← ScienceWhich outcome results when a high-intensity focused ultrasound (HIFU) transducer malfunctions?
A)Localized tissue temperature rises excessively✓
B)Acoustic cavitation becomes globally unstable
C)Harmonic wave propagation becomes isotropic
D)Electrical impedance matching fails gracefully
💡 Explanation
Excessive localized temperature increase arises because of faulty piezoelectric element impedance during acoustic wave propagation; this causes uncontrolled energy deposition via tissue absorption of ultrasonic energy rather than targeted ablation alone, therefore a dangerously localized overheat results.
