Partial volume correction of quantitative susceptibility maps for oxygen extraction fraction measurements

Research output: Contribution to conferenceAbstractOther

Abstract

Partial volume effects impede the use of quantitative susceptibility maps for assessing small veins. Oxygen extraction fraction measures are particularly sensitive to these effects. We propose a geometric technique for calculating partial volume from binary venograms. The technique is able to calculate accurate partial
volume maps, and vessel geometry, on simulated veins of sub-voxel radius. These partial volume maps are used to adjust for partial volume effects in estimating venous magnetic susceptibility.
