Ultrasound signal

The term "ultrasound signal" refers to sound waves with frequencies above 20,000 Hz, which is above the human auditory range. In medical contexts, ultrasound signals are emitted by specialized transducers and used to generate real-time images (sonograms) of soft tissue structures inside the body for diagnostic purposes. The signal is not a biological molecule or a cellular target, but a physical wave manipulated by equipment for medical imaging and occasionally for therapeutic interventions. The signal is generated by piezoelectric crystals in the transducer, travels through body tissues, and returns as echoes to help create images[1][2][4][5][6]. There is no receptor, enzyme, or target protein corresponding to "ultrasound signal"; it is not a druggable target but a technological tool. This entry is considered "incorrect" as a therapeutic or pharmacological target, since it does not correspond to a molecule, receptor, or any structure appropriate for targeted drug action in biomedical research or clinical development contexts.
