A Rotational Cylindrical fMRI Phantom for Image Quality Control. [PDF]
PLoS ONE, 2015 A novel phantom for image quality testing for functional magnetic resonance imaging (fMRI) scans is described.The cylindrical, rotatable, ~4.5L phantom, with eight wedge-shaped compartments, is used to simulate rest and activated states. The compartments

Quantitative magnetic resonance imaging phantoms: A review and the need for a system phantom [PDF]
Magnetic Resonance in Medicine, 2017 The MRI community is using quantitative mapping techniques to complement qualitative imaging. For quantitative imaging to reach its full potential, it is necessary to analyze measurements across systems and longitudinally. Clinical use of quantitative imaging can be facilitated through adoption and use of a standard system phantom, a calibration ...

Anthropomorphic Breast and Head Phantoms for Microwave Imaging [PDF]
Diagnostics, 2018 This paper deals with breast and head phantoms fabricated from 3D-printed structures and liquid mixtures whose complex permittivities are close to that of the biological tissues within a large frequency band. The goal is to enable an easy and safe manufacturing of stable-in-time detailed anthropomorphic phantoms dedicated to the test of microwave ...

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada
Population Ecology, EarlyView.We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...
