Abstract

Acquisitions of 3-D (x,y,t) and 4-D (x,y,z,t) medical image sequences become usual, especially in the case of dynamic studies performed with modalities such as MRI, fast x-ray CT, or PET. It results in a significant increase of data volume and, consequently, the necessity, which is emphasized by the development of PACS, to reduce storage space and transmission bandwidth. A multidimensional image sequence coding method based on a multiple decorrelation scheme is presented. In a first step, an orthogonal transform, such as factor analysis (similar to discrete Karhunen-Loeve transform), is applied to decorrelate initial data according to temporal dimension. In a second step, the resulting orthogonal image sequences are decorrelated using a 3-D discrete cosine transform (DCT). The resulting dataset is quantized using an optimal Max quantizer. This irreversible coding is applied to MRI, fast x-ray CT, and PET image sequences. Its evaluation is performed using quantitative and observer independent methods taking into account the specificity of medical dynamic data.
