Abstract:
Paradigm shifts in technology are needed for next-generation ultrasound imaging. We introduce novel electrostrictive row-column array technology that promises improved 3D image quality and ultrafast imaging speeds. Moreover, these advances will lead to arrays of unprecedented size and novel form-factors such as endoscopic probes and wearable band-aids that will mitigate operator dependence and lead to longitudinal imaging opportunities. Our technology enables readout from every element of the 2D array using only row and column addressing, and is well-suited to volumetric photoacoustic imaging using pulsed laser excitation to image optical properties of tissues. Novel agents and genetically-encoded reporters will be introduced. Applications to brain imaging, cardiovascular medicine, small animal imaging will be discussed. Furthermore, a new non-contact all optical form of photoacoustic imaging will be discussed with applications to virtual histology of tissues.
