Final answer:
Ultrasound at lower intensities is used for imaging, such as fetal monitoring and diagnosis, while higher intensities can destroy tumors. Doppler ultrasound measures movement and velocity through the Doppler shift, crucial for monitoring blood flow and heart activity.
Step-by-step explanation:
Ultrasound imaging is capable of both observing a fetus in the womb and destroying cancerous tumors because of its flexibility in usage at different intensities. When used at lower intensities, ultrasound is a non-invasive tool that can generate real-time images without causing any damage, making it ideal for medical imaging such as monitoring fetal development or diagnosing conditions like gallbladder disease. Higher intensities of ultrasound can be used therapeutically to pulverize and destroy targeted tissues, such as ovarian cancer tumors.
Doppler ultrasound is another crucial application of this technology in medical diagnostics. It detects motion and determines velocity by analyzing the Doppler shift of an echo produced by moving tissues or blood flow. This feature is particularly important for monitoring fetal heartbeat, assessing blood velocity, and detecting occlusions in blood vessels.
