Methods: Seven healthy adult mixed-breed pony mares were used in this study. Feed was withheld for 12 h prior to the WAC administration. After administration, a complete-feed diet was fed to allow the WAC to pass into the stomach. Lum...
Semi-autonomous wheelchair developed using a unique camera system configuration biologically inspired by equine vision. This paper is concerned with the design and development of a semi-autonomous wheelchair system using cameras in a system configuration modeled on the vision system of a horse. This new camera configuration utilizes stereoscopic vision for 3-Dimensional (3D) depth perception and mapping ahead of the wheelchair, combined with a spherical camera system for 360-degrees of monocular vision. This unique combination allows for static components of an unknown environment to be mapped and any surrounding dynamic obstacles to be detected, during real-time autonomous navigation, minimizing blind-spots an...

Coaxial illumination during viewing was provided by a single white light-emitting diode (LE...
Assessment of repeatability of a wireless, inertial sensor-based lameness evaluation system for horses. To determine repeatability of a wireless, inertial sensor-based lameness evaluation system in horses. Methods: 236 horses. Methods: Horses were from 2 to 29 years of age and of various breeds and lameness disposition. All horses were instrumented with a wireless, inertial sensor-based motion analysis system on the head (accelerometer), pelvis (midline croup region [accelerometer]), and right forelimb (gyroscope) before evaluation in 2 consecutive trials, approximately 5 minutes apart, as the horse was trotted in a straight line. Signal-processing algorithms generated overall trial asymmetry me...
Method to calibrate phase fluctuation in polarization-sensitive swept-source optical coherence tomography. We present a phase fluctuation calibration method for polarization-sensitive swept-source optical coherence tomography (PS-SS-OCT) using continuous polarization modulation. The method uses a low-voltage broadband polarization modulator driven by a synchronized sinusoidal burst waveform rather than an asynchronous waveform, together with the removal of the global phases of the measured Jones matrices by the use of matrix normalization. This makes it possible to average the measured Jones matrices to remove the artifact due to the speckle noise of the signal in the sample without introducing aux...
The use of computed tomographic three-dimensional reconstructions to develop instructional models for equine pelvic ultrasonography. Ultrasonography has gained increased utility to diagnose pelvic fractures in horses; however, internal pelvic contours can be difficult to appreciate from external palpable landmarks. We developed three-dimensional (3D) simulations of the pelvic ultrasonographic examination to assist with translation of pelvic contours into two-dimensional (2D) images. Contiguous 1mm transverse computed tomography (CT) images were acquired through an equine femur and hemipelvis using a single slice helical scanner. 3D surface models were created using a DICOM reader and imported into a 3D modeling and animatio...
Evidence-based medicine and stem cell therapy: how do we know such technologies are safe and efficacious? Evidence-based medicine (EBM) refers to the conscientious, explicit, and judicious use of current best evidence from research for the care of an individual patient. Central to the adoption of EBM is both producing and identifying the best possible evidence for a particular intervention or therapy. This article identifies and reviews the approaches to producing and identifying the best possible evidence that is necessary for the full acceptance of stem cell therapies in the horse and reviews the approaches that will allow future clinical studies in stem cell therapies to provide the best eviden...
Performance comparison between 8- and 14-bit-depth imaging in polarization-sensitive swept-source optical coherence tomography. Recently the effects of reduced bit-depth acquisition on swept-source optical coherence tomography (SS-OCT) image quality have been evaluated by using simulations and empirical studies, showing that image acquisition at 8-bit depth allows high system sensitivity with only a minimal drop in the signal-to-noise ratio compared to higher bit-depth systems. However, in these studies the 8-bit data is actually 12- or 14-bit ADC data numerically truncated to 8 bits. In practice, a native 8-bit ADC could actually possess a true bit resolution lower than this due to the electronic jitter in the convert...
Optic axis determination by fibre-based polarization-sensitive swept-source optical coherence tomography. We describe a fibre-based variable-incidence angle (VIA) polarization-sensitive swept-source optical coherence tomography (PS-SS-OCT) system to determine the 3D optical axis of birefringent biological tissues. Single-plane VIA-PS-OCT is also explored which requires measurement of the absolute fast-axis orientation. A state-of-the-art PS-SS-OCT system with some improvements both in hardware and software was used to determine the apparent optical birefringence of equine tendon for a number of different illumination directions. Polar and azimuthal angles of cut equine tendon were produced by the ...
Validation and usefulness of the Sperm Quality Analyzer V equine for equine semen analysis. Routine semen analysis includes evaluation of concentration combined with seminal volume, morphology and motility. Subjective analysis of these parameters is known to be inaccurate, imprecise and subject to variability. Automated semen analysis could lead to an increased standardization in and between laboratories but for that to happen automated devices need to be validated. A new device, the sperm quality analyzer V equine (SQA-Ve) version 1.00.43, was evaluated for its repeatability and agreement with light microscopy (LM), for raw and extended equine semen. Results were compared with compu...
A linear laser scanner to measure cross-sectional shape and area of biological specimens during mechanical testing. Measure of the cross-sectional area (CSA) of biological specimens is a primary concern for many biomechanical tests. Different procedures are presented in literature but besides the fact that noncontact techniques are required during mechanical testing, most of these procedures lack accuracy or speed. Moreover, they often require a precise positioning of the specimen, which is not always feasible, and do not enable the measure of the same section during tension. The objective of this study was to design a noncontact, fast, and accurate device capable of acquiring CSA of specimens mounted on a ...
The use of a simple backflush technology to improve sample throughput and system robustness in routine gas chromatography tandem mass spectrometry analysis of doping control samples.

