A general challenge in 3D volumetric imaging is the large channel count. One solution uses integrated microbeamformers. The reconstruction of the entire volume from these micro-beamformed datasets can be performed in many ways. In this paper we propose two 3D multiline beamforming techniques, suitable for producing volumes at high frame rate and compare the image qualities to a fully-sampled matrix...
This paper presents a 9-channel low-power receiver ASIC dedicated to a matrix piezoelectric ultrasound transducer for 3D Trans-Esophageal Echocardiography (TEE). It consists of 9 low-noise amplifiers (LNAs), 9 time-gain-compensation (TGC) amplifiers and a 9∶1 micro-beamformer. A prototype ASIC has been implemented in 0.35 µm CMOS technology, with a core area of 0.98 mm × 1.7 mm. It is operated at...
