New MRI reconstruction method presented at ISMRM 2015
A new recontruction method for Single Breath Hold, Whole Heart Cardiac Cine MRI have been accepted for presentation at the 23rd Annual Meeting of the International Society of Magnetic Resonance in Medicine: "Single Breath Hold Whole Heart Cine MRI With Iterative Groupwise Cardiac Motion Compensation and Sparse Regularization (kt-WiSE)".
New GRAPPA MRI recontruction method published
New thresholding methodology published
A new methodology for image thresholding has been recently proposed and published in Knowledge Based Systems: "A local fuzzy thresholding methodology for multiregion image segmentation". The methodology overcomes the common drawbacks of thresholding methods when images are corrupted with artifacts and noise. It is based on relating each pixel in the image to different output centroids via a fuzzy membership function, avoiding any initial hard decision.
LPI at the ISBI 2015
The LPI was present in 2015 IEEE International Symposium on Biomedical Imaging (ISBI), hold last April at Brooklyn, NY. ISBI is a joint initiative of the IEEE Signal Processing Society (SPS) and IEEE Engineering in Medicine and Biology Society (EMBS). A communication was sent following one of the reserach lines of the group (MRI noise analysis), entitled Blind Estimation of Spatially Variant Noise in GRAPPA MRI.
