Abstract

An ultrasound system and method is described in which a probe is used in conjunction with a main unit. The probe contains at least two different transducer or transducer array types to provide an operator with a selection of transducer types for use without having to change to a different probe. Transducer types may include wide-band and narrow band transducers or transducer arrays within a single probe, and may be selected for use by a selector switch on the probe. Data collected by the probe during operation may be transmitted wirelessly back to a main unit through the use of a wireless antenna incorporated into the probe. In addition, one of the transducers at either end of the probe may be replaced by an adjunct equipment type such as a stethoscope.
