Magnet coil framework of magnetic resonance medical instrument

Abstract

The invention discloses a magnet coil framework of a magnetic resonance medical instrument. The magnet coil framework is characterized by comprising an inner framework and two outer frameworks, wherein the inner framework comprises a cylinder body and multiple layers of non-metallic materials coiled on the outer wall of the cylinder body; a plurality of first annular linear slots which are axially distributed on the cylinder body are formed in the multiple layers of non-metallic materials; each outer framework comprises a disc body and multiple layers of non-metallic materials coiled on the outside wall of the disc body; a round hole matched with the cylinder body is formed in the bottom of the disc body; a second linear slot is formed in the non-metallic materials; the two outer frameworks are connected to two end parts of the cylinder body in the inner framework through the through holes in the disc bodies; and the cylinder body is located inside the disc bodies of the two outer frameworks. The provided magnet coil framework adopts the non-metallic materials, the weight is reduced, and the cost is reduced greatly.

Description

Technical field [0001] The invention relates to a magnetic resonance medical instrument, in particular to a magnet coil skeleton of the magnetic resonance medical instrument. Background technique [0002] At present, the MRI medical instrument is widely used in the medical field, which uses MRI technology to check whether the patient is sick. The basic principle of nuclear magnetic resonance is to place the human body in a special magnetic field and use radio frequency pulses to excite hydrogen nuclei in the human body, causing the hydrogen nuclei to resonate and absorb energy. After the radio frequency pulse is stopped, the hydrogen nucleus emits radio signals at a specific frequency and releases the absorbed energy, which is collected by a receiver outside the body, and processed by an electronic computer to obtain an image, which is called nuclear magnetic resonance imaging. Nowadays, the commonly used magnetic resonance frameworks are all made of metal materials and light me...
