    Study Notes

    Ultrasound Technology

    • Ultrasound technology uses high-frequency inaudible sound waves, above 20 km2, for echolocation and navigation.
    • Echolocation is a method of navigating using sound waves rather than sight.

    Components of Ultrasound Equipment

    • Trackditder: produces sound waves
    • Console: controls the system
    • CPU: processes the data
    • Probe: transducer that produces and receives ultrasound pulses

    Principles of Ultrasound

    • Ionoffoce: more reflection occurs with a larger difference in acoustic impedance between two media
    • Gel is used as a medium between the probe and the skin to reduce refraction and increase reflection
    • Sound waves can be absorbed by certain materials, such as bone and air

    Applications of Ultrasound

    • Early pregnancy detection and monitoring of the uterus
    • Real-time imaging of internal organs and structures
    • Doppler ultrasound: measures blood flow and velocity

    Advantages of Ultrasound

    • No radiation exposure
    • Non-invasive and comfortable for patients
    • Wide availability and accessibility
    • High-resolution imaging with fine details
    • Excellent for guiding interventional procedures
