Cable-less transducers

Yes, you read that correctly!  Several manufacturers are making ultrasound systems with cable-less (wireless) transducers.  

The transducers are a little bulkier than standard transducers because they must house a transmitter to wirelessly send the echo data to the receiver in the main unit.  However, I can guarantee you that these cable-less transducers will become smaller over time.  For an example, check out the Clarius system here
