Which consequence ensues when impedance mismatches within phased array ultrasound?

A)Increased transducer element cross-talk.
B)Reduced signal-to-noise ratio occurs.
C)Elevated risk of electrical shorts.
D)Overall element structural degradation.

💡 Explanation

Signal loss occurs due to reflection at the interface because impedance mismatch invokes wave reflection at boundaries, therefore reducing SNR, rather than signal bleed via proximity because that is capacitive coupling.
