Abstract
Apparatus for echo mode imaging of a blood vessel is disclosed having a plurality of transducers that transmit a substantially unfocused omni-directional signal in at least one plane towards the vessel. The reflected signal is received and transmitted in time multiplexed form to an Analog-to-Digital converter. Thus the required number of interconnecting wires is reduced. A method for imaging a blood vessel comprises transmitting an unfocused signal in a substantially omni-directional manner in at least one plane, receiving reflections from the vessel, and transmitting the received signals in time multiplexed form for imaging.
