RNTW02 - Rich and non-linear tomography in medical imaging, materials and non destructive testing

Tomographic reconstructions rely on the acquisition of data from 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 can 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 can be reduced avoiding potentially excessive power transmission and enabling data acquisition without cross talk to other channels (transmitter-receiver paths). This talk will present some of the work that we have done on how to use coded excitation to simultaneous transmit and receive signals on all channels of an array while also reducing the transmission power and maintaining a good SNR in the resulting signals.
