Article
Abstract A novel X-ray stereoscopy technique, using greyscale information obtained from moving markers, was used to study the 3D motion in both gerbil and rabbit middle ear ossicles in the quasi-static pressure regime. The motion can be measured without visually exposing the ossicles. The ossicles showed non-linear behaviour as a function of both p...

High-resolution 3D morphology models of cat, gerbil, rabbit, rat and human ossicular chains are presented. The models are based on high-resolution CT measurements. The resolution of the CT images, from which the models are segmented, varies from 5.6 to 33.5 μm. Models are freely available in different formats at our website (http://www.ua.ac.be/bim...

In order to improve realism in middle ear (ME) finite-element modeling (FEM), comprehensive and precise morphological data are needed. To date, micro-scale X-ray computed tomography (μCT) recordings have been used as geometric input data for FEM models of the ME ossicles. Previously, attempts were made to obtain these data on ME soft tissue structu...

We made a qualitative and quantitative comparison between a state-of-the-art implementation of micro-Computed Tomography (microCT) and the scanning Thin-Sheet Laser Imaging Microscopy (sTSLIM) method, applied to mouse cochleae. Both imaging methods are non-destructive and perform optical sectioning, respectively, with X-rays and laser light. MicroC...

We propose a new technique to measure the 3D motion of marker points along a straight path within an object using x-ray stereo projections. From recordings of two x-ray projections at different angles, the 3D coordinates of marker points can be determined. By synchronizing the x-ray exposure time to the motion event, a moving marker leaves a trace...
Article
Deformation of the tympanic membrane is known to contribute to the pressure regulation processes in the middle ear cleft. In this paper we investigated pressure variations in the rabbit middle ear in response to sinusoidal varying pressures applied to the ear canal, with frequencies ranging from 0.5 Hz to 50 Hz and pressure amplitudes ranging betwe...

The low-level laser irradiation at certain wavelengths is reported to facilitate the healing process of diabetic wounds. Thus, this study carried out to look for the suitable laser parameters that could speed up the healing process. Fourteen healthy male and female rats were used in which a circular wound with a diameter of 2.5 textpm 0.2 cm was cr...

The middle ear is a complex biomechanical impedance match between sound waves in air and in the fluid of the cochlea. Finite element modelling is a promising approach to study the behavior of this system. This method requires accurate and three-dimensional morphological data as input for its simulations. Till recently, no high-resolution and comple...
Thesis
Full-text available
The measurement of three-dimensional motion is important to study the mechanics of biological systems. For decades, efforts have been made to quantify and measure them using different approaches. X-ray stereoscopy as a technique was introduced one year after Roentgen discovered x-rays. The method is used to obtain 3D coordinates of marker points, a...

We propose a new technique to measure the 3D motion of marker points along a straight path within an object using x-ray stereo projections. From recordings of two x-ray projections with 90° separation angle, the 3D coordinates of marker points can be determined. By synchronizing the x-ray exposure time to the motion event, a moving marker leaves a...
Article
Full-text available
A method for high-resolution measurement of 3D coordinates and translations of small objects is presented, using single x-ray point-source stereoscopy. The theory of the pinhole method is re-derived for a point-source x-ray projection setup using a conical beam. The method is then implemented using a micro x-ray tomography setup with a single 8 mu...

In Sudan, X-rays are routinely used at least once for measurements of pelvis during the gestation period, though this is highly prohibited worldwide, except for a few life threatening cases. To demonstrate the effect of diagnostic ionizing radiation on uterus, fetus and neighboring tissues to the ovaries, two independent experiments on pregnant rab...
