Description

Technical Field

[0001] The utility model relates to the technical field of medical imaging equipment, in particular to an adjustable double-tuned head birdcage coil device. Background Art

[0002] Magnetic resonance imaging technology has become one of the important tools for clinical diagnosis and research in medicine. It has the characteristics of being non-invasive, non-ionizing, and radiation-free. The radio frequency coil is an important component of the imaging system, which plays a vital role in the imaging quality and directly affects the image signal-to-noise ratio.

[0003] The center of the birdcage coil can generate a relatively uniform radio frequency electromagnetic field, so the magnetic resonance system usually uses a birdcage coil as a transmitting coil or a common transmitting and receiving coil. The structure of a traditional birdcage coil device is usually a unified whole. When a problem occurs with a local coil, the entire birdcage coil device needs to be dismantled, repaired or replaced, which is cumbersome and inconvenient. In addition, the head placement area of ​​the traditional birdcage coil device cannot be height-adjusted according to actual usage requirements, which is not conducive to the flexible use of the birdcage coil device. Therefore, it still needs to be improved. Utility Model Content
