Abstract：

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.
