2018 NeuroImage  
Brain extraction from images is a common pre-processing step. Many approaches exist, but they are frequently only designed to perform brain extraction from images without strong pathologies.  ...  This paper proposes a brain extraction approach which can explicitly account for pathologies by jointly modeling normal tissue and pathologies.  ...  , and EECS-1711776.  ...

Real time on-the-fly dynamic MRI for radiotherapy

Bryson Dietz
Therefore, there exists a trade-off between image quality and image acquisition speed.  ...  External beam radiotherapy (EBRT) utilizes high energy radiation (primarily photons or electrons) generated from a linear accelerator (linac) for the treatment of cancer.  ...  Discussion Dynamic PCA Image Reconstruction It is evident that CS-PCA reconstruction is an effective reconstruction technique for real-time dynamic imaging.  ...
