Experimental validation of a high-resolution diffuse optical imaging modality: photomagnetic imaging

Quantitative molecular imaging with a dual modality MR and fluorescence diffuse optical imaging system: phantom study

Introduction : Molecular imaging has become an essential tool in characterization and measurement of biological process at the molecular or cellular level. In vivo small animal studies have shown the feasibility of using MRI to investigate gene expression and stem cell migration with superparamagnetic iron nanoparticles [1]. However, even though MRI provides excellent anatomical information, th...

A Dual Modality System for High Resolution - True Conductivity Imaging

In this study, a dual modality imaging system which utilises the magnetic flux density measurements, acquired using Magnetic Resonance Current Density Imaging (MRCDI) techniques, and the surface potential measurements, obtained from conventional Electrical Impedance Tomography (EIT) techniques, to reconstruct high resolution absolute conductivity images. An iterative algorithm is developed to m...

Diffuse Optical Imaging

Diffuse optical imaging is a functional medical imaging modality which takes advantage of the relatively low attenuation of near-infrared light to probe the internal optical properties of tissue. The optical properties are affected by parameters related to physiology such as the concentrations of oxyand deoxyhemoglobin. Instrumentation that is used for optical imaging is generally able to measu...

Diffuse optical imaging.

Diffuse optical imaging is a medical imaging technique that is beginning to move from the laboratory to the hospital. It is a natural extension of near-infrared spectroscopy (NIRS), which is now used in certain niche applications clinically and particularly for physiological and psychological research. Optical imaging uses sophisticated image reconstruction techniques to generate images from mu...
