VISUALIZATION OF CHANGES IN MAGNETIC RESONANCE IMAGE DATA
K. Suomi, J. Oikarinen
Computer assisted image fusion provides an easy and accurate
way to interpret and compare medical image
pairs. Subjective expectations of human interpretator become less
important when pixel-by-pixel-variations are calculated by
computer. The estimation of sizes and locations of the differences
also become more exact. We introduce new methods to visualize
changes between images and present examples how they can be used to
highlight contrast medium trace and to follow growth of brain tumor in
MRI. The composite images created using these methods provide an
illustrative way to discover faint or small-sized differences between
separate volumes.
