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.

Abstract: Transducer arrays and methods of manufacturing the transducer arrays are provided. A multi-dimensional transducer array is provided where the element-to-element spacing or pitch along one dimension is less than the element spacing or pitch along a second dimension. For example, the element pitch along an azimuth dimension is ½ of the element pitch along an elevation 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. Separate dicing allows for individual testing of modules prior to assembly as a transducer array. Elements of a transducer array are used for isolating a transmit channel from a receive channel. Rather than a sheet of electrode acting as a ground plane common to a plurality of elements, separate signal lines or traces are provided individually for each element on opposite sides of each element.

Abstract: An ultrasound transducer array (250) in which the piezoelectric layer (256) and the matching layer(s) (258) have different sub-dicing. In one embodiment, the piezoelectric layer (256) is diced only once and the matching layer(s) (258) is diced more than once. A resulting transducer shows improved bandwidth, crosstalk and noise performance.
