Here's why:
* High Frequency: Ultrasound waves have frequencies above the audible range of human hearing (typically above 20 kHz). This high frequency means they have shorter wavelengths.
* Shorter Wavelengths: Shorter wavelengths allow ultrasound waves to penetrate deeper into tissues compared to lower frequency sound waves.
* Less Absorption: Higher frequency waves are absorbed less by soft tissues, allowing them to travel further.
* Scattering: While ultrasound waves do scatter and reflect off of different tissue types, the high frequency allows for better resolution and imaging of internal structures.
In summary: The combination of high frequency, shorter wavelengths, and less absorption allows ultrasound waves to travel through the body and provide detailed images of internal organs and structures.
