What are the three modes of display?

Amplitude Mode (A-mode)

Brightness Mode (B-mode)

Motion Mode (M-mode)

Which mode is being described?

Looks like a series of upward spikes, a single jagged line, or a big city skyline.

A-mode

Which mode is being described?

The x-axis represents the reflector depth and the y-axis represents the amplitude of the reflected signal.

A-mode

Which mode is being described?

Strong echos create tall spikes and weak reflections create short spikes.

A-mode

Which mode is being described?

Used extensively in ophthalmology

A-mode

Which mode is being described?

Appears as a line of dots of varying brightness.

B-mode

Which mode is being described?

It was the first form of gray scale imaging and is the basis for all other types of gray scale imaging.

B-mode

Which mode is being described?

The x-axis represents the reflector depth, the amplitude of the reflection is represented by the brightness of the dot and is sent into the z-axis of an oscilloscope.

B-mode

Which mode is being described?

The brightness of the dot indicates the strength (amplitude) of the reflection.

B-mode

Which mode is being described?

Weaker reflections appear as darker gray dots and stronger reflections appear as brighter white dots.

B-mode

Which mode is being described?

Appears as a group of horizontal wavy lines.

M-mode

Which mode is being described?

Used in real time imaging.

M-mode

Which mode is being described?

The x-axis represents time and the y-axis represents reflector depth.

M-mode

Which mode is being described?

The only mode that provides information about a reflector's changing location with respect to time.

M-mode

Which mode is being described?

Primarily used to assess the motion of cardiac walls and structures, such as fetal heartbeat.

M-mode
