Color m-mode imaging is a technique which uses pulsed Doppler interrogation along a single line of interrogation, similar to M-mode echocardiography. While M-mode echocardiography the intensity and location of the of a reflective spectral signal, in color m-mode Doppler, the Doppler velocity shift is recorded and then color encoded and superimposed on the M-mode image. This process results in high temporal resolution data on the direction and timing of flow events. Since this is a pulse Doppler technique, just as it was with color Doppler imaging velocity resolution is limited.
