Hyper-polarized gas human lung imaging coil for multi-nuclear magnetic resonance system

Abstract

The invention provides a hyper-polarized gas human lung imaging coil for a multi-nuclear magnetic resonance system. The coil comprises a coil plug, an upper coil part and a lower coil part. The uppercoil part comprises an upper coil wrapping layer and a plurality of upper flexible coil units arranged in the upper coil wrapping layer, and the plurality of upper flexible coil units are arranged anddistributed in sequence. The lower coil part comprises a lower coil wrapping layer and a plurality of lower flexible coil units arranged in the lower coil wrapping layer, and the lower flexible coilunits are sequentially arranged and distributed. The coil is high in sensitivity, high in universality for patients with different body types and convenient to install and use.

Description

Technical field[0001]The invention relates to the field of multi-nuclear magnetic resonance imaging, belonging to hyperpolarized noble gas lung magnetic resonance imaging technology, and specifically relates to a hyperpolarized gas human lung imaging coil used in a multinuclear magnetic resonance system, which is suitable for human lung disease inspection And early diagnosis.Background technique[0002]Magnetic resonance imaging (MRI, Magnetic Resonance Imaging) has been widely used in medical diagnosis and research. At present, the main clinical use is the proton magnetic resonance instrument, which works based on hydrogen atoms (protons) in the human body. Proton magnetic resonance imaging can perform structural and functional imaging of most tissues and organs of the human body. However, the proton magnetic resonance system is weak in the detection and diagnosis of lung diseases. Since the density of hydrogen nuclei in the lungs is about 1,000 times lower than that of other tissues...

AI Technical Summary

Problems solved by technology

In order to improve the sensitivity, this coil adopts a close-fitting package design. The disadvantage is that it is necessary to choose coil models of different sizes and specifications for patients of different sizes.

[0006] In general, the existing coils have the following problems: the lung imaging coil composed of a dedicated transmitting coil and a multi-channel phase array receiving coil has good imaging quality, but is bulky and expensive

The transmit-receive shared coil with a higher fill factor can have better sensitivity while being small in size and light in weight, but a set of devices cannot adapt to the application of patients of different sizes

At present, there is a lack of a lung imaging coil that is good in size versatility, sensitivity, and volume and weight
