the upper skeleton and the antenna unit positioned in the lower skeleton form a radio frequency coil, and a calibration mold is also arranged on the lower skeleton and is located at the side, close to the upper skeleton, of the lower skeleton. A channel for placing animals is formed between the calibration mold and the inner wall of the upper skeleton, and the upper skeleton is an arc-shaped plate. Thecalibration mold and the animal coil are designed together to realize the synchronization of a measurement process and the animal scanning, so that the imaging of a tracer sample solution and a testedobject can be completed at the same time through the one-time scanning, the measurement stability of the system can be monitored in real time, and the subsequent data analysis and comparison are facilitated.

Description

technical field [0001] The invention relates to an animal coil, in particular to a special animal coil for liver ECS experiments. Background technique [0002] The magnetic resonance system is a high-end medical imaging device, and the radio frequency receiving coil is a very important part of the magnetic resonance system. The role of the RF receiving coil in it can be compared to the eyes of an adult, and the final clarity of the image is directly proportional to its signal-to-noise ratio (sensitivity). In order to improve image clarity (or signal-to-noise ratio, or sensitivity), the first principle of general coil design is to make the size of the coil as close as possible to the scanning site or object while satisfying the size of the scanning site or object. Such as the design of a head coil, its size at first will satisfy the head of most patients (such as the patient ratio of more than 95%) can be placed in the coil, but the size of the head coil can not be too large...

AI Technical Summary

Problems solved by technology

However, the existing supporting animal coils can only simply image animals, and cannot image the calibration system (tracer samples with different concentrations), and the calibration system is the key to determine the concentration and amount of the imported tracer Steps, the original design is a single measurement before the experiment, and the synchronization between the measurement process and the animal scan cannot be realized, which is inconvenient for the stability of the real-time monitoring system measurement
