Transcript text: What is used as a coupling agent when the transducer makes contact with the body?

Solution

Solution Steps

Step 1: Understanding the Role of a Coupling Agent

A coupling agent is used to facilitate the transmission of ultrasound waves from the transducer into the body. It helps to eliminate air gaps between the transducer and the skin, which can cause reflection and scattering of the ultrasound waves, reducing the quality of the image.

Step 2: Evaluating the Options

A) Water: While water can be used as a coupling medium, it is not commonly used in clinical settings due to its tendency to evaporate and run off the skin.
B) Baby oil: This is not typically used as a coupling agent because it can be messy and does not provide the optimal acoustic properties needed for ultrasound imaging.
C) Aqueous gel: This is the most commonly used coupling agent in ultrasound procedures. It is specifically designed to provide good acoustic transmission and to stay in place during the procedure.
D) Electrode paste: This is used for attaching electrodes to the skin, not for ultrasound imaging.

Final Answer

The correct answer is \(\boxed{\text{C) Aqueous gel}}\).
