Integration Technologies for Smart Catheters

Around 10% of the population will have to go through a catheterization procedure for the treatment of a cardiovascular disease at a certain stage of their lives. During such a procedure, smart catheters will be the "eyes and ears" of the surgeons, significantly improving the diagnosis and treatment. However, there have been very limited...

Technology platform for advanced neurostimulation implants: The “chip-in-tip” DBS probe

The progress in the field of neurostimulation is impressive, both from a technical as well as from a therapeutic point of view. Nowadays, the electrical stimulation of the nervous system can be used to induce or suppress muscle responses. Additionally, it can also influence hearing, vision, immune system response, pain perception, and even...

Lamb Waves and Adaptive Beamforming for Aberration Correction in Medical Ultrasound Imaging

Phase aberration in transcranial ultrasound imaging (TUI) caused by the human skull leads to an inaccurate image reconstruction. In this article, we present a novel method for estimating the speed of sound and an adaptive beamforming technique for phase aberration correction in a flat polyvinylchloride (PVC) slab as a model for the human...

Spatial versus angular resolution for tractography-assisted planning of deep brain stimulation

Given the restricted total scanning time for clinical neuroimaging, it is unclear whether clinical diffusion MRI protocols would benefit more from higher spatial resolution or higher angular resolution. In this work, we investigated the relative benefit of improving spatial or angular resolution in diffusion MRI to separate two parallel...
