Abstract-The efficient transmission of large resolution images and, in particular, the interactive transmission of images in a client-server scenario, is an important aspect for many applications. Among the current image compression standards, JPEG2000 excels for its interactive transmission capabilities. In general, three mechanisms are employed to optimize the transmission of images when using the JPEG2000 Interactive Protocol (JPIP): 1) packet re-sequencing at the server; 2) prefetching at the client; and 3) proxy servers along the network infrastructure. To avoid the congestion of the network, prefetching mechanisms are not commonly employed when many clients within a local area network (LAN) browse images from a remote server. Aimed to maximize the responsiveness of all the clients within a LAN, this work proposes the use of prefetching strategies at the proxy server -rather than at the clients. The main insight behind the proposed prefetching strategies is a user-navigation model and a semantic map that predict the future requests of the clients. Experimental results indicate that the introduction of these strategies into a JPIP proxy server enhances the browsing experience of the end-users notably.

Abstract-Access to all relevant information at the diagnostic decision moment improves the quality of care. With the deployment of the Electronic Health Record (EHR), information resides in different distributed systems. When conducting a diagnosis based on medical images for example, the physician needs to compare old images with current ones, while old images may reside in a different system: they need to import images for visualization which leads to a problem related to persistency management and information consistency. Since image streaming promises a solution for avoiding image import, we describe here how JPEG 2000 Interactive Protocol (JPIP) can be used to enable streaming of medical images directly from EHR connected image archives to visualization workstations. Moreover, we describe JPIP implementations in order to visualize a large image and present measurements of bandwidth efficiency improvements.

The electronic health record (EHR) is expected to improve the quality of care by enabling access to relevant information at the diagnostic decision moment. During deployment efforts for including images in the EHR, a main challenge has come up from the need to compare old images with current ones. When old images reside in a different system, they need to be imported for visualization which leads to a problem related to persistency management and information consistency. A solution consisting in avoiding image import is achievable with image streaming. In this paper we present, evaluate, and discuss two medical-specific streaming use cases: displaying a large image such as a digital mammography image and displaying a large set of relatively small images such as a large CT series.
