In this work, a novel RF phased array coil for breast imaging was designed, constructed and tested. In the inverse design, an iterative optimization approach was used to determine the coil geometry. The main focus of this study is to design an arracy coil with simple strucure and good RF field profile. Both the simulated and experimental results demostrate the performance of the proposed method in terms of sparsity of the designed coil structure and the improved B1 field.
