2. 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”
3. 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.
4. Improving Temporal Resolution
• Minimize depth of view
• Use single focus
• Narrow sector
• Minimize line density
• As temporal resolution improves, image
quality may degrade.
