Electrical properties of phantoms for mimicking breast tissue
2017 39th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2017In order to test and calibrate an EIT (Electrical Impedance Tomography) system, many researchers rely on phantoms mimicking breast tissues. These phantoms are usually made of saline solutions, agar and/or vegetables, allowing the user to set the conductivity of the material by changing the salt concentration.

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

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,

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 ...

Applications of the 1-D diffusion approximation to the optics of tissues and tissue phantoms
Applied Optics, 1989Optical constants of animal and plant tissues were measured over a wide spectral range using an integrating sphere spectrophotometer. The data were analyzed with two formulations of the 1-D diffusion approximation differing in the phase function.
