Topic explanation

Standard explanation

Doppler ultrasound uses the Doppler effect to measure motion, particularly the movement of blood.

Key points

• Δf = 2f₀v cosθ/c
• Formula / Key Relation: When ultrasound reflects from moving blood cells, the reflected frequency can differ from the transm
• Frequency shift gives information about blood velocity.
• Doppler ultrasound uses the Doppler effect to measure motion, particularly the movement of blood.
