ViP MRI: virtual phantom magnetic resonance imaging

Magnetic Resonance Materials in Physics, Biology and Medicine, 2013
The ability to generate reference signals is of great benefit for quantitation of the magnetic resonance (MR) signal. The aim of the present study was to implement a dedicated experimental set-up to generate MR images of virtual phantoms.Virtual phantoms of a given shape and signal intensity were designed and the k-space representation was generated. A

Feasibility of simultaneous intracranial EEG-fMRI in humans: a safety study [PDF]

, 2010
In epilepsy patients who have electrodes implanted in their brains as part of their pre-surgical assessment, simultaneous intracranial EEG and fMRI (icEEG-fMRI) may provide important localising information and improve understanding of the underlying ...

Designing microarray phantoms for hyperspectral imaging validation

Biomedical Optics Express, 2012
The design and fabrication of custom-tailored microarrays for use as phantoms in the characterization of hyperspectral imaging systems is described. Corresponding analysis methods for biologically relevant samples are also discussed. An image-based phantom design was used to program a microarrayer robot to print prescribed mixtures of dyes onto ...

Tissue-like phantoms for quantitative birefringence imaging

Biomedical Optics Express, 2017
Birefringence imaging, including polarization sensitive optical coherence tomography (PS-OCT), can provide valuable insight into the microscopic structure and organization of many biological tissues. In this paper, we report on a method to fabricate tissue-like birefringence phantoms for such imaging modalities.
