Published paper “CASANDRA: A prototype implementation of a system of network progressive transmission of medical digital images” (J. Villanueva-Oller, R.J. Villanueva, S. Díez), in the Computer Methods and Programs in Biomedicine nº 85, ISSN 0169-2607, pp. 152-164, (year 2007). Ed. Elsevier Ireland.

In this paper, a prototype for progressive transmission of medical digital 2D images through the network, called CASANDRA, is presented. The prototype consists of the server part and the client part. In the server part, the images are acquired, stored, computed their wavelet transform and the wavelet coefficients stored, then transmitted progressively, when required, via TCP to the client. In the client part, with the inverse wavelet ransform, the received wavelet coefficients are used to build successive improved reconstructions of the image. This prototype has been implemented and is being tested in the Radiotherapy Service of the Valencia University Hospital (Valencia, Spain).
