The utility of currently available cortical prosthetic vision systems is disappointing. The essential features of a neuromorphic device that is predicted to enhance vision provided by available systems follow from a hypothesis which states that the objective and subjective aspects of cortical prosthetic vision jointly constitute patterns that emerge from specified synaptic interactions. The research reported here completes several required steps in developing an emulation of this device: (1) replication of small-scale simulations that are consistent with the hypothesis using the NEST (Écublens

Prebiopsy multiparametric prostate MRI (mp-MRI), followed by transrectal ultrasound-guided (TRUS-G) target biopsies (TB) of the prostate is a key combination for the diagnosis of clinically significant prostate cancers (CSPCa), to avoid prostate cancer (PCa) overtreatment. Several techniques are available for guiding TB to the suspicious mp-MRI targets, but the simplest, cheapest, and easiest to learn is “cognitive,” with visual registration of MRI and TRUS data. This review details the successive steps of the method (target detection, mp-MRI reporting, intermodality fusion, TRUS guidance to t

AbstractMillions of people around the world have lost their upper limbs mainly due to accidents and wars. Recently in the Middle East, the demand for prosthetic limbs has increased dramatically due to ongoing wars in the region. Commercially available prosthetic limbs are expensive while the most economical method available for controlling prosthetic limbs is the Electromyography (EMG). Researchers on EMG-controlled prosthetic limbs are facing several challenges, which include efficiency problems in terms of functionality especially in prosthetic hands. A major issue that needs to be solved is

Abstract With the vigorous development of electronic technology and computer technology, as well as the continuous advancement of research in the fields of neurophysiology, bionics and medicine, the artificial visual prosthesis has brought hope to the blind to restore their vision. Artificial optical prosthesis research has confirmed that prosthetic vision can restore part of the visual function of patients with non-congenital blindness, but the mechanism of early prosthetic image processing still needs to be clarified through neurophysiological research. The purpose of this article is to stud

Visual prostheses, used to assist in restoring functional vision to the visually impaired, convert captured external images into corresponding electrical stimulation patterns that are stimulated by implanted microelectrodes to induce phosphenes and eventually visual perception. Detecting and providing useful visual information to the prosthesis wearer under limited artificial vision has been an important concern in the field of visual prosthesis. Along with the development of prosthetic device design and stimulus encoding methods, researchers have explored the possibility of the application of

Retinal prosthetic devices aim to repair some vision in visually impaired patients by electrically stimulating neural cells in the visual system. Although there have been several notable advancements in the creation of electrically stimulated small dot-like perceptions, a deeper comprehension of the physical properties of phosphenes is still necessary. This study analyzes the influence of two independent electrode array topologies to achieve single-localized stimulation while the retina is electrically stimulated: a two-dimensional (2D) hexagon-shaped array reported in clinical studies and a p

Electrical stimulation of the retina affected by photoreceptor loss (e.g., cases of retinitis pigmentosa) elicits the perception of luminous spots (so-called phosphenes) in the visual field. This phenomenon, attributed to the relatively high survival rates of neurons comprising the retina's inner layer, serves as the cornerstone of efforts to provide a microelectronic retinal prosthesis -- a device analogous to the cochlear implant. This thesis concerns phosphenes -- their elicitation and modulation, and, in turn, image analysis for use in a prosthesis. This thesis begins with a comparative r

Ces travaux s'inscrivent dans le cadre plus général de la réalisation d'une prothèse visuelle, destinée aux personnes atteintes de cécité tardive due à une maladie dégénérative des cellules photo réceptrices de la rétine. Par la stimulation adéquate de certaines parties des voies optiques encore fonctionnelles, il est possible de transmettre à nouveau des perceptions visuelles, appelées phosphènes, dans le champ visuel du patient. Les études actuelles portant sur le contenu informationnel de cette vision prothétique proposent simplement de réduire la résolution de l'image d'une caméra embarqué

La cécité touche 39 millions de personnes dans le monde et génère de nombreuses difficultés dans la vie quotidienne. Plus précisément, les capacités de navigation (incluant orientation et mobilité) sont fortement diminuées, ce qui amène les personnes non-voyantes à limiter, voire à cesser leurs déplacements. Pour restaurer des sensations "visuelles", et par-delà, une certaine autonomie, il est possible de stimuler directement le système visuel résiduel d'une personne non-voyante à l'aide d'un implant administrant des micro-stimulations électriques.

Prostate cancer is one of the most common cancers in the UK, and Robotic-Assisted Surgery (RAS) has become a common method for prostate cancer surgery. Sentinel lymph node biopsy (SLNB) is an important component of prostate cancer surgery and provides accurate diag- nostic evidence of disease extent. A drop-in gamma probe, SENSEI, has been designed to improve the accuracy of sentinel lymph node detection in RAS. An example of its in vivo usage can be seen in Figure 1. It can distinguish cancerous tissue from normal tissue by detecting the radiation emitted from radiolabeled probes that have be

Transtibial amputation (TTA) patients face ongoing morphological changes in their residual limb. The residuum volume changes due to weight gain or loss, diurnal edema, and muscle atrophy. Consequently, the TTA prosthetic-user is fitted with a new prosthetic socket approximately every four years. Despite new innovations in socket and liner materials and design, contemporary prosthetics are not yet equipped to confront these changes. The TTA residual limb is therefore subjected to high superficial and internal stresses which may cause injury. Appending the hazardous condition of natural volume c
