Neural electrode interfaces are essential to the stimulation safety and recording quality of various bioelectronic therapies. The recently proposed hierarchical platinum-iridium (Pt-Ir) electrodes produced by femtosecond lasers have exhibited superior electrochemical performance in vitro, but their vivo is still unclear. In this study, we explored performance, biological response, tissue adhesion Pt-Ir implantation adult rat brains for 1, 8, 16 weeks. Regular smooth were used as a control....
Radio frequency (RF)-induced heating associated with medical implants is a critical concern when performing magnetic resonance imaging (MRI) scan.

Its properties are unclear and research on how to choose an unaffected measurement region is insufficient....
Magnetic resonance imaging and active implantable medical devices are both powerful tools for neuroscience research their interaction poses potential safety concerns to patients. Radiofrequency-induced heating is the most pernicious complex issue. The electrode tip region main site. Meanwhile, also affects electromagnetic model as well its measurement process of device. However, only parameter used evaluate influence impedance. In this study, we analyzed radiofrequency-induced evaluation...
Abstract Radio frequency induced heating of medical implants during magnetic resonance imaging (MRI) poses a serious threat to patient safety, and in vivo assessment permits individualized on-site safety assessment. Based on the proton (PRF) thermometry, we developed method for evaluation implant heating. It combined PRF signals around with bioheat transfer law reduce interference metal artifacts estimate RF at surface. To apply this idea, proposed PRF-based test module consisting processes...
Deep brain stimulation (DBS) is an effective treatment for neurological disorders, and accurately reconstructing the DBS lead trajectories crucial MRI compatibility assessment surgical planning. This paper presents a novel fully automated framework from postoperative CT images. The leads were first segmented by thresholding, but would be fused together somewhere. Mean curvature analysis of multi-layer number isosurfaces was introduced to effectively address fusion, due different topological...
