COMMIT: Convex Optimization Modeling for Microstructure Informed Tractography

Jean-Philippe Thiran, Alessandro Daducci, Alia Lemkaddem

Tractography is a class of algorithms aiming at in vivo mapping the major neuronal pathways in the white matter from diffusion MRI data. These techniques offer a powerful tool to noninvasively investigate at the macroscopic scale the architecture of the ne ...

Modeling of Reconfigurable Medical Ultrasonic Applications in BIP

Alena Simalatsar, Stefanos Skalistis

Medical ultrasonic imaging applications require high quality of images produced in real-time often with limited resources available. Deadlock-freedom and confluency must be guaranteed to insure the correctness of the applications, while feasibility and opt ...

Low Power and Scalable Many-Core Architecture for Big-Data Stream Computing

David Atienza Alonso, Karim Kanoun, Martino Ruggiero

In the last years the process of examining large amounts of different types of data, or Big-Data, in an effort to uncover hidden patterns or unknown correlations has become a major need in our society. In this context, stream mining applications are now wi ...

Virtual Ways: Low-Cost Coherence for Instruction Set Extensions with Architecturally Visible Storage

Edoardo Charbon, Paolo Ienne, Ties Jan Henderikus Kluter, Samuel Burri, Philip Brisk

Instruction set extensions (ISEs) improve the performance and energy consumption of application-specific processors. ISEs can use architecturally visible storage (AVS), localized compiler-controlled memories, to provide higher I/O bandwidth than reading da ...

Decline of Fiber Tract Integrity Over the Adult Age Range: A Diffusion Spectrum Imaging Study

Kieran O'Brien

Purpose: We applied a novel diffusion spectrum imaging (DSI) acquisition to determine associations between aging and subcortical fiber tract integrity. Materials and Methods: We studied 35 cognitively healthy subjects (17 women), spanning the adult age ran ...
