WebFor example, the conventional design of diffusion encoding gradients for spin echo, echo planar imaging (EPI), as described by Stejskal and Tanner 1, is not always time-optimal due to the symmetric diffusion encoding gradient design and the typically unequal duration available for diffusion encoding on either side of the RF refocusing pulse (Fig. 3B). WebThe side lobe artifact is caused by echo reflections from the side lobe beam of the transducer. Imaging Modes. The reflected echo can be displayed in different modes: A-mode: Amplitude modulation, display of the echo in a diagram, the x-axis represents the depth and the y-axis the echo intensity.
