Abstract

A method and a device for imaging an object using ultrasound. Transducer elements of a two-dimensional array are interconnected to form sub-arrays. The transducer elements of each sub-array are driven in the transmit mode with the same time delay and read out jointly in the receive mode. In this manner, the number of required time delays is reduced, and parasitic capacitances on the signal lines are diminished.
