New advanced e-health applications are required to support the effective processing of diagnostic and therapeutic healthcare protocols in modern societies. Looking at the work flow handled by the consulted medical staff in the first level of a medical treatment chain such as family doctors, an effective treatment usually requires the processing of pre-recorded medical images of a patient during the first diagnostic phase. We consider the development of a Web server architecture that offers the transport of medical images by an Android application and illustrate its design by a realized PACS prototype. The effective data transport of medical images is realized by a multipath-QUIC protocol which is integrated into a DICOM proxy server. Its further development can integrate other fog computing systems which support additional interconnected e-health applications employed by a consortium of users in a medical treatment process.
