Order type dataset analysis for fiducial markers

Data in Brief, 2018
Order Type (OT) describes a point set avoiding the use of metric information. We show that OT is a descriptor which is invariant to Euclidean geometric transformations, change of scale and perspective projection. In this paper we provide the data related to the application of Order Type with sets of 5, 6, 7, and 8 points to build fiducial markers.

Traction Force Microscopy for Viscoelastic Substrates: A Semi‐Analytical Method

Advanced Science, EarlyView.
A semi‐analytical viscoelastic traction force microscopy framework is introduced for quantifying time‐resolved cell tractions on flat finite‐thickness substrates. The method generalizes elastic traction force microscopy to Generalized Maxwell materials, identifies when elastic approximations remain valid and, when they do not, shows that inferred ...

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.

Prostate fiducial marker detection with the use of multi-parametric magnetic resonance imaging

Physics and Imaging in Radiation Oncology, 2017
Background and purpose: The introduction of a magnetic resonance (MR)-only workflow in radiotherapy requires that fiducial markers, used for position verification, can be detected on MR images.

Ethical Precision in Nanoscale Brain Interfacing

Advanced Science, EarlyView.
As brain interfaces approach the nanoscale, precision no longer only measures—it knows, predicts, and potentially reshapes the mind. This work argues that traditional ethics fails under such conditions and proposes a shift toward continuous, operation‐based governance using the recovery–discovery framework to track, constrain, and responsibly steer ...

Optimization of a newly defined target volume in fiducial marker-based dynamic tumor-tracking radiotherapy

Physics and Imaging in Radiation Oncology, 2017
Background and purpose: To optimize the selection of fiducial markers used to determine the “internal target volume for tracking” (ITVtracking) for fiducial marker-based dynamic tumor-tracking (DTT) radiotherapy for lung tumors, with four-dimensional 320-

Application value of liquid fiducial marker in image-guided radiotherapy

Fushe yanjiu yu fushe gongyi xuebao, 2023
This study was conducted to evaluate the application value of a degradable liquid fiducial marker (LFM) in image-guided radiotherapy. In vitro experiment: using a solid fiducial marker (SFM) as a reference, the visibility, artifact, and optimal injection

Combining Spatial Multi‐Omics Data to Decipher Spatial Domains and Elucidate Cell Heterogeneity Based on Self‐Supervised Graph Learning

Advanced Science, EarlyView.
A self‐supervised multi‐view graph fusion framework integrates spatial multi‐omics, excelling in domain identification and denoising. It reconstructs spatial pseudo‐expression, jointly analyzes multi‐omics data, infers RNA velocity, predicts spatial omics features from single‐cell multi‐omics, and detects spatially dark genes and transcription factors,

Integrated Ultrasonic Platform for Bioelectronic Control through Biological Barriers Based on Metasurface

Advanced Science, EarlyView.
A metasurface‐enabled ultrasonic platform achieves precise multi‐focal control through biological barriers, real‐time physiology‐driven modulation, and simultaneous wireless power and data transmission. By unifying wavefront engineering, closed‐loop feedback, and acoustic communication, this work establishes key enabling technologies toward scalable ...
