An automatic nuclear magnetic resonance imaging system and its detection method

Abstract

The invention provides a nuclear magnetic resonance automatic imaging system and a detection method thereof and belongs to the field of nuclear magnetic resonance imaging. The nuclear magnetic resonance imaging system comprises a base, an open magnet unit, a magnet seat, gradient coils and radio frequency coils. The magnet seat is in a ring form with a rectangular cross section and fixed on the base in a vertical mode. The open magnet unit is two arc magnets, the two arc magnets are symmetrically connected to the same torus of the magnet seat, and the periphery of the inner torus of each arc magnet is provided with the gradient coil and the radio frequency coil. A half-surrounding space formed by each arc magnet, each gradient coil and each radio frequency coil is an imaging area. According to the nuclear magnetic resonance automatic imaging system, an open magnet system is adopted to enable the center space for placing a patient body to be expanded and enable the claustrophobic patient to relax. Symmetrical rotary magnets are utilized to change the directions of magnetic poles to improve the flexibility of the imaging area and to be favorable for precise diagnosis of state of an illness, and an operation platform is arranged on a hospital bed to improve the imaging precision.

Description

technical field [0001] The invention belongs to the field of nuclear magnetic resonance imaging, and in particular relates to an automatic nuclear magnetic resonance imaging system and a detection method thereof. Background technique [0002] Magnetic resonance imaging (MRI, English full name: magnetic resonance imaging) system is often used in the medical and health field, that is, the nuclear magnetic resonance phenomenon occurs when hydrogen nuclei (protons) in human tissues are excited by radio frequency pulses in a magnetic field, and magnetic resonance signals are generated. It is an imaging technology that reconstructs an image of a certain level of the human body through electronic computer processing. [0003] In MRI applications, the patient's body (or object) is usually placed in an imaging area in a barrel-shaped magnet structure, and the imaging area is determined by the design and position layout of the components of the MRI system. One of the problems is that...

Problems solved by technology

One of the problems is that the central space for placing the patient's body is very limited, and since the bed is also placed at the same time, the patient who is lying down is prone to a sense of closure fear

Imaging some extremities, such as the shoulder, can be very difficult, or even impossible in large patients, in order to properly place the part of the patient's body to be imaged within the imaging field
