摘要： 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 null 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. A transmit channel may connect to one electrode on an element, and the receive channel may connect to an opposite electrode on the element. The separate signal traces on each element allow the element to isolate the transmit and receive paths. A multi-dimensional array is provided for time division multiplex processing. A probe houses the multi-dimensional array and a multiplexer. The multi-dimensional array has a different distribution of elements along different dimensions, such as a 1.5 D array, a split bullet array, a multilayer linear array, or an I beam or nullbeam array formed from two or more linear arrays. The multiplexer enables operation of complex arrays for various ultrasound processes.
