Patent ID: 8286488

Claim:
A measurement system, comprising: a measurement probe including a delay block having a longitudinal axis and a plurality of transducer elements acoustically coupled to the delay in a manner forming an active group, the active group including a transmitter side for generating an ultrasound beam and a receiver side for receiving an echo signal, the receiver side in a spaced relationship with the transmitter side, the spaced relationship forming a gap about the longitudinal axis, the gap including a cross-talk barrier disposed in a manner acoustically separating the transmitter side and the receiver side; and a test instrument coupled to the measurement probe, the test instrument including an interface controlling at least one transducer element in the active group in a manner causing a first parameter of the ultrasound beam, wherein the receiver side includes at least one transducer element responsive to the echo that corresponds to the ultrasound beam, and wherein the measurement probe includes a first active group and a second active group that has a number of transducer elements that is different from the first active group.
