Synopsis

Keywords: RF Pulse Design & Fields, RF Arrays & Systems

Motivation: There is a lack of tools for predicting the component values for such irregular wireless volume coils.

Goal(s): The goal is to propose a novel co-simulation method that accurately predicts the capacitance distribution of irregular volume coils.

Approach: We validated this method using various shapes of irregular volume coils, including bottle-shaped, dome-shaped, and elliptical coils, at both 1.5 T and 3 T.

Results: The consistency between the simulated and practical capacitance further confirms the accuracy and reliability of the proposed probe-based co-simulation methods.

Impact: This co-simulation method can guide fabricating wireless irregular volume coils and can be extended to other types of wireless coils.
