3. What is Med-LIFE?
Med-LIFE is an application currently under development to use computer processing techniques to reduce medical personnel workload
GUI designed with QT
Image Processing with C (and VTK library)
JN 7/26/2019

4. What is Med-LIFE? Consists of Three Processes (LIFE):
Learning of image attributes by the computer using SFAM
Image Fusion of many image modalities into one color image
Exploration of learning and fusion results
JN 7/26/2019

5. What is image fusion?
Allows the combination of multiple image modalities into one colored image with no information loss
Reduces workload by eliminating the number of images a radiologist must analyze
Images used from “The Whole Brain Atlas”

6. What is image fusion?
Technique similar to primate vision

8. Image Fusion Example

9. How do I teach the computer?
SFAM – Simplified Fuzzy ARTMAP
SFAM is a computer-based system capable of online, incremental learning
Two “vectors” are sent to this system for learning:
Input feature vector tells what data is available from which to learn
Supervisory signal tells whether that vector is an example or counterexample

10. How do I teach the computer?
Left-click to define examples (green)
Right-click to define counterexamples (red)

11. How do I teach the computer?
Supervisory signal from red/green marks
Feature vector from slice pixel values for original, single, and double opponent images

14. How can I view results? Display a plethora of information
Skull generated for patient from PD modality for contextual slice navigation
Explore tab provides several functions:
Original images
Fusion results imbedded within 3D, patient-generated skull
Learning results

16. Conclusion
Med-LIFE offers reduced workload to physicians who scan multiple images
Image processing and fusion reduces the number of images to be analyzed
Learning system allows the computer to perform prescreening or background analysis
Exploration allows immersion within the data for operational planning
