Problems solved by technology

[0003] When the traditional magnetic resonance device uses the spectrometer system to monitor the radio frequency system, it needs to manually record the phase measurement data and manually calculate the phase error value. The measurement process of manually connecting the equipment, switching channels, and recording the measurement data is complicated and time-consuming. Unable to automate measurements

Embodiment Construction

[0029] Embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0030] figure 1 A flow chart of a test method based on a magnetic resonance spectrometer provided by an embodiment of the present invention is shown. Such as figure 1 As shown, the method includes steps 101-103.

[0031] Step 101: Send out multiple transmit signals at intervals by the transmit chain, and receive multiple corresponding receive signals by the receive chain.

[0032] Among them, the radio frequency system includes a transmission chain and a reception chain. The transmission chain is used to send the transmission signal, and the reception chain is used to receive the corresponding reception signal. The signal (transmission signal, reception signal) can usually be a radio frequency pulse signal, a magnetic resonance signal, etc. In a magnetic resonance system, a magnetic resonance spectrometer (also referred to as a sp...
