The role of a radiopaque peri-rectal hydrogel spacer in aiding accurate daily image-guidance for prostate stereotactic radiotherapy

Frontiers in Oncology
IntroductionPrecise patient positioning with image guidance (IGRT) is essential for safe prostate radiotherapy. We present the first report of utilizing a CT-visible hydrogel spacer, used to decrease rectal radiation dose, as a surrogate fiducial marker ...

Robust Tracking Through the Design of High Quality Fiducial Markers: An Optimization Tool for ARToolKit

IEEE Access, 2018
Fiducial markers are images or landmarks placed in real environment, typically used for pose estimation and camera tracking. Reliable fiducials are strongly desired for many augmented reality (AR) applications, but currently there is no systematic method

Probing the peak of the star formation rate density with the extragalactic background light

, 2012
The extragalactic background light (EBL), i.e., the diffuse meta-galactic photon field in the ultraviolet to infrared, is dominated by the emission from stars in galaxies.

Fractal Markers: A New Approach for Long-Range Marker Pose Estimation Under Occlusion

IEEE Access, 2019
Squared fiducial markers are a powerful tool for camera pose estimation in applications such as robots, unmanned vehicles and augmented reality. The four corners of a single marker are enough to estimate the pose of a calibrated camera.

D-touch: A Consumer-Grade Tangible Interface Module and Musical Applications

, 2003
We define a class of tangible media applications that can be implemented on consumer-grade personal computers. These applications interpret user manipulation of physical objects in a restricted space and produce unlocalized outputs.

Human coronary artery organ‐chip with circulating immune cells recapitulates anti‐inflammatory effect of pulsatile wall strain

Interdisciplinary Medicine, EarlyView.
A fully characterised organ‐on‐a‐chip model of the human coronary artery with endothelial and smooth muscle cells, plus circulating immune cells, created on the Emulate platform. The model successfully recapitulates the physiological effects of pulsatile vessel dilation on cell morphology and the localised inflammatory susceptibility to TNF‐α ...

Microscopic tumor spread beyond (echo)endoscopically determined tumor borders in esophageal cancer

Radiation Oncology, 2019
Objective The microscopic tumor spread (MS) beyond the macroscopic tumor borders of esophageal tumors is crucial for determining the clinical target volume (CTV) in radiotherapy. The question arises whether current voluminous CTV margins of 3–5 cm around

Observing dust settling and coagulation in circumstellar discs: Selected constraints from high resolution imaging

, 2010
Circumstellar discs are expected to be the nursery of planets. Grain growth within such discs is the first step in the planet formation process in the core-accretion gas-capture scenario.
