Description Dramatic changes in the information and communication technologies have brought about an impact in the healthcare community. Imaging procedures
with direct digital radiography, virtual endoscopy, spiral CT and interventional MR identify a few of the manifestations of this increasing
development. To handle the complexity of this new technology, CAR'99, held in Paris, brought together professionals who focused
on this intellectual challenge. Intelligent handling of existing and future informatic tools in healthcare relies on the interdisciplinary
and international cooperation promoted by the CARS congress.
CAR'99 is a compilation of 190 lectures and 100 poster presentations
focused on the medical image in diagnosis, therapy and communication. One challenge of the congress is to handle the complexities involved
in the integration of Computer Assisted Medicine (CAM) which includes the prevention, diagnosis, therapy and homecare. The congress also
discussed the dangers and conflicts involved in the dependence on digital technology for diagnosis and decision-making.
Car '99
will prove to be essential to the healthcare provider.
Optimal care can only be achieved through the complimentary talents of the healthcare
workers and the digital system. Physicians will have to be prepared to meet the challenges of a new revolution...learning how to make
the best use of technology, in the interest of their patients and of their professional survival.
Audience
Physicians from Clinical Research, Practising specialists in diagnostic radiology, nuclear medicine, radiation oncology, orthopaedics
and surgery, radiological technicians, medical computer specialists, dentistry and oral surgery
