Abstract

The invention discloses a special magnetic resonance imaging device for a baby. The special magnetic resonance imaging device comprises a magnetic resonance imager, a filter board (20), a control device, a software system and a display system. The magnetic resonance imager consists of a superconducting magnet (1), a radio frequency system (2), a gradient system (7) and a patient supporting system (3). The superconducting magnet (1) comprises a superconducting magnetic field coil (5), a driving and driven shimming system (6) and a refrigerating system (4). The diameters of the inner walls of the superconducting magnetic field coil (5), the driving and driven shimming system (6) and the gradient system (7) are sequentially arranged in descending order. The refrigerating system is a classified refrigeration cycle system. By the adoption of the structure, the magnetic field is uniform; and the temperature variation is smooth and the environment is stable by the space positioning of a magnetic resonance imaging system signal and the two-stage refrigeration cycle system.

Description

technical field [0001] The present invention relates to a magnetic resonance imaging device, in particular to a magnetic resonance imaging device for infant examination. Background technique [0002] At present, magnetic resonance imaging is an important means of diagnosing human diseases. It can provide clear images of human tissue through scanning. Compared with other diagnostic methods, its magnetic resonance imaging system not only has no ionizing radiation but also has high definition, which can provide doctors with More accurate disease information. In addition, among the many non-invasive medical images today, magnetic resonance imaging is widely used in medical diagnosis because it is non-radiative, has high spatial resolution, can provide better image data, and has high tissue recognition. There is a high degree of dependence, and hospitals around the world have been or will soon be equipped with magnetic resonance imaging systems designed for adults. [0003] Amo...
