Design of high-speed data acquisition system for microwave-induced thermoacoustic tomography used in biological tissue / 医疗卫生装备

ABSTRACT

It is a technological difficulty to acquire data from ultrasound with ultra-band in the study of microwave-induced thermoacoustic tomography. A high-speed data acquisition system for the ultrasonic signal with a frequency fewer than 500 MHz is designed in the paper. The result obtained demonstrates that the system holds good for microwave-induced thermoacoustic tomography.
