<P>In medical ultrasound imaging, the focused echo signal is decimated with a finite impulse response filter by a rational factor <I>M</I>/<I>L</I>, the frequency response of which dynamically changes over time. Presented is, an efficient structure for dynamic decimation by a programmable rational factor that use a fixed number of polyphase multiplier-accumulators (MACs) regardless of the values of <I>M</I> and <I>L</I>. The proposed structure uses the minimum number of MAC units operating at the input data rate to minimise both power consumption and hardware complexity.</P>
