In this work a comparative design study for the development of a new proton (¹H) transmit/receive radio frequency (RF) coil for unilateral breast imaging at 3 Tesla (123MHz) is performed. The two most common RF breast coil designs, based on quadrature and solenoid coils, are compared against each other in terms of spatial homogeneity and first-order statistics (mean µ, standard deviation σ, spread σ/µ) of the circularly polarized RF excitation field (B₁⁺) as well as B₁⁺ scaled over the square root of the maximum 10g-averaged specific absorption rate (B₁⁺/√(SAR_peak)).
