Fetal Brain MRI

In Collaboration with 

Fetal brain MRI provides high contrast and resolution images of the developing brain. It suffers, however, from uncontrollable fetal head motion that may occur during the scan. This effect is illustrated in Fig. 1 for two consecutive slices.  As a result, fetal brain is not sampled at regular, orthogonal intervals but rather along a set of mutually misaligned planes, similar to a disordered stack of playing cards.

  

In these conditions, fetal MRI fails to provide a good 3-D approximation of the fetal brain, leading to increased risk of misdiagnosis.

The goal of this project is to develop a reconstruction algorithm that given several motion corrupted fetal brain scans, acquired in different imaging planes, will generate a single high resolution isotropic 3-d brain image volume. This will enable the Radiologist to observe brain anatomy in any re-slicing plane as can be done with high resolution adult brain MRI.
