Abstract

A method for spatial-velocity imaging of nonrigid moving targets, such as the human heart, which utilizes a quasi-monostatic phased array or a bistatic phased array that illuminates the target scene with a continuous-wave large-bandwidth signal and simultaneously records the Doppler-shifted echoed signals is presented. The imaging system utilizes an inverse solution for phased array imaging that incorporates the spectral distribution of an element's radiation pattern and it does not put any restrictions on the irradiating signal and the target scene. The system is applicable in near field as well as far field imaging problems of diagnostic medicine involving the human cardiovascular system.
