Magnetic resonance spectrometer and scanning method and radio frequency transmitting and receiving method thereof

Abstract

The invention provides a magnetic resonance spectrometer and a scanning method and a radio frequency transmitting and receiving method thereof. The magnetic resonance spectrometer comprises a router, a computer unit and a hardware implementation unit. The computer unit comprises multiple computer modules. The hardware implementation unit comprises multiple hardware implementation modules. Multiple first optical ports are configured on the router. The multiple first optical ports are connected with the computer modules or the hardware implementation modules through optical fibers in a one-to-one correspondence way. The router receives data packets transmitted by the computer modules and forwards the data packets to the hardware implementation unit or other computer modules. The router receives the data packets transmitted by the hardware implementation unit and forwards the data packets to the computer unit. The computer unit and the hardware implementation unit are connected through the router to form an optical fiber communication topology network so that the system working efficiency of the magnetic resonance spectrometer can be enhanced, the system reliability can be enhanced and the overall scanning speed can be accelerated.

Description

technical field [0001] The present disclosure relates to the field of medical equipment, in particular to a magnetic resonance spectrometer, a scanning method thereof, and a radio frequency transmitting and receiving method. Background technique [0002] Magnetic resonance imaging (magnetic resonance imaging, MRI) uses a constant magnetic field generated by a magnet to excite the subject through a radio frequency system and a gradient system to generate magnetic resonance signals, and then collects and reconstructs the signals through the receiving system to obtain the subject's Method of specimen image. [0003] A magnetic resonance spectrometer is a device for realizing magnetic resonance imaging. In related technologies, a magnetic resonance spectrometer usually includes a control module, a computer unit connected to the control module for functions such as scanning and reconstruction, and various hardware execution units, wherein, The control module is based on the back...

Problems solved by technology

[0004] With the development of magnetic resonance imaging, the communication requirements between the computer unit and the hardware execution unit are getting higher and higher. When the existing control bus is used for communication, the control module can only access one hardware execution unit at a time, so the communication efficiency is relatively high. Low; and limits the scalability of the MR spectrometer due to the limited number of interfaces that the control bus can support
