Abstract

A homogeneity coefficient (HC) is suggested allowing quantitative evaluation of SAR distribution homogeneity over the heated area. Its efficacy in appreciation of SAR patterns quality is demonstrated on idealized and real SAR distributions. The HC parameter of a series of applicators widely used in clinics are calculated. HC could be assumed as a useful parameter additional to the qualified effective field size (EFS) in characterizing the applicator's properties.
