A single transducer, such as a phased array transducer, is provided for various imaging situations with limited loss of resolution and/or penetration. The transducer includes different groups of elements, such as a center group with a fine pitch and outer groups with a larger pitch. The difference in pitch allows for an increased lateral extent of the array, and the fine pitched grouping allows for higher resolution and higher frequency imaging. The same transducer can be used for different imaging situations, such as for neonate imaging as well as imaging 140 pound adults. The difference in pitch also allows for the use of ultrasound imaging systems or beamformers with a limited number of channels even with the total lateral extent provided by the transducer array.
