The potential of interactive multimedia and Internet technologies is i
nvestigated with respect to the implementation of a distance learning
system in medical imaging. The system is built according to a client-s
erver architecture, based on the Internet infrastructure, composed of
server nodes conceptually modelled as World Wide Web (WWW) sites. Site
s are implemented by integration and customization of available compon
ents. The system evolves around network-delivered interactive multimed
ia courses and network-based tutoring, which constitute its main learn
ing features. This potential has been demonstrated by means of an impl
emented system, validated with digital image processing content, speci
fically image enhancement. Image enhancement methods are theoretically
described and applied on mammograms. Emphasis is given in the interac
tive presentation of the effects of algorithm parameters on images. Th
e system end-user access depends on available bandwidth, so high speed
access can be achieved via LAN or local ISDN connections.
