Characterization of a flexible a-Si:H detector for in vivo dosimetry in therapeutic x-ray beams
Sylvain Dunand, Jonathan Emanuel Thomet, Luca Massimiliano Antognini, Matthew James Large
BackgroundThe increasing use of complex and high dose-rate treatments in radiation therapy necessitates advanced detectors to provide accurate dosimetry. Rather than relying on pre-treatment quality assurance (QA) measurements alone, many countries are now ...
Hoboken2024High-rate, high-resolution single photon X-ray imaging: Medipix4, a large 4-side buttable pixel readout chip with high granularity and spectroscopic capabilities
Jean-Michel Sallese, Adil Koukab, Viros Sriskaran
The Medipix4 chip is the latest member in the Medipix/Timepix family of hybrid pixel detector chips aimed at high -rate spectroscopic X-ray imaging using high -Z materials. It can be tiled on all 4 sides making it ideal for constructing large -area detecto ...
Iop Publishing Ltd2024A modular multiple frequency inductive link to wirelessly power multiple miniaturized implants
Sandro Carrara, Diego Ghezzi, Gian Luca Barbruni
A modular multiple frequency coils inductive link system to wirelessly provide power for at least a medical implant at an output of a receiving coil, whereby the receiving coil is configured to be implanted in an organism. The modular multiple frequency co ...
2024Medipix4, a high granularity four sides buttable pixel readout chip for high resolution spectroscopic X-ray imaging at rates compatible with medical CT scans
Medipix4 is the latest member in the Medipix/Timepix family of pixel detector chips aimed at high rate spectroscopic X-ray imaging using high-Z materials. The chip address the limitations of conventional hybrid pixel detectors for X-ray imaging. Its predec ...
EPFL2022AC Loss Measurement of the DEMO TF React&Wind Conductor Prototype No. 2
Pierluigi Bruzzone, Kamil Sedlák, Boris Stepanov
The EUROfusion DEMO is being designed as the fusion machine to be built after ITER. During the preconceptual phase, several design options are investigated by theoretical analyses as well as tests on newly developed conductor prototypes. One design option ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2020Characterization of Amorphous Silicon Based Microchannel Plates with High Aspect Ratio
Christophe Ballif, Janina Christine Isabelle Löffler
Microchannel plates (MCPs) fabricated out of hydrogenated amorphous silicon offer a promising alternative to conventional lead glass ones. Progress in the fabrication process has allowed for detectors with higher aspect ratios, which significantly increase ...
IEEE2019Demonstration of Multiple Kerr-Frequency-Comb Generation Using Different Lines From Another Kerr Comb Located Up To 50 km Away
Tobias Kippenberg, Maxim Karpov, Martin Hubert Peter Pfeiffer, Arne Kordts, Fatemeh Alishahi, Lin Zhang, Ahmad Fallahpour
On-chip Kerr frequency combs are potentially promising to enhance many applications because of their broad-band operation and chip-scale integration. Such combs offer various mutually coherent optical carriers that can potentially be used as both coherent ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2019Ghostbuster: Detecting the Presence of Hidden Eavesdroppers
Haitham Al Hassanieh, Jiaming Wang, Jiachen Sun
This paper explores the possibility of detecting the hidden presence of wireless eavesdroppers. Such eavesdroppers employ passive receivers that only listen and never transmit any signals making them very hard to detect. In this paper, we show that even pa ...
Association for Computing Machinery2018On Rendering Synthetic Images for Training an Object Detector
Pascal Fua, Vincent Lepetit, Artem Rozantsev
We propose a novel approach to synthesizing images that are effective for training object detectors. Starting from a small set of real images, our algorithm estimates the rendering parameters required to synthesize similar images given a coarse 3D model of ...
Elsevier2015Exploiting Scene Cues for Dropped Object Detection
Jean-Marc Odobez, Florent Monay Michaud
This paper presents a method for the automated detection of dropped objects in surveillance scenarios, which is a very important task for abandoned object detection. Our method works in single views and exploits prior information of the scene, such as geom ...
