What is NOT a characteristic of tissue harmonics?

Created deeper in tissues
Linear in behavior
Not present as sound leaves the transducer
Created during transmission

The correct answer is: Linear in behavior

The correct answer identifies the characteristic that does not apply to tissue harmonics. Tissue harmonics are specifically generated during the propagation of ultrasound waves through the body, leading to non-linear behavior, unlike the linear behavior indicated in the answer choice. The generation of tissue harmonics occurs due to the non-linear propagation of sound waves in soft tissues, which means that higher frequency harmonic waves are produced as the primary sound waves travel through the medium. This non-linear behavior results in the creation of harmonics primarily at greater depths within tissues, as the sound waves become distorted and generate these additional frequencies. In contrast, the other options correctly describe properties of tissue harmonics: they are indeed created deeper within tissues, they are not present when sound leaves the transducer (as the harmonics develop only after penetrating tissue), and they result from interactions occurring during transmission rather than being a feature of the sound as it first exits the transducer. This understanding of harmonic generation is crucial for imaging techniques that rely on these principles to enhance the clarity and quality of ultrasound images.
