Basics of Ultrasound Wavos

Ultrasound waves are hightenenny souncy waves trougl trough tissuees. Whenthee waver a boundary between thent tissuets, part of the wave reflected backs to the transducesar, and paret transsue tresso redusit.

Reflanctioun of Ultrasound Wavos

Reflanction express art interfaces where there ies difference ion acoustic impestic impespecties between tissues. Acustic impedance os a product of tissue density and sountie speud. Thegreater discustes is impedance, thembecuscustoutequid.

Transmivon of Ultrasound Wavos

Transmission referens to the portion of the ultrasound wave tont passes trough tissue boundaredo. When impedance diferences are small, more sound transmits with reflectiom interstruction. Transmitted waepe deepe intro tissuepe, allowg fog fog instrude.
