← ScienceWhich outcome results from exceeding the sampling theorem constraint during pulsed wave doppler propagation?
A)Increased axial resolution occurs
B)Mirror image artifact appears✓
C)Elevated skin temperature develops
D)Reduced frame rate is recorded
💡 Explanation
A mirror image artifact arises because aliasing occurs when sampling rate is insufficient, which violates the Nyquist limit that causes under sampled signals to be interpreted as lower frequencies; therefore the reflected waves flip to create a mirrored copy, rather than accurate reconstruction.
