Research Abstract

The importance of the quantification of tissue elasticity has increased using shear elastic wave because of screening and diagnosis of the cancer. We developed high-PRF 5GHz MIMO radar system for a Microwave Elasticity Imaging. The numerical simulations were carried out in order to localize the independent shear wave scatterers using time reversal MUSIC algorithm with circular array. It implies that the scatterers having the radius of 3 mm and vibration amplitude of 10μm can be measureable using a 9×9 MIMO radar system with the circular array having the radius of 2cm
