Q

What are the 3 ways to display ultrasound image data?

A
  1. A mode (amplitude)
  2. B mode (brightness)
  3. M mode (motion)
2
Q

What is A-mode?

A

It is the amplitue of each reflector’s echo. It is placed on a graph across th depths of reflectors.

  • The Y axis: ampitide (strength of signal)
  • The X axis: depth of reflector.
3
Q

What us A mode used primarily for?

A

It is usually used for opthamology to accurately determine the depth of structures in the eye.

4
Q

What is B mode?

A

It is the bright or darker gray dots that display the strength of each echo along a vertical line representing the course of a soundwave.

5
Q

Describe the x,y,z axis on this picture.

A
  • Y axis: the depth of the reflector (origin of the echo)
  • X axis: each point on the transducer that sent a soundwave.
  • Z axis: the brightness of the dot, representing the strength of the echo.
6
Q

What is M mode?

A

Motion is displayed with wavy horizontal lines. A wavy horizontal line represents a reflector that is moving.

7
Q

What is M mode used for?

A

M mode is used to assess the motion of the heart.
