Row-column arrays have shown to be able to generate 3-D ultrafast ultrasoundimages with an order of magnitude less independent electronic channels thanclassic 2D matrix arrays. Unfortunately row-column array images suffer frommajor imaging artefacts due to the high side lobes. This paper proposes arow-column specific beamforming technique that exploits the incoherent natureof certain row column array artefacts. The geometric mean of the data from eachrow and column pair is taken prior to summation in beamforming, thusdrastically reducing incoherent imaging artefacts compared to traditionalcoherent compounding. The effectiveness of this technique was demonstrated insilico, and the results show an average fivefold reduction in side-lobe levels.Significantly improved contrast was demonstrated with Tissue-to-noise ratioincreasing from $\sim$10dB to $\sim$30dB and Tissue Contrast Ratio increasingfrom $\sim$21dB to $\sim$42dB when using the proposed new method compared toDelay and Sum. These new techniques allowed for high quality 3D imaging whilstmaintaining high frame rate potential.
