The LPI has gained a national grant for the research project entitled "t-WiSE-MR: ECG-Free, Free-Breathing Cardiac CINE MRI: High Quality Reconstruction from Subsampled k-space using a Groupwise Motion Correction Paradigm". The grant is funded by Ministerio de Ciencia e Innovación (Spain) from January 2015 to December 2017.
A new probabilistic tissue characterization for ultrasound images implementation has been published in the Insight Journal: "Probabilistic Tissue Characterization for Ultrasound Images".
A new speckle tracking (ST) method for 3D Strain Estimation in Echocardiography has been published in the international journal Medical Image Analysis: "A Maximum Likelihood Approach to Diffeomorphic Speckle Tracking for 3D Strain Estimation in Echocardiography".
A new MRI reconstruction method for highly undersampled dynamic data in the international journal Magnetic Resonance in Medicine: "Nonrigid groupwise registration for motion estimation and compensation in compressed sensing reconstruction of breath-hold cardiac cine MRI".
The website of the "Agencia Iberoamericana para la difusión de la ciencia y la tecnología" gathers information about an ultrasound oriented designed by the LPI: A new device improves the quality of ultrasound scans.
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)".
A new methodology for reconstruction of subsampled multi-coil MRI data has been published in the International Journal of Computer Assisted Radiology and Surgery: "Improving GRAPPA reconstruction by frequency discrimination in the ACS lines".
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.
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.
Dentro de su ciclo de seminarios formativos, el LPI organiza una sesión sobre Resonancia Magnética de Difusión (DMRI) desde el punto de vista de procesado de señal. Los seminarios se engloban dentro de las actividades formativas del programa de doctorado del Departamento de Teoría de la Señal, Comunicaciones e Ing. telemática de la Universidad de Valladolid. "Introducción a la Resonancia Magnética de Difusión", viernes 20 de marzo de 2015, 12:00, seminario Haykin. Ponente: Antonio Tristán Vega
