Abstract

The invention discloses a magnetic resonance spectrometer and a magnetic resonance imaging system. The magnetic resonance spectrometer comprises a micro-control unit which communicates with a gradient signal generation board, a radio frequency pulse signal generation board and a receiver and is used for controlling operation of the gradient signal generation board, the radio frequency pulse signal generation board and the receiver through data sent by an upper computer and sending magnetic resonance signals obtained by the receiver to the upper computer, wherein the radio frequency pulse signal generation board is used for sending a pulse signal to a radio frequency general coil to excite the radio frequency general coil to generate a radio frequency magnetic field so as to enable a detected object to generate a magnetic resonance phenomenon, the radio frequency pulse signal generation board is provided with at least two radio frequency emission sources and a detection module used for detecting a radio frequency energy deposition value, and the receiver is used for receiving magnetic resonance signals of a radio frequency receiving coil. With the magnetic resonance spectrometer and the magnetic resonance imaging system of the invention adopted, the problems of poor imaging quality and potential safety hazards of a high-field magnetic resonance imaging system in the prior art are solved.

Description

technical field [0001] The present application relates to the technical field of magnetic resonance, in particular, to a magnetic resonance spectrometer and a magnetic resonance imaging system. Background technique [0002] The magnetic resonance signal strength is directly proportional to the magnetic field strength. Therefore, increasing the main magnetic field strength is an effective method to improve the signal-to-noise ratio of the magnetic resonance imaging system in the field of magnetic resonance imaging technology, and it is also the most commonly used method. [0003] It should be noted that 3T and above high-field magnetic resonance imaging systems are developed based on the above principles. Studies have shown that high-field magnetic resonance at 3T and above has obvious advantages in signal-to-noise ratio, and can achieve structural imaging with 0.1mm isotropic resolution. However, although the high-field MRI system has significant advantages in principle, th...
