Abstract :
1.5D transducer arrays represent a promising improvement in ultrasonic B-mode imaging. The reduction of the slice thickness and the correction of phase aberration are potential applications of 1.5D arrays, while keeping the number of electronic channels on ultrasound beamformers between 64 and 256. The authors present the design and manufacturing, using a high density interconnection process, of a 1.5D curved linear array with 128×4 independent elements, allowing dynamic focusing in the elevation plane
