would be effective enough
to help radiologists?

9. ANN
Ability to classify and recognize patterns
ANNs have been used to interpret:
• plain radiographs
• ultrasound
• CT
• MRI
• Radioisotope scans
In radiology both are possible as inputs:
• human observations
• direct digitized images

12. Fuzzy
expert
systems
The science of
reasoning, thinking and inference
that recognizes and uses
the real world phenomenon
that everything is a matter of degree
They have been applied to characterize
• ultrasound images of the breast
• ultrasound and CT scan images of liver lesions
• MRI images of brain tumors

13. Evolutionary
computation
They have been used in:
• Computerized analysis of mammographic
micro-calcification,
• MRI segmentation of brain tumors to measure
the efficacy of treatment strategies
• Analyzing computerized 2-D images to
diagnose malignant melanomas
imitates the mechanism of
natural selection and
survival of the fittest
in solving real-world problems
Most widely used form for medical applications are ‘Genetic Algorithms’

14. Hybrid
intelligent
systems
The popular ones are:
•ANNs for designing fuzzy systems
•Fuzzy systems for designing ANNs
•Genetic Algorithms for
automatically training and
generating neural network
architectures
Analysis of microcalcification on
digital mammograms

15. However, in spite of earlier optimism, medical AI
technology has not been embraced with enthusiasm.
One reason for this is the attitude of the clinicians
towards technology being used in the decision-making
process.
Paradoxically, there is no doubt in accepting the
• Biochemical results generated from an auto-analyser
• Images produced by MRI
