Array architecture and interconnection for transducers

An ultrasound system comprising:

• an ultrasound device with a transducer having:
• a backing block;
• and
• stack configurations aligned on the backing block, wherein the stack configurations each comprise:
• a piezoelectric layer, wherein a gap is formed in elevation in-between each piezoelectric layer and each adjacently aligned piezoelectric layer, wherein each stack configuration has a height in elevation, a width perpendicular to the height in azimuth, and a stack-up thicknesses-configuration, wherein the stack-up thicknesses-configuration is perpendicular to the height and perpendicular to the width, wherein the widths of the stack configurations are equivalent to each other;
• and
• one or more matching layers coupled to the lens and bonded to each piezoelectric layer, wherein a conductive surface of a matching layer of the one or more matching layers is coupled to a top surface of each piezoelectric layer,
• wherein the backing block comprises three or more block sections and each stack configuration of the stack configurations aligned on the backing block is aligned with one or more of the three or more block sections forming at least two outer rows and a center row, wherein the center row generates a first frequency signal and the at least two outer rows generate a second frequency signal, and wherein a frequency of the first frequency signal is not equivalent to a frequency of the second frequency signal.
