Fall 2020
This thesis describes the research and development process in creating a 3D ultrasound-based navigation system to assist screw insertion for scoliosis surgery, with a focus on children who have adolescent idiopathic scoliosis (AIS). Screw placement accuracy is critical to prevent spinal cord or...

A Comparison Study of the Reliability Coefficients from Five Approaches to Reliability Estimation
DownloadFall 2015
In order to estimate reliability by a single administration of one test form, various approaches and corresponding reliability coefficients have been proposed so far. Currently, the five most influential approaches are: internal consistency, lower bound, principal components analysis (PCA),...

A Novel 3D Printed Brace Manufacturing Process for the Treatment of Adolescent Idiopathic Scoliosis
DownloadSpring 2019
Adolescent Idiopathic Scoliosis (AIS) is a three-dimensional spinal deformity with lateral curvature and axial vertebral rotation affecting 1-3% of adolescents. Bracing is a proven non-surgical treatment aiming to stop curve progression. Literature has shown that brace wear time affects brace...

Accuracy and reliability of CBCT imaging for adenoid hypertrophy screening among a sample of oral maxillofacial radiologists and orthodontists and by an automated commercial imaging software
DownloadSpring 2016
Objectives. This thesis project aimed to investigate the diagnostic performance of different dental specialists and a modern dental imaging software to evaluate adenoidal hypertrophy compared with the current reference standard diagnosis by an Otorhinolaryngologist – Head and Neck Surgeon (OHNS)...

Algorithms for Adolescent Idiopathic Scoliosis Classification Based on Surface Topography Analysis
DownloadSpring 2018
While the common method for diagnosing and monitoring adolescents with idiopathic scoliosis (AIS) is X-ray radiographs from which a Cobb angle is measured, studies have shown that high radiation exposure is linked to high risk of cancer, particularly, for children and women. This thesis describes...

Hernandez Peralta, Rodrigo Arturo
The objective of this research was to examine the cold temperature limitation of the elastomeric material currently used in railcar airbrake glad-hand gaskets. A test plan to assess gasket material performance was designed based on gasket operating conditions and material properties. Standards,...

Application of a biomechanical finite element spine model to the vicious cycle scoliosis growth theory: evaluation of improved FEA geometry and material assignment
DownloadFall 2009
Scoliosis is defined as the abnormal three dimensional curvature of the spine with 80% of all cases being idiopathic in nature. If left unchecked, this condition can cause cardio-pulmonary complications and occasionally death. Currently, the most common method of treatment of scoliosis is through...
