Stereology applied on histological sections is the 'gold standard' for obtaining quantitative information on cancellous bone structure. Recent advances in micro computed tomography (microCT) have made…
The diagnosis of myoepithelial sialadenitis (MESA) in fine needle aspiration biopsy may be difficult. There is a dense lymphocytic infiltration in the gland and discrimination between a hyperimmune re…
The nonprewhitening matched filter (NPWMF) was used to study the effect of wavelet-based lossy image compression on lesion detectability. Two classes of images, representing lesion-present and lesion-…
Helical CT is being increasingly used for the evaluation of suspected tracheal diseases. Although nonneoplastic and noninfectious diseases of the trachea are rare, their appearance on CT images may be…
The best method of training for laparoscopic surgical skills is controversial. Some advocate observation in the operating room, while others promote animal and simulated models or a combination of sur…
The micronucleus assay in human lymphocytes is, at present, frequently used to assess chromosomal damage caused by ionizing radiation or mutagens. Manual scoring of micronuclei (MN) by trained personn…
A method is described to determine the total retinal blood flow. Intravenous fluorescence angiography is the clinical procedure used, together with digital image processing methods. Our system consist…
PURPOSE: To validate the 2010 diagnostic criteria from the American Association for the Study of Liver Diseases (AASLD) for hepatocellular carcinoma (HCC) on MRI using the surgical liver specimen as a…
Evaluation of the cytoskeleton mechanical properties requires specific micromanipulation techniques such as the magnetic twisting cytometry technique, in which microbeads are specifically linked to th…
G8 is a benchtop integrated PET/CT scanner dedicated to high-sensitivity and high-resolution imaging of mice. This work characterizes its National Electrical Manufacturers Association NU 4-2008 perfor…
We studied the free gait of children by analyzing the wave pattern of the ground reaction force (GRF) and measuring time and distance parameters using large force plates. Two hundred and forty-one nor…
In October 1988, right-to-know legislation was introduced in Canada. This presented a technical and administrative challenge to the health care sector. With over 170 health care facilities in Manitoba…
PURPOSE: The Varian Halcyon™ electronic portal imaging detector is always in-line with the beam and automatically acquires transit images for every patient with full-field coverage. These images could…
OBJECTIVE: To develop a novel framework for evaluating the accuracy of quantitative analysis on dynamic contrast-enhanced (DCE) MRI with a specific combination of imaging technique, scanning parameter…
This study assessed the repeatability of the Nikon NRK-8000, the Nidek KM-800 and the Bausch and Lomb keratometer. In addition, the comparability of the Nikon NRK-8000 and the Nidek KM-800 are evaluat…
BACKGROUND: Use of rapidly emerging real-time 3-dimensional (3D) echocardiography promises to improve the diagnostic accuracy of stress echocardiography (SE). However, widespread acceptance of 3D-SE, …
OBJECTIVE: Minimally invasive surgery offers advantages for management of obese patients, but technical difficulty often deters its utilization. Compared to laparotomy, robotic surgery should allow co…
Source localization using the steered response power (SRP) usually requires a costly grid-search procedure. To address this issue, a modified SRP algorithm was recently introduced, providing improved …
In 1994, countries in the Region of the Americas adopted the goal of eliminating endemic measles transmission in the Western hemisphere by 2000. Since 1994, rapid progress has been made. The number of…
PURPOSE: For some time, the ambulatory diagnosis of sleep-related breathing disorders has included the use of seven-channel recording units. One such unit is the POLY-MESAM (MAP, Martinsried, FRG). Th…
