OpenCLIPER: An OpenCL-Based C++ Framework for Overhead-Reduced Medical Image Processing and Reconstruction on Heterogeneous Devices

OpenCLIPER performance vs. alternatives
[03 Jul 2019]

OpenCLIPER allows us to take advantage of any parallel computing device (CPUs, GPUs, FPGAs, DSPs, etc., as long as there is an OpenCL implementation for it), while developing medical imaging methods, but without the burden that OpenCL generally conveys. The work has been published in the IEEE Journal of Biomedical and Health Informatics journal.

Thesis distinction

[31 May 2019]

We are pleased to announce that Tomasz Pieciak has received a distinction for his thesis entitled "Non-stationary noise estimation in accelerated parallel MRI data" in the contest sponsored by the ABB HQ in Poland. The contest is organized in the area of technical sciences and includes theses defended in various fields such as advanced technologies and engineering systems, automation and industrial diagnostics, power electronics and technologies, and computer science systems.

 

The thesis was co-supervised by Prof. Santiago Aja-Fernández.

A Novel Second-Order Scheme for the Multi-Stencil Fast Marching Method

[12 Feb 2019]

A paper entitled "A Second Order Multi-Stencil Fast Marching Method With a Non-Constant Local Cost Model" has been recently published in the IEEE Transactions on Image Processing. The proposed scheme has been applied to optimal course planning of an unmanned aerial vehicle (UAV) in a flooding episode, and achieves better tradeoff between the distance travelled by the UAV and the amount of visited flooded land than previous state-of-the-art schemes of the Fast Marching method.

New Scalar diffusion-MRI measures proposed by the group

[07 Sep 2018]

An article entitled "Scalar diffusion-MRI measures invariant to acquisition parameters: A first step towards imaging biomarkers" has recently been published in the Magnetic Resonance Imaging journal (Elsevier). In that work, we propose a new set of quantitative measures based on diffusion magnetic resonance imaging from single-shell acquisitions that are designed to be robust to the variations of several acquisition parameters (number of gradient directions, b-value and SNR) while keeping a high discrimination power on differences in the diffusion characteristics of the tissue.

Project led by LPI member receives an Innovation Award in the UK

[04 Jun 2018]

The project "Low-pixel Automatic Target Detection and Recognition" led by Dr. Pablo Casaseca at University of the West of Scotland with multinational electrical systems group, Thales UK and CENSIS received a Special Commendation Award at the Scottish Knowledge Exchange Awards 2018 . This collaboration saw the development of unique technology, enabling automatic detection of humans and vehicles from up to 1500m using thermal imaging.
