Study Notes
Ultrasound Imaging Basics
- Infrasound refers to sound waves with frequencies below 20Hz.
Transducer Function
- The transducer in ultrasound imaging converts electrical energy into sound waves and vice versa.
Quartz Crystal Properties
- Quartz crystals possess a unique physical characteristic called piezoelectricity, which allows them to generate an electric charge when subjected to mechanical stress.
Audible Sound Range
- The speed range for audible sound is between 20 Hz and 20,000 Hz.
Ultrasound Imaging Definition
- Ultrasound imaging, also known as sonography, is a medical imaging technique that uses high-frequency sound waves and their echoes to produce images of internal organs and structures.
