Abstract
A multi-dimensional transducer array has pitch along one dimension less than the pitch along a second dimension. The multi-dimensional transducer array with the same or different pitch is manufactured from a plurality of modules. Each of the modules are separately diced and then aligned and combined. Elements of a transducer array are used for isolating a transmit channel from a receive channel. Separate signal lines or traces are provided individually for each element on opposite sides of each element. A transmit channel may connect to one electrode on an element, and the receive channel may connect to an opposite electrode on the element. A multi-dimensional array is provided for time division multiplex processing. A probe houses the multi-dimensional array and a multiplexer.
