Towards a Phantom for Multimodality Performance Evaluation of Breast Imaging: A 3D Structured Phantom with Simulated Lesions Tested for 2D Digital Mammography KU Leuven
© Springer International Publishing Switzerland 2016. The aim of this work is to test whether a 3D structured phantom with simulated lesions can be used for performance evaluation of 2D digital mammography, as a step towards a multimodality phantom. A phantom, developed for breast tomosynthesis was therefore applied on 23 digital mammography systems. Ten images were acquired at the clinically used dose and for 11 systems also at half and double ...
Custom lifetime phantoms for characterization and benchmarking of a new CAPS fluorescence-lifetime camera Vrije Universiteit Brussel
Fluorescence imaging has been used for quite some time in microscopy, preclinical and medical imaging, as well as in other domains. There has been interest in using the time-behaviour of fluorophores to gain additional information. This time-behaviour, called the fluorescence lifetime, is a property of the fluorophore and can also reveal information about its environment through modulation of this lifetime. Fluorescence-lifetime imaging could ...
Ground truth hardware phantoms for validation of diffusion-weighted MRI applications Ghent University
Purpose: To quantitatively validate diffusion-weighted MRI (DW-MRI) applications, a hardware phantom containing crossing fibers at a sub-voxel level is presented. It is suitable for validation of a large spectrum of DW-MRI applications from acquisition to fiber tracking, which is an important recurrent issue in the field. Materials and Methods: Phantom properties were optimized to resemble properties of human white matter in terms of anisotropy, ...
Investigation of technical variability in ASL data using MR phantoms Ghent University
Introduction: Arterial Spin Labeling (ASL) is a non-invasive MR imaging technique used to quantify perfusion, showing high promise for the diagnosis of many neurological and psychiatric disorders1. However, the clinical application of ASL is limited due to the possible influence of technical factors such as scanner and coil variability. To address this limitation, MR phantoms, such as the Quantitative Arterial Spin Labeling Perfusion Reference ...
Piezoelectric Tactile Sensor using Multisine Excitation for Differentiation of Biological Tissues and Phantoms Vrije Universiteit Brussel
Brain tumor surgery is a complex task that relies critically on a correct identification of tumor boundaries based on visual and tactile impressions performed by neurosurgeons. The information of the pre-operative 3D coordinates of the tumor provided by imaging techniques (e.g. Magnetic Resonance Imaging) will differ from the real position at the moment the skull is opened due to brain shift phenomenon. Thus, the development of assisting tools ...
Imaginary Europes, Phantoms of the Past, Conceptions of the Future? Vrije Universiteit Brussel
The 20th century has witnessed crucial changes in our perceptions of Europe. Two World Wars and many regional conflicts, the end of empires and of the Eastern Bloc, the creation and expansion of the European Union, and the continuous reshaping of Europe’s population through emigration, immigration, and globalization have led to a proliferation of images of Europe within the continent and beyond. While Eurocentrism governs current public debates ...
Detectability of artificial lesions in anthropomorphic virtual breast phantoms of variable glandular fraction KU Leuven
© 2017 SPIE. This work seeks to utilize a cohort of computational, patient-based breast phantoms and anthropomorphic lesions inserted therein to determine trends in breast lesion detectability as a function of several clinically relevant variables. One of the measures of local density proposed gives rise to a statistically significant trend in lesion detectability, and it is apparent that lesion type is also a predictor of relative detectability....
Mesh modeling of system geometry and anatomy phantoms for realistic GATE simulations and their inclusion in SPECT reconstruction Interuniversity Microelectronics Centre University of Antwerp
Objective. Monte-Carlo simulation studies have been essential for advancing various developments in single photon emission computed tomography (SPECT) imaging, such as system design and accurate image reconstruction. Among the simulation software available, Geant4 application for tomographic emission (GATE) is one of the most used simulation toolkits in nuclear medicine, which allows building systems and attenuation phantom geometries based on ...
