A tissue equivalent phantom for simultaneous near-infrared optical tomography and EEG

Evaluation of Reflection Optical Imaging Characteristics Using Fluorescence with Near Infrared Wavelength at Different Depths of Tissue Equivalent Phantom

A tissue-like optically turbid and electrically conducting phantom for simultaneous EEG and near-infrared imaging.

We describe a phantom for simultaneous electroencephalography (EEG) and near-infrared imaging which consists of a solid, optically turbid and electrically conducting interface enclosing a tissue-mimicking aqueous scattering solution. The interface provides an electrical contact impedance comparable to that of the human scalp while the phantom as a whole has optical properties and electrical con...

Development of a Liver Phantom Based on Computed Tomography Images for Dosimetric Purpose

Introduction: The present study was conducted with the aim of designing a liver phantom for dosimetry. To benchmark the results obtained by the developed liver phantom, another method was applied for the dosimetry of a real liver tissue using imaging. Materials and Methods: For the purpose of the study, a real liver tissue was converted into a phantom based on thegram-molecular weight of the co...

Design and evaluation of a probe for simultaneous EEG and NIR imaging of cortical activation

We present a novel probe design which enables simultaneous electroencephalography (EEG) and near-infrared (NIR) optical imaging to be performed in a manner which is easy to apply, allows for optimum coregistration of the two forms of data and maximizes the number of sensors which can be applied to a given area. Our probe design is evaluated using a dualmodality, tissue-mimicking phantom and by ...

Induction of Localized Hyperthermia by Millisecond Laser Pulses in the Presence of Gold-Gold Sulphide Nanoparticles in a Phantom

Introduction Application of near-infrared absorbing nanostructures can induce hyperthermia, in addition to providing more efficient  photothermal effects. Gold-gold sulfide (GGS) is considered as one of these nanostructures. This study was performed on a tissue-equivalent optical-thermal phantom to determine the temperature profile in the presence and absence of GGS and millisecond pulses of a ...
