Abstract

A medical diagnostic ultrasound system is provided which is portable and capable of being carried by a built in handle from location to location by single person. The system is provided in a package which is both light and compact. Further, a medical diagnostic ultrasound system is provide in which the circuitry of the ultrasound system is distributed among several circuit boards which are interconnected directly with one another without the use of a backplane or motherboard.
