Abstract

A diagnostic ultrasound apparatus is disclosed comprising a base board, an ultrasonic front-end analog circuit, a digital processing circuit connected with the ultrasonic front-end analog circuit, and a power module for providing electric power to the ultrasonic front-end analog circuit and the digital processing circuit. The ultrasonic front-end analog circuit is implemented with a modular design, the digital processing circuit and the power module being located at one half-region of the base board, and the ultrasonic front-end analog circuit being located at the other half-region of the base board. The ultrasonic front-end analog circuit is provided far away from the power module and the digital processing circuit such that interference from the power supply and digital circuits is prevented.
