Abstract

An efficient compression strategy is indispensable for digital echocardiography, which is very important for clinical practice of cardiology. In this study, we investigated a new compression strategy applied to pre-scan-converted polar format echocardiographic video instead of scan-converted raster format video. A lossy compression strategy, using modified SPIHT based on wavelet packet transform, is used to compress tissue data; while a lossless compression strategy based on integer wavelet transform, is used to compress Doppler data. The proposed algorithm can achieve very high compression ratio while retaining excellent image quality. Furthermore, the modified SPIHT surpasses the original SPIHT for the compression of tissue data.
