Summary
Objectives: Medical image computing has become one of the most challenging fields in medical
informatics. In image-based diagnostics of the future software assistance will become
more and more important, and image analysis systems integrating advanced image computing
methods are needed to extract quantitative image parameters to characterize the state
and changes of image structures of interest (e.g. tumors, organs, vessels, bones etc.)
in a reproducible and objective way. Furthermore, in the field of software-assisted
and navigated surgery medical image computing methods play a key role and have opened
up new perspectives for patient treatment. However, further developments are needed
to increase the grade of automation, accuracy, reproducibility and robustness. Moreover,
the systems developed have to be integrated into the clinical workflow.
Methods: For the development of advanced image computing systems methods of different scientific
fields have to be adapted and used in combination. The principal methodologies in
medical image computing are the following: image segmentation, image registration,
image analysis for quantification and computer assisted image interpretation, modeling
and simulation as well as visualization and virtual reality. Especially, model-based
image computing techniques open up new perspectives for prediction of organ changes
and risk analysis of patients and will gain importance in diagnostic and therapy of
the future.
Results: From a methodical point of view the authors identify the following future trends
and perspectives in medical image computing: development of optimized application-specific
systems and integration into the clinical workflow, enhanced computational models
for image analysis and virtual reality training systems, integration of different
image computing methods, further integration of multimodal image data and biosignals
and advanced methods for 4D medical image computing.
Conclusions: The development of image analysis systems for diagnostic support or operation planning
is a complex interdisciplinary process. Image computing methods enable new insights
into the patient’s image data and have the future potential to improve medical diagnostics
and patient treatment.
