An Egg Radio Frequency Coil Device for Magnetic Resonance Imaging

Abstract

The invention discloses an egg radio frequency coil device used for magnetic resonance imaging. The device comprises a support, a supporting column and a radio frequency coil mechanism. The device is characterized in that the supporting column is installed on the center position of the support; a recessed hole is formed at the central position of the supporting column; a cavity is arranged between the outer surface of the supporting column and the surface of the recessed hole; the radio frequency coil mechanism is installed in the cavity; the radio frequency coil mechanism comprises annular coils and saddle-shaped coils; the number of the annular coils is not smaller than three; and the number of the saddle-shaped coils is not smaller than one. With the device adopted, a to-be-tested egg can be placed steady, and the eggshell of the to-be-tested egg can be prevented from being damaged, and therefore, an egg embryo can grow continuously, and subsequent related research can be performed. A four-channel radio frequency circuit formed by the annular coils and the saddle-shaped coils can realize an efficient signal reception effect, the high signal to noise ratio and high resolution of the coils can be ensured.

Description

technical field [0001] The invention relates to the technical field of magnetic resonance imaging, in particular to an egg radio frequency coil device for magnetic resonance imaging. Background technique [0002] The magnetic resonance imaging MRI system uses a uniform strong magnetic field from the main magnetic system B0 to polarize the spins of the hydrogen nuclei in the imaging body, and the magnetically polarized nuclei spins generate a magnetic moment i in the human body, and the magnetic moment i points to The direction of the main magnetic field yields no useful information if there is no excitation perturbation. [0003] The nuclear magnetic resonance signal NMR is generated by a uniform radio frequency RF magnetic field to excite the magnetic moment, so as to obtain the MRI data of the magnetic resonance imaging system. The radio frequency RF magnetic field is called the excitation magnetic field or the B1 magnetic field. A B1 magnetic field is generated in the im...

Problems solved by technology

However, due to the special shape of the egg and the small three-dimensional size, it is difficult to perform high-quality MRI imaging on the egg with the existing coils, even the commonly used animal experiment coils such as rabbits and mice.
