Three-dimensional impedance map analysis of rabbit liver

Three-dimensional impedance map analysis of rabbit liver.

Three-dimensional impedance maps (3DZMs) are computational models of acoustic impedance of tissue constructed from histology images. 3DZMs can be analyzed to estimate model-based quantitative ultrasound parameters such as effective scatterer diameter (ESD). In this study, 3DZMs were constructed from normal and fatty rabbit livers. Estimates of ESD were made using the fluid-filled sphere scatter...

Three - Dimensional Impedance Map Analysis of Biological Tissue To

Three-dimensional impedance maps (3DZMs) are computational models of acoustic impedance of tissue constructed from a series of adjacent histology images. The power spectrum of a 3DZM can be analyzed to estimate model-based quantitative ultrasound parameters such as effective scatterer diameter (ESD) and effective acoustic concentration (EAC). The goal in this approach is to determine a link bet...

Three- dimensional Effects in Electrical Impedance Tomography

An investigation of 3-dimesional (3D) effects on electrical impedance tomography is reported. 3D effects in measurement, simulation and analytical models are described. A 3D attenuation range (75% attenuation) from the sensing plane is suggested as one third of process vessel’s diameter. The imaging trajectory of an axially moving object is found towards the central axis of a process vessel whe...

Three-dimensional reconstruction of New Zealand rabbit antebrachium by multidetector computed tomography

The aim of this study was to reveal biometric peculiarities of New Zealand white rabbit antebrachium (radius and ulna) by means of three-dimensional (3D) reconstruction of multidetector computed tomography (MDCT) images. Under general anesthesia, the antebrachiums of a total of sixteen rabbits of both sexes were scanned with a general diagnostic MDCT. Biometric measurements of the reconstructed...
