Abstract: Finger probe for use in ultrasonic imaging includes a housing and a matrix array arranged within the housing to produce ultrasound beams and which includes a plurality of independently-addressable transducer elements. A finger clip is coupled to the housing and arranged to accommodate an operator's finger. A control unit is coupled to the transducer elements to provide planar and volumetric scanning capabilities. A system and method for ultrasonically interrogating a patient's body part and for producing ultrasound images based on the interrogation using a finger-mounted ultrasound probe are also disclosed.
