Omnidirectional M-mode echocardiography(OME) can detect dynamic information from sequential echocardiography images. Temporal motion velocity and acceleration of a part of the cardiac structure contains the information about the composition of forces related to a heart. In this paper we present methods for detection of temporal motion velocity and acceleration of OME. Gray-time waveforms are rebuilt from sequential images of OME on arbitrary direction lines to track moving structure. Using one-order and two-order differential of the discrete function, temporal velocity and acceleration of one part of the cardiac structure are obtained. The measurement of temporal velocity and acceleration has been applied to 30 clinical cases. Results indicate that along the same direction lines, the velocities measured are not significantly different compared with original B-scan echocardiography.
