Fast quantitative susceptibility mapping with L1-regularization and automatic parameter selection.
PURPOSE To enable fast reconstruction of quantitative susceptibility maps with total variation penalty and automatic regularization parameter selection. METHODS ℓ(1) -Regularized susceptibility mapping is accelerated by variable splitting, which allows closed-form evaluation of each iteration of the algorithm by soft thresholding and fast Fourier transforms. This fast algorithm also renders a...
متن کاملQuantitative Susceptibility Mapping: A comparison between COSMOS and weighted L1 regularization from single orientation
Introduction: Quantitative Susceptibility Mapping (QSM) provides both visualization and quantification of endogenous and exogenous susceptibility contrast. Finding the susceptibility distribution from the measured field map requires a deconvolution of that field map with the unit dipole response, a process which is ill-posed [1]. Several techniques have been proposed to solve the problem by mul...
متن کاملDiagnosis of patients with Parkinson's disease using quantitative susceptibility mapping
Introduction: Parkinson'sdisease isassociated withirondeposition in the brain. The T2-weighted imaging, T2* mapping, R2 mapping and Quantitative Susceptibility Mapping (QSM) are three common methods to evaluating the iron deposition in brain. Among three methods the QSM is more sensitive than others. Few studies have been used QSM for evaluating the iron deposition in the basa...
متن کاملFast Learning with Nonconvex L1-2 Regularization
Convex regularizers are often used for sparse learning. They are easy to optimize, but can lead to inferior prediction performance. The difference of `1 and `2 (`1-2) regularizer has been recently proposed as a nonconvex regularizer. It yields better recovery than both `0 and `1 regularizers on compressed sensing. However, how to efficiently optimize its learning problem is still challenging. T...
متن کاملAnimal imaging using L1-regularized Quantitative Susceptibility Mapping
Introduction: Quantitative susceptibility mapping (QSM) is a technique that uses phase data from an MRI image to estimate the susceptibility distribution in the object. It has been demonstrated that QSM is able to correctly estimate the magnetic moment of specimen differing in susceptibility to the surrounding tissue [1]. We would like to exploit this ability to perform quantitative imaging of ...
