Objective . To compare the in vitro reliability and accuracy of linear measurements between cephalometric landmarks on CBCT 3D images with varying basis projection images to direct measurements on human skulls. Methods . Sixteen linear dimensions...
The purpose of this project was to compare the accuracy and reliability of linear measurements made on 2D projections and 3D reconstructions using Dolphin 3D software (Chatsworth, CA) as compared to direct measurements made on human skulls. The...
A blinded observational cross-sectional in vitro study was conducted to compare the diagnostic accuracy of observers viewing images made using cone beam computerized tomography (CBCT), panoramic radiography and linear tomography. The sample...

CBCT in endodontics demonstrates anatomic features in 3D that intraoral, panoramic, and cephalometric images cannot. CBCT units reconstruct the projection data to provide interrelational images in three orthogonal planes (axial, sagittal, and...
Computer-aided minimally invasive surgery (MIS) has progressed significantly in the last decade and it has great potential in surgical planning and operations. To limit the damage to nearby healthy tissue, accurate modeling is required of the...
The aim of the study was to determine the incidence and imaging characteristics of soft tissue calcifications on cone beam computed tomography (CBCT). 556 CBCT image datasets were reviewed and 308 included. The following conditions were recorded:...
Respiratory syncytial virus is the leading cause of lower respiratory tract infection
in infants and currently lacks an effective vaccine or treatment beyond symptom relief.
The atomic force microscope is particularly well suited for imaging...
Purpose: To evaluate baseline and 3 different image enhancements for the detection of landmarks and overall perceived quality in photostimuable phosphor cephalograms. Methods: DenOptix images of 48 patients (plus 12 repeats) were presented randomly...
From a computerized image analysis prospective, early diagnosis of lung cancer involves detection of doubtful nodules and classification into different pathologies. The detection stage involves a detection approach, usually by template matching,...
The aim of the research is to determine if cone beam computerized tomography reconstructed panoramic radiography viewed in two different focal trough shapes, and three different focal trough widths changes the ability to identify high risk...
Three-dimensional imaging in medicine; Lungs--Cancer--Diagnosis
Many lung diseases or injuries can cause biomechanical or material property changes that can alter
lung function. While the mechanical changes associated with the change of the material properties
originate at a regional level, they remain largely...
Potential dental implant site assessment is initially determined clinically. Subsequent radiographic assessment also provides information about the quantity of available bone. It was hypothesized that the use of radiographic markers in mandibular...
The past decade has brought about major advances in the realms of both
healthcare and biometrics. New technologies and techniques in the field of biometrics
has allowed for the quick and efficient identification of people, while new...
Introduction: The study investigated dimensional relationships between the sphenoid and maxillary sinuses and other selected craniomaxillofacial structures by using traditional cephalometric and volumetric procedures based on cone beam computed...

Gold nanoparticles (GNPs) have shown beneficial properties for biomedical use, e.g., their non-toxic nature and surface properties for easy modification. Upon receiving light, they generate a strong surface plasmon field, which can alter the...
The use of monochloramines in the potable water supply industry has been selected as the disinfectant method of choice due to a longer term of effectiveness and less toxic by-products than the previous choice of chlorine. In spite of the benefits...
Blood flow--Measurement; Magnetic resonance imaging
Peripheral Arterial Disease (PAD) is a progressive atherosclerotic disorder which
is defined as any pathologic process obstructing the blood flow of the arteries supplying
the lower extremities. Moderate stenoses mayor may not be...
Various vision tasks are usually confronted by appearance variations due to changes of illumination. For instance, in a recognition system, it has been shown that the variability in human face appearance is owed to changes to lighting conditions...
Nanoscience is not about products becoming smaller and smaller, but about new material properties being exploited for new and enhanced product applications. Liquid crystalline materials are one branch of "nanomaterials" that has promise...
