The operations of digitization, transmission and storage medical data, particularly images, require increasingly effective encoding methods not only in terms compression ratio flow information but also visual quality. At first, there was DCT (discrete cosine transform) then DWT wavelet their associated standards coding image compression. 2nd-generation wavelets seeks to be positioned confronted by the video currently used. It is this context that we suggest a method combining bandelets SPIHT (set partitioning hierarchical trees) algorithm. There are two main reasons for our approach: first lies nature bandelet transform take advantage capturing geometrical complexity structure. second reason suitability coefficients encoder. Quality measurements indicate some cases (for low bit rates) performance proposed competes with well-established ones (H.264 or MPEG4 AVC H.265 HEVC) opens up new application prospects field imaging.
