Knowledge-Guided Processing Of Magnetic Resonance Images Of The Brain, Matthew C. Clark
Knowledge-Guided Processing Of Magnetic Resonance Images Of The Brain, Matthew C. Clark
USF Tampa Graduate Theses and Dissertations
This dissertation presents a knowledge-guided expert system that is capable of applying routinesfor multispectral analysis, (un)supervised clustering, and basic image processing to automatically detect and segment brain tissue abnormalities, and then label glioblastoma-multiforme brain tumors in magnetic resonance volumes of the human brain. The magnetic resonance images used here consist of three feature images (T1-weighted, proton density, T2-weighted) and the system is designed to be independent of a particular scanning protocol. Separate, but contiguous 2D slices in the transaxial plane form a brain volume. This allows complete tumor volumes to be measured and if repeat scans are taken over time, …
