Key ideas in Seeing with Sound: Ultrasound Basics
- Ultrasound updates continuously based on returning sound waves
- The probe alternates between sending sound and listening for it
- Movement results in an immediate change on the display
- Sound must physically travel to a structure and back to be recorded
- The image represents a live 'slice' of the body
- The time it takes for the echo to return determines the depth
- The cycle of sound transmission and reception
- Air is a total barrier to ultrasound waves
- Gel eliminates the air gap between the probe and the skin
- Ultrasound is a dynamic map of sound reflections
- The physical notch on the probe corresponds to a specific side of the monitor
- The role of gel in sound transmission
- Aligning the physical probe marker with the screen indicator
- Ultrasound captures functional movement like blood flow or muscle contraction
- Live feedback allows for 'guiding' procedures as they happen
- Static structures like bone density are better suited for other imaging types
