  1. M-Mode Echocardiography John N. Hamaty D.O. SJHG

  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.
