Ultrafast 3-D Transcutaneous Super Resolution Ultrasound Using Row-Column Array.

Project – Ultrafast 3-D Transcutaneous Super Resolution Ultrasound Using Row-Column Array Specific Coherence-Based Beamforming and Rolling Acoustic Sub-aperture Processing

We have developed a novel reconstruction algorithm called Row-Column specific Frame Multiply and Sum. In this algorithm the incoherence of orthogonal plane wave transmissions using the row-column array is exploited improve the quality of 3D ultrasound images. This algorithm has been combined with a Acoustic-Sub aperture processing creating a rolling reconstruction technique which increases the effective frame-rate whilst also decreasing the signal-to-noise ratio. By using these reconstruction techniques within an ultrasound localisation microscopy pipeline we have managed to achieve transcutaneous super resolution image using a row-column array for the first time. These techniques have been applied pre-clinically and are currently being translated into a clinical setting.
