Across
- 2. Waves propagate by particle motion that is perpendicular to the wave propagation direction
- 3. Waves propagate by particle compression and rarefaction that results in particle motion that is along or in the same direction as the wave propagation direction
- 8. The principle of converting energy by applying pressure to a crystal
- 10. A structure or tissue that reflects a high amount of ultrasound waves, appearing brighter on the ultrasound screen compared to surrounding tissues
- 11. An area of tissue that appears darker than the surrounding structures on an ultrasound image because it reflects fewer sound waves, or is less echogenic
Down
- 1. Wave that will work in medium or vacuum
- 4. The ability of tissue to return a signal when exposed to an ultrasound beam
- 5. Cylindrical transfer of energy
- 6. Wave that needs a medium to propagate
- 7. Does not produce returning sound waves
- 9. Mechanical energy that is transmitted through a medium by forces acting on molecules
