Medical ultrasound imaging employs high-frequency acoustic waves to generate images of internal body structures.

C-mode is not a commonly used ultrasound imaging modality. A-mode, B-mode, and M-mode are more prevalent.

Ultrasound imaging does not involve ionizing radiation, making it safer for patients and healthcare professionals.

Bone density measurement is typically performed using X-ray or dual-energy X-ray absorptiometry (DXA), not ultrasound.

The Doppler effect is used in medical ultrasound imaging to measure the velocity of blood flow and detect abnormalities in blood flow patterns.

The Doppler spectrum is a graphical representation of the distribution of blood flow velocities within a sample volume.

Power Doppler is not a type of Doppler ultrasound imaging modality. Continuous-wave Doppler, pulsed-wave Doppler, and color Doppler are more common.

Color Doppler ultrasound imaging provides real-time visualization of blood flow patterns, while pulsed-wave Doppler imaging only provides information about blood flow velocity at a single point.

Intracranial pressure is typically measured using invasive techniques, not Doppler ultrasound imaging.

Absorption is the process by which ultrasound waves lose energy as they travel through a medium, resulting in a decrease in their intensity.

Viscosity, which is a measure of a fluid's resistance to flow, does not significantly affect the absorption of ultrasound waves.

Reflection is the process by which ultrasound waves bounce off a surface, changing their direction of propagation.

Temperature, within the normal physiological range, does not significantly affect the reflection of ultrasound waves from a surface.

Scattering is the process by which ultrasound waves are deflected from their original direction of propagation due to interactions with particles in the medium.

Temperature, within the normal physiological range, does not significantly affect the scattering of ultrasound waves by particles.
