1results about How to "Consistent Image Quality" patented technology

The application discloses a passive auxiliary resonator and relates to the technical field of medical apparatuses, which comprises a resonant cage structure, a slotted end cover and a spacing field suppressor, one end of the resonant cage structure is connected with the slotted end cover, the other end is open, and a plurality of spacing field suppressors are uniformly distributed along the circumference of the resonant cage structure, the resonant cage structure is used for being sleeved in a birdcage coil of a nuclear magnetic resonance device, and the resonant cage structure is provided with different size models according to the size of a cross-sectional area. The passive auxiliary resonator in the embodiment is placed in a nuclear magnetic resonance cabin for use, can realize substantial enhancement of the radio frequency magnetic field strength in the resonator, and further improves the nuclear magnetic resonance imaging resolution; meanwhile, the radio frequency magnetic field in the resonator is uniformly distributed, so that the imaging quality in the cavity remains consistent with the change of positions; the overall structure does not need to be additionally connected with cables, and the size can be selected and used according to needs, so as to adapt to the nuclear magnetic resonance imaging enhancement of different sizes of human body parts.
