Visualization can be defined as a methodology of
presenting ideas and information using pictures and
diagrams. The methodology of visual presentation has
drastically changed since the advent of computer
technology. Now with interactive graphics,
visualization techniques are no more confined to the
world of tables and simple graphs. In this thesis we
develop a Visual C++ system to visualize magnetic
field patterns of the heart patients to help
physicians in diagnosing any cardiac disorders. An
overview of medical imaging technologies forms the
beginning. We then present some of the paradigms in
the design of scientific visualization systems and we
present the advantages and challenges of
magnetocardiography and body-surface potential
mapping. The issues involved in the design of the
software are also addressed.
