Abstract
An efficient compression strategy is indispensable for digital echocardiography. Previous work has suggested improved results utilizing wavelet transforms in the compression of 2D echocardiographic images. Set partitioning in hierarchical trees (SPIHT) was modified to compress echocardiographic scan-line data based on the wavelet packet transform. A compression ratio of at least 94:1 resulted in preserved image quality
