Gel coupling solution is widely used in medical imaging, particularly in ultrasound procedures. It acts as a medium to enhance the transmission of sound waves between the transducer and the skin, ensuring clearer and more accurate imaging. The solution eliminates air gaps that can interfere with the ultrasound waves, improving the quality of diagnostic results. It is also commonly applied in therapeutic ultrasound treatments to facilitate the delivery of ultrasound energy to targeted tissues. Additionally, its hypoallergenic and non-greasy properties make it safe for use on various skin types, ensuring patient comfort during procedures.
