What Does Ultrasound Gel Do?

The video explains how ultrasound technology is used in medical imaging. It describes the process of generating ultrasound waves, their properties, and how they create images of the body's internal structures. The role of ultrasound gel in improving wave transmission is highlighted, along with the concept of acoustic impedance. The video concludes with how computers use reflected waves to generate detailed images.

What is the primary function of an ultrasound transducer in medical imaging?

• To measure blood pressure

• To emit light waves

• To create and receive ultrasound waves

• To monitor heart rate

Why are ultrasound waves considered safe for medical imaging?

• They are just sound waves

• They do not penetrate the skin

• They are visible to the human eye

• They are low-frequency waves

What characteristic of ultrasound waves makes them suitable for creating detailed images?

• Their ability to be heard by humans

• Their ability to spread out widely

• Their low energy levels

• Their high frequency and short wavelength

How does ultrasound gel aid in the imaging process?

• By providing a visual contrast

• By amplifying sound waves

• By reducing the acoustic impedance difference

• By cooling the skin

What role does a computer play in ultrasound imaging?

• It processes reflected waves to create images

• It measures the temperature of the body

• It amplifies the ultrasound waves

• It generates sound waves
