摘要： A diagnostic ultrasound system capable of electronically controlling a beam width not only in a scan direction but also in a slice direction orthogonal to the scan direction despite a relatively small circuit scale. The system is provided with an ultrasonic probe having a plurality of ultrasonic transducers arranged two-dimensionally, and a transmitting/receiving unit for use in scanning an ultrasonic beam, which is transmitted and received by selectively driving the ultrasonic transducers, in the scan direction, and focusing the ultrasonic beam in the slice direction. A driving signal is supplied in common to a plurality of transducers elements adjoining in the slice direction. An echo signal converted by transducers is not only subjected to control of a specified delay time in the scan direction but also received in time sequence and then subjected to control of at least a specified delay time in the slice direction. The echo signal thus-processed is produced into an ultrasound image.
