QUESTIONS LIST:

• soft tissue : ultrasonography is mainly used for imaging of _ structures of the abdomen, thorax and the msk system
• echoes : incoming _ are used to create an image
• amplitude : the _ of the returning echo sets the whiteness on the screen
• distance : time taken for the echo to return gives the _ between the transducer and structure (interface)
• top : closest structures are displayed at the _ of the screen

• scattered : when sound strikes many small/uneven boundaries/interfaces & it is refracted/reflected in multiple directions, this is called a _ beam
