An ultrasound imaging transducer receives echo data from a matrix of elements distributed in two or more dimensions. Received echo data is delayed using an analog delay circuit consisting of an array of signal storage capacitors addressed by input and output switches addressed by input and output counters. The output of the ARAM is digitized by an analog to digital converter (ADC). Digital data is processed and streamed to a base system for further processing to form and display an image. The input counter address update phase is programable in quanta less than or equal to one half the input counter address update period. The output counter address update phase is held at a fixed phase relationship to the ADC sampling clock. The signal delay through the ARAM is controlled by the summation of two or more controls.

While 3D ultrasound imaging is becoming a powerful tool in medical field, the main drawback is the difficulty to image large 3D volume, mainly related to the dimensions of the 2D array of transducers. In order to not lose in spatial resolution, it is necessary to use an array of transducers, wherein the size of the transducers does not exceed the wavelength of the ultrasound wave. Such requirement leads to dimensions of array for imaging large 3D volume which are not reachable or at too high cost with the current technology. The present disclosure overcomes the above technology limitation by using greater transducers, and where each transducer has a reception surface with a curved shape or is fitted with an acoustic lens. Such configuration of transducers leads to 2D array of transducers suitable for imaging large 3D volume, as a brain or a heart, with high resolution and high sensitivity.
