M-Mode Echo

Used in combination with 2-dimentional

Rapid sampling of a region results in placing sequential parallel data lines so close together that individual points of brightness appear as continuous horizontal lines.

90 degrees to sample- “ice pick”Slide4

M-Mode Echo

This narrow field allows fewer pulses with a higher frame rate and therefore better temporal resolution

Factors that shorten the time required to make a frame will act to improve temporal resolution.Slide5

Improving Temporal Resolution

Minimize depth of view

Use single focus

Narrow sector

Minimize line density

As temporal resolution improves, image quality may degrade.Slide6
