Method for bias field correction of brain T1-weighted magnetic resonance images minimizing segmentation error.
This work presents a new algorithm (nonuniform intensity correction; NIC) for correction of intensity inhomogeneities in T1-weighted magnetic resonance (MR) images. The bias field and a bias-free image are obtained through an iterative process that uses brain tissue segmentation. The algorithm was validated by means of realistic phantom images and a set of 24 real images. The first evaluation p...
متن کاملFully Automatic Method for 3D T1-Weighted Brain Magnetic Resonance Images Segmentation
Accurate segmentation of brain MR images is of interest for many brain disorders. However, due to several factors such noise, imaging artefacts, intrinsic tissue variation and partial volume effects, brain extraction and tissue segmentation remains a challenging task. So, in this paper, a full automatic method for segmentation of anatomical 3D brain MR images is proposed. The method consists of...
متن کاملA RVR-based Method for Bias Field Estimation in Brain Magnetic Resonance Images Segmentation
This paper presents a relevance vector regression (RVR) based parametric approach to the bias field estimation in brain magnetic resonance (MR) image segmentation. Segmentation is a very important and challenging task in brain analysis, while the bias field existed in the images can significantly deteriorate the performance. Most of current parametric bias field correction techniques use a pre-...
متن کاملSegmentation of Brain MR Images with Bias Field Correction
We consider a statistical model-based approach to the segmentation of magnetic resonance (MR) images with bias field correction. The proposed method of penalized maximum likelihood is implemented via the expectationconditional maximization (ECM) algorithm, using an approximation to the E-step based on a fractional weight version of the iterated conditional modes (ICM) algorithm. A Markov random...
متن کاملBrain segmentation performance using T1-weighted images versus T1 maps
The recent driven equilibrium single-pulse observation of T1 (DESPOT1) approach permits real-time clinical acquisition of large-volume and high-isotropic-resolution T1 mapping of MR tissue parameters with improved uniformity. It is assumed that the quantitative nature of maps will facilitate clinical applications such as disease diagnosis and comparison across subjects. However, there is not ye...