Part B: Seventy-eight hours of audio...
Design of a multifaceted referral equine hospital. There is no simple recipe for designing a multifaceted practice. However, keys to any design are the devotion of the people involved and proper positioning of such people in the organization. Anyone designing such a practice also must pay keen attention to details and a keep a finger constantly on the pulse of the business to ensure that it maintains a sound financial footing and a consistent vision. Little money is made from savings or pushing financials. Profits come mainly through building additional sales, maintaining a clear vision, and making shrewd investments. Like for every small busi...
Dynamic respiratory endoscopy in 67 Thoroughbred racehorses training under normal ridden exercise conditions. There are potential advantages to imaging the upper portion of the respiratory tract (URT) of horses during ridden exercise. With the advent of a wireless endoscope, this is now possible. However, there has been no detailed validation of the technique and findings have not been compared to ridden speed. Objective: To assess the combined use of a Dynamic Respiratory Scope (DRS) and global positioning system (GPS) receiver for examining the URT of a group of Thoroughbred racehorses randomly selected from a single flat racehorse training establishment. Methods: Horses were selected randomly from ...
Alternative solution of virtual biomodeling based on CT-scans. In this paper, an alternative method is presented to convert computed tomography (CT)-scans into 3D biomodels. The CT-data of an equine spine was converted into TIF format to work with it in a 2D CAD program. Then the bony structure has been marked manually with closed splines and saved as IGS files for the next procedure with 3D CAD software to create virtual biomodels of every single bone. Therefore, the different layers of the CT-scans were positioned in correct distance and then a closed surface was created to cover all spline-curves. Finally, the cover was filled up with material to creat...
Clinical trials using a telemetric endoscope for use during over-ground exercise: a preliminary study. Dynamic collapse of the upper respiratory tract (URT) is a common cause of poor performance in horses. These conditions occur predominantly during strenuous exercise when the URT is unable to maintain dilation in the face of high inspiratory pressures. In most cases, these disorders cannot be accurately diagnosed during a resting endoscopic examination. To date, a definitive diagnosis of dynamic URT obstructions has been possible only by performing an endoscopic examination during high-speed treadmill exercise. However, recent technological advances now enable URT endoscopy to be performed whi...

Virtual histology by means of high-resolution X-ray CT. Micro-CT is a non-destructive technique for 3D tomographic investigation of an object. A 3D representation of the internal structure is calculated based on a series of X-ray radiographs taken from different angles. The spatial resolution of current laboratory-used micro-CT systems has come down over the last years from a few tens of microns to a few microns. This opens the possibility to perform histological investigations in 3D on a virtual representation of a sample, referred to as virtual 3D histology. The advantage of micro-CT based virtual histology is the immediate and automated 3D visua...
Less invasive techniques for equine fracture repair and arthrodesis. To repair equine fractures successfully, surgeons traditionally have done aggressive open approaches with maximal internal fixation to achieve adequate stability and comfort. Although the need for stability is unquestionable, newer technologies and imaging modalities have allowed improvement in the biology of internal fixation in selected fractures and arthrodeses.
