<p><P>PROBLEM TO BE SOLVED: To provide a system and a method for signal filter processing. <P>SOLUTION: A signal filter (306) includes a linear regression filter component (308) and a finite impulse response filter component (310). A received signal is filter-processed by the linear regression filter component (308) at first and then filter processed by the finite impulse response filter component (310). In one embodiment of this invention, a system and a method for filter processing for a low frequency tissue deflection signal reflected by a vascular wall to carry body fluid (e.g. blood), especially a low frequency signal reflected by a body region during medical imaging are provided. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
