Toward a reference standard for tissue phantoms
SPIE Proceedings, 2011A reference standard for tissue-simulating phantoms, i.e., a phantom with well known and stable optical properties, reproducible, and easy to be found, would be very useful for many applications based on measurements of diffused light. Although many tissue-equivalent phantoms have been proposed, to our knowledge none of them has been characterized ...

Generation of 3D Digital Phantoms of Colon Tissue
2011Although segmentation of biomedical image data has been paid a lot of attention for many years, this crucial task still meets the problem of the correctness of the obtained results. Especially in the case of optical microscopy, the ground truth (GT), which is a very important tool for the validation of image processing algorithms, is not available ...

Spectral variations in tissues and phantoms.
Ultrasound in medicine & biology, 1986This paper is concerned with the characterization of attenuation in tissue. A simple method for measuring frequency dependent attenuation is demonstrated. The effects of frequency dependent scatter on the measurement of attenuation are also considered in order to determine the theoretical and practical ramifications of this interfering effect. Finally,

An anisotropic thermal phantom of perfused tissue
Proceedings of the 1988 Fourteenth Annual Northeast Bioengineering Conference, 2003Initial development and test of instruments for measuring anisotropic conductivity in vivo is difficult to carry out in animal models and would benefit from trials in a nonbiological physical model, a phantom. Here, a phantom that conducts heat anisotropically is described. The phantom also mimics the small-scale temperature nonuniformities that may be

Thermoelastic Signatures of Tissue Phantom Absorption and Thermal Expansion
IEEE Transactions on Biomedical Engineering, 1987A microwave-induced thermoelastic pressure wave method for imaging of biological tissues has been investigated. Liquid-filled test tubes inside a water tank were used as phantom models. A pulsed 2.45 GHz microwave source and a hydrophone transducer were used to generate and to detect thermoelastic pressure waves. A pattern extraction algorithm was used

Dynamically programmable digital tissue phantoms
SPIE Proceedings, 2008As optical imaging modalities gain acceptance for medical diagnostics and become common in clinical applications, standardized protocols to quantitatively assess optical sensor performance are required to ensure commonality in measurements and to validate system performance.

Rapid detection of inhomogeneity in a tissue phantom
2003 IEEE 29th Annual Proceedings of Bioengineering Conference, 2003Detecting inhomogeneity in a turbid tissue using an optical tomography technique as a non-invasive tool is of paramount importance in imaging and diagnosis of diseases and tissue abnormalities. In our approach, an ultrafast laser is used as the detecting source and the backscattered light signals are collected around the boundary of the target. We have

A new tissue-mimicking material for phantoms
2015 IEEE International Ultrasonics Symposium (IUS), 2015We present a tissue-mimicking material for the phantom of medical diagnostic instruments. Accurate testing of an instrument by phantoms requires a tissue-mimicking material that has the acoustic velocity, density, and attenuation defined in the International Electrotechnical Commission (IEC) standard, and furthermore the tissue-mimicking material must ...
