Abstract The key to designing an implantable device lies in condensing the synergistic effects of diagnostic and therapeutic methods a single tool. In conjunction with integration electrophysiology optical modalities, transparent neural interface alleviates challenges conventional metal-based microelectrodes. this review, multimodal sensing stimulation functionalities recent research are addres...

Examples of a few objects are presented, where the electron microprobe has proved that it can provide the conservator and the curator with information that will help in evaluating the authenticity of a particular art object. They will also obtain a better understanding of how an object was fabricated and what materials it was made from. The results of the analysis of paint samples, samples from...

A new method for reducing metal artifacts in X-ray computed tomography (CT) images is presented. It bases on the solution of a convex optimization problem with inequality constraints on the sinogram, and total variation regularization for the reconstructed image. The Chambolle-Pock algorithm is used to numerically solve the discretized version of the optimization problem. As proof of concept we...

Imaging of the cerebral vessels with use of CT angiogram (CTA) after placement of aneurysmal clips is often limited by clip artifacts. We used a phantom to demonstrate a visible reduction in metal artifact when using the axial technique, compared with the usual CTA helical acquisition. This approach may have some advantage when used for CTA with 64-section scanners in the specific circumstance ...
