Sinus Veins


My daughter's sinus veins (the big veins draining the blood coming from the brain). Nothing wrong with them :)

My first tests with MRI data. MRIs usually produce data series with lower resolutions than those of a CT. Also, since the physics underlying the creation of pictures in CT and MRI are very different, usual procedures to segmentate pictures as used with CT can't be applied here. The data used for pictureing the veins of the brain are of a slightly higher resolution. And the object depicted, i.e. the blood flow in the veins, gives a high signal compared to the surroundings which can be used to segmentate data. I thought about showing a brain but I'm not there yet...
