So far, one of the major obstacles to the development of special purpose MRI imaging apparatus has been the lack of a magnetic technology that could cater to the need for a light, compact and efficient magnet, capable of providing the required field uniformity at a reasonable cost. Today, recent advances in magnet design permit attaining, with the use(More)
In this paper, the harmonic beamforming, a technique proposed by the authors to improve the harmonic imaging process in medical echography, is shortly presented. It relies on a modification to the delays used in reception beamforming that allows one to sharply reduce the echoes centered at the fundamental frequency and to keep the echoes centered at the(More)
A study of the motor cortex during the programming, execution and mental representation of voluntary movement is of great relevance; its evaluation in conditions close to reality is necessary, given the close integration of the visuomotor, sensory feedback and proprioceptive systems, as of yet, a functional Magnetic Resonance Imaging (fMRI) scanner allowing(More)
An innovative method for the preparation of elastomeric magnetic films with increased magneto-responsivity is presented. Polymeric films containing aligned magnetic microchains throughout their thickness are formed upon the magnetophoretic transport and assembly of microparticles during polymer curing. The obtained films are subsequently magnetized at a(More)
In this work we investigate how the tactile detection thresholds of air-driven actuators are influenced by design parameters as membrane thickness and diameter, when the finger is in contact with the deformable circular elastic membranes. We report lower thresholds with decreasing membrane thickness and increasing diameters. These results can help in the(More)
