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.Slide6Slide7Slide8Slide9Slide10Slide11Slide12Slide13Slide14Slide15Slide16Slide17Slide18Slide19
