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

Microscale Mapping of Fiber Strain and Damage in Composite Wrinkled Laminates Using Computed Tomography Assisted Wide‐Angle X‐Ray Scattering

Advanced Science, EarlyView.
This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

Accidental transcutaneous displacement of a fiducial marker during transperineal prostate biopsy: a case report and narrative review

BMC Urology
Background Fiducial markers are commonly used to guide precise radiotherapy in prostate cancer patients. While intraprostatic migration has been described, transcutaneous displacement during biopsy is exceedingly rare.

Nanoscale Spatial Organization of ARC High‐ and Low‐Order Assemblies at Excitatory Synapses

Advanced Science, EarlyView.
ARC (Activity‐Regulated Cytoskeleton‐Associated protein) mediates synaptic plasticity by forming nanoscale assemblies in neurons. Using super‐resolution microscopy and time‐resolved anisotropy with targeted tagging, the study reveals low‐order ARC assemblies at synapses colocalizing with AMPARs, semi‐circular structures at endocytic zones, and 60–80 nm

Presentation Assistant and Kiosk Interaction with Fiducial Markers

2007 IEEE International Workshop on Haptic, Audio and Visual Environments and Games, 2007
Fiducial markers and computer vision software provide a low cost and flexible way for human-computer interaction. Using the high reliability and minimal image pixel requirements of the ARTag fiducial marker system we are able to identify users and perform control actions with a simple small printed pattern. We describe two novel applications.
