DESCRIPTION:Tomographic reconstructions rely on the acquisition of data fr
 om many sensors that surround an object and a source that illuminates the 
 object from a range of different angles. An ultrasound transducer can act 
 both as source and sensor and therefore arrays of ultrasonic transducers c
 an be used for tomographic reconstructions. However\, a key problem is the
  acquisition of high fidelity signals with adequate signal to noise ratio 
 (SNR) from each transmitter-receiver path so that transmission energies ca
 n be reduced avoiding potentially excessive power transmission and enablin
 g data acquisition without cross talk to other channels (transmitter-recei
 ver paths). This talk will present some of the work that we have done on h
 ow to use coded excitation to simultaneous transmit and receive signals on
  all channels of an array while also reducing the transmission power and m
 aintaining a good SNR in the resulting signals.&nbsp\;
