Interactive Visual Analysis of Medical Perfusion Data
Blood flow is essential for the healthy function of organs such
as the heart, the kidneys, or the brain. To assess whether the
flood flow through particular parts of organ tissue is normal,
medical perfusion imaging is performed (amongst other diagnosis
procedures). With the help of a contrast agent and repeated
scans of MRI, the characteristics of flood flow are analyzed,
especially also in areas of the peripheral arteries (e.g., in
muscles or in the gray matter of the brain). In a collaborative
effort (Magdeburg, Wien, Bergen), we characterize the temporal
behavior of the measurements of the data by multiple expressive
shape parameters (such as time-to-peak, slope, etc.) and employ
modern visualization technology (interactive visual analysis) to
extract valuable information from this multi-variate dataset.
This way, we are able to efficiently and effectively analyze
infarction cores in the brain, infarcted regions in the heart,
and breast tumors. We demonstrate a careful integration of
statistical analysis (based on principal component analysis)
and interactive visualization with linked, multiple views.
