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 ...

Organosilicon phantom for photoacoustic imaging
Journal of Biomedical Optics, 2015 Photoacoustic imaging is an emerging technique. Although commercially available photoacoustic imaging systems currently exist, the technology is still in its infancy. Therefore, the design of stable phantoms is essential to achieve semiquantitative evaluation of the performance of a photoacoustic system and can help optimize the properties of contrast ...

Comprehensive phantom for interventional fluorescence molecular imaging [PDF]
Journal of Biomedical Optics, 2016 Fluorescence imaging has been considered for over a half-century as a modality that could assist surgical guidance and visualization. The administration of fluorescent molecules with sensitivity to disease biomarkers and their imaging using a fluorescence camera can outline pathophysiological parameters of tissue invisible to the human eye during ...

Characterisation of a phantom for multiwavelength quantitative photoacoustic imaging
Physics in Medicine and Biology, 2016 Quantitative photoacoustic imaging (qPAI) has the potential to provide high- resolution in vivo images of chromophore concentration, which may be indicative of tissue function and pathology. Many strategies have been proposed recently for extracting quantitative information, but many have not been experimentally verified.
