3D approximation of scapula bone shape from 2D X-ray images using landmark-constrained statistical shape model fitting

Author: Wasswa, William Date: 2016 Two-dimensional X-ray imaging is the dominant imaging modality in low-resource countries despite the existence of three-dimensional (3D) imaging modalities. This is because fewer hospitals in low-resource countries can afford the 3D imaging ... Read more
Autofocusing and image segmentation in microscopy for automatic detection of tuberculosis in sputum smears

Author: Russell, Megan J Date: 2006 The World Health Organisation (WHO) has declared that tuberculosis (TB) is a global emergency. With the common combination of TB and AIDS in sub-Saharan Africa, the number of people dying from TB has increased enormously (WHO, 1996). The smart ... Read more
Characterization of the facial phenotype associated with fetal alcohol syndrome using stereo-photogrammetry and geometric morphometrics

Author: Mutsvangwa, Tinashe E M Date: 2009 Fetal Alcohol Syndrome (FAS) is a clinical condition caused by excessive pre-natal alcohol exposure and is regarded as a leading identifiable and preventable cause of mental retardation in the Western world. The highest prevalence of FAS was ... Read more
A comparison of methods for the registration of tractographic fibre images

Author: Golding, Dan Date: 2011 Diffusion tensor imaging (DTI) and tractography have opened up new avenues in neuroscience and are allowing previously unexplored areas of neuroanatomy and function to be researched. Read more
Computer models for the design and optimization of a linear slot scanning mammography system

Author: Hussein, Khalid Ibrahim Date: 2008 Includes abstract. Includes bibliographical references (p. 143-151). Read more
Computer-aided diagnosis of tuberculosis in paediatric chest X-rays using local textural analysis

Author: Mouton, Andre Date: 2009 This report presents a computerised tool to analyse the appearance of the lung fields in paediatric chest X-rays to detect the presence of tuberculosis. The computer aided diagnosis (CAD) tool consists of 4 phases: 1) lung field segmentation; ... Read more
Creating a virtual slide map from sputum smear images for region-of-interest localisation in automated microscopy

Author: Patel, Bhavin Date: 2010 Automated microscopy for the detection of tuberculosis (TB) in sputum smears seeks to address the strain on technicians in busy TB laboratories and to achieve faster diagnosis in countries with a heavy TB burden. As a step in the development ... Read more
Development of an assessment framework for student engagement in design thinking projects for health innovation

Author: Dikgomo, Kagiso Date: 2020 Student engagement is a dynamic and multifaceted concept – it encompasses physical, emotional, and cognitive components. Various instruments to assess student engagement exist, however these are not intended to assess how students engage with ... Read more
Evaluating the usability of an X-ray imaging system in forensic pathology

Author: Mutswangwa, Christopher T Date: 2018 Post mortem imaging (PMI) is increasingly being adopted as an alternative to invasive autopsies in forensic pathology. PMI can be used as a sole technique or adjunct to an autopsy. The Lodox Xmplar-dr is an X-ray imaging system that has been ... Read more
Hardware and software integration and testing for the automation of bright-field microscopy for tuberculosis detection

Author: Sarala, Devi Krishna Date: 2011 Automated microscopy for the detection of tuberculosis (TB) in sputum smears would reduce the load on technicians, especially in countries with a high TB burden. This dissertation reports on the development and testing of an automated system ... Read more
Image segmentation and object classification for automatic detection of tuberculosis in sputum smears

Author: Khutlang, Rethabile Date: 2009 An automated microscope is being developed in the MRC/UCT Medical Imaging Research Unit at the University of Cape Town in an effort to ease the workload of laboratory technicians screening sputum smears for tuberculosis (TB), in order to ... Read more
The impact of mHealth interventions on health systems: a systematic review protocol

Author: Fortuin, Jill ; Salie, Faatiema ; Abdullahi, Leila H ; Douglas, Tania S Date: 25 Nov 2016 Background: Mobile health (mHealth) has been described as a health enabling tool that impacts positively on the health system in terms of improved access, quality and cost of health care. The proposed systematic review will examine the impact ... Read more c b
Implementation and evaluation of a bony structure suppression software tool for chest X-ray imaging

Author: Dixon, Toinette-Lee Date: 2012 This project proposed to implement a bony structure suppression tool and analyse its effects on a texture-based classification algorithm in order to assist in the analysis of chest X-ray images. The diagnosis of pulmonary tuberculosis (TB) ... Read more
Interlandmark measurements from lodox statscan images with application to femoral neck anteversion assessment

Author: Chimhundu, Chipo Date: 2013 Clinicians often take measurements between anatomical landmarks on X-ray radiographs for diagnosis and treatment planning, for example in orthopaedics and orthodontics. X-ray images, however, overlap three-dimensional internal structures onto ... Read more
An investigation into the use of stereophotogrammetry for the analysis of craniofacial dysmorphology in schizophrenia

Author: Cousins, Michael Date: 2015 Studies of craniofacial dysmorphology in schizophrenia, carried out since the 1960s, have reported minor physical anomalies in those with schizophrenia, prominently in the craniofacial region. Indirect methods, most notably 3D laser imaging, ... Read more
Investigation of differences in cortical activation during wrist flexion and extension performed under real, passive and motor imagined paradigms

Author: Stoeckigt, Stefan Date: 2016 The neuromuscular control comparison between flexion and extension of the upper extremities has been conducted in a number of studies. It has been speculated that differences in the corticospinal pathway between flexion and extension may play ... Read more
Issues in the processing and analysis of functional NIRS imaging and a contrast with fMRI findings in a study of sensorimotor deactivation and connectivity

Author: Robertson, Frances Date: 2012 The first part of this thesis examines issues in the processing and analysis of continuous wave functional linear infrared spectroscopy (fNIRS) of the brain usung the DYNOT system. In the second part, the same sensorimotor experiment is carried ... Read more
Localising discrete points in 3D space using stereo pairs of digital slot-scanning X-rays

Author: Wynne, Susan M Date: 2006 Includes bibliographical references (p. 104-111). Read more
Locating regions of interest prior to X-ray imaging using stereo-photogrammetry

Author: Kulkarni, Radhika Date: 2011 The research project aims at locating regions of interest (ROIs) on human subjects prior to X-ray imaging on the Lodox Statscan whole body imaging system. Read more
