Problems solved by technology

However, the existing radio frequency coils are rarely designed to be compatible with multi-modal imaging methods. In order to obtain a higher signal-to-noise ratio, most radio frequency coils are used close to the scalp of small animals. The small space makes the probes, electrodes and other devices inaccessible. small animal head

Embodiment 1

[0059] Figure 1 to Figure 11 Shown in a preferred embodiment of this helmet-type primate radio frequency coil of the present application, it is mainly made up of animal holder 1, four universal connecting rods 2, coil support shell 3, radio frequency receiving coil 4 and signal wire 5 and so on, including:

[0060] The animal holder 1 is used to fix the tested animal—usually a monkey.

[0061] The coil supporting shell 3 is a helmet-shaped structure adapted to the head of a primate, which has a head accommodation chamber for accommodating the head of the animal to be measured, and can be worn on the head of the animal to be measured, so as to The radio frequency receiving coil 4 acquires the brain image of the tested animal. The coil supporting shell 3 is mainly used to support and protect the radio frequency receiving coil 4 inside.

[0062] The radio frequency receiving coil 4 is fixed inside the coil supporting shell 3, which is the core component of magnetic resonance ...

Embodiment 2

[0108] Figure 12 and Figure 13 Another specific embodiment of the helmet-type primate radio frequency coil of the present application is shown. The structure of the coil device is basically the same as that of the coil device in Embodiment 1, the main difference is only in:

[0109] The radio frequency receiving coil 4 in the coil supporting shell 3 is only composed of 6 coil units. Because the imaging quality of these 6 coil units is inferior to that of the 16 coil unit radio frequency receiving coils in Embodiment 1, and there is no special bright spot compared to the distribution of the 6 coil units in Embodiment 1, so it will not be repeated here. .

[0110] There are only two rod clamps 105, which are connected with two guide rods 101 respectively. Correspondingly, only two universal connecting rods 4 are configured.

Abstract

The invention discloses a helmet-type primate radio frequency coil for multi-mode magnetic resonance imaging. The helmet-type primate radio frequency coil comprises a helmet-type coil supporting shell capable of being worn on the head of a measured animal and a radio frequency receiving coil arranged in the coil supporting shell, wherein a plurality of test holes for inserting data acquisition equipment are formed in the coil supporting shell in a penetrating manner. According to the helmet-type primate radio frequency coil, images or data of other imaging modes can be acquired while magnetic resonance images are acquired, the coil has higher magnetic resonance imaging quality, and damage to animal body tissues in the imaging process can be avoided.

Description

technical field [0001] The present application relates to the field of magnetic resonance imaging, in particular to a helmet-type primate radio frequency coil for multi-modal magnetic resonance imaging. Background technique [0002] In medical clinical research and neuroscience research, small animals have become an important model for studying the structure and function of the human body, especially non-human primates such as rhesus monkeys and marmosets. However, most of the magnetic resonance imaging systems used in research are for clinical use, and the existing radio frequency coils are also difficult to meet the needs of practical use. Therefore, the design of radio frequency coils for small animals provides the possibility of imaging small animals under clinical magnetic resonance systems. In addition, in recent years, in various researches related to magnetic resonance imaging, there has been an increasing demand for multimodal imaging methods. People expect to acqui...
