Transducer array imaging system
Embodiments contemplate methods and devices for conducting ultrasound interrogation of a medium. An ultrasound echo wave may be received at a first transducer element of a transducer array in a handheld probe. The ultrasound echo wave may also be received at a second transducer element of the transducer array. The ultrasound echo wave may also be received at a third transducer element of the transducer array. The handheld probe may process into digital data the ultrasound echo wave received at the first transducer element and the ultrasound echo wave received at the second transducer element. The processing may preclude data representative of the ultrasound echo wave received at the third transducer element from being included in the digital data. The processing may include reducing the digital data and the reduced digital data may be transmitted to a location relatively remote from the handheld probe.
