Title:
METHOD AND APPARATUS FOR DETERMINING LOSS MODEL OF RADIO FREQUENCY TRANSMITTING COIL, AND DEVICE AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/185116
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present application are a method and apparatus for determining a loss model of a radio frequency transmitting coil, and a device and a medium. The method comprises: obtaining first index data of at least two evaluation indexes of scattering parameters of each of at least one transmitting channel of a radio frequency transmitting coil of a magnetic resonance system in an actual measurement environment; connecting an equivalent resistor in parallel or in series for each circuit component of a virtual radio frequency transmitting coil so as to establish a loss simulation model; and adjusting an equivalent resistor and a matching capacitor of each transmitting channel in the loss simulation model to enable an error between second index data of the at least two evaluation indexes of the scattering parameters of each transmitting channel in the loss simulation model after adjustment and the corresponding first index data to be within a corresponding threshold range so as to obtain a loss model of the radio frequency transmitting coil.
