Unit Eleven: Ultrasound Modes

Practice vocabulary flashcards reviewing ultrasound display modes (A-mode, B-mode, and M-mode), their axes, and signal interpretations.

A-mode

Amplitude Mose display; an imaging format often used with Ophthalmology Practicies.

B-mode

Brightness mode display.

M-mode

Motion Mode display that uses one scan line to map the motion occurring in that line.

A-mode X-axis

The axis that shows the time of flight of the pulses or Depth.

A-mode Y-axis

The axis that shows the Amplitude of the reflectors.

B-mode X-axis

The line coming from the transducer.

B-mode Y-axis

The axis that represents the depth of the reflector.

2-axis (B-mode)

The axis on which Amplitude is graphed.

M-mode Sample Rate

A measurement equal to the PRF of the System.

Pattern of Squiggles

An M-mode display pattern indicating that anatomy is moving.

Horizontal Line (M-mode)

An M-mode display pattern that shows no motion.

Echo Near the Top

An echo indicating a shallow Structure.

Echo Towards the Bottom

An echo indicating a deep Structure.

M-mode X-axis

The axis that represents the time.

M-mode Y-axis

The axis that represents the Depth.
