Three-Dimensional Ultrasound Imaging For Blood Flow Assessment In First Carpometacarpal Osteoarthritis
… thesis reports on an investigation of the use of three-dimensional (3D) Doppler ultrasound (US) blood flow imaging and an assessment of the reliability of 3D US joint blood flow measures in CMC1 OA patients. Five healthy volunteers had 3D US imaging of their thumbs submerged in a water solution at …

The Role of Three-dimensional Ultrasound in the Diagnosis and Treatment of Uterine Pathology
This thesis investigated the role of three – dimensional transvaginal ultrasound in the identification, classification and management of uterine pathology. We performed serial measurements of fibroids over a period of time to examine their natural history. We found that fibroids tend to grow at a …

Corrélation of Plasma Osteopontin Levels and 3D US Imaging with Tumor Response to Neoadjuvant Therapy
… of plasma osteopontin (OPN) levels and three dimensional ultrasound imaging (3D US). Using our laboratory’s in house ELISA, we found that 39% of LABC patients had plasma OPN levels elevated above the normal healthy range of I23ng/ml (Bramwell,20o6). Over treatment this percent increased, …

Ultrasound probe localization by tracking skin features
Ultrasound probe localization with respect to the human body is essential for freehand three-dimensional ultrasound (3D US), image-guided surgery, and longitudinal studies. Existing methods for probe localization, however, typically involve bulky and expensive equipment, and suffer from patient …

Deformation correction in ultrasound imaging in an elastography framework
Tissue deformation in ultrasound imaging is an inevitable phenomenon and poses challenges to the development of many techniques related to ultrasound image registration, including multimodal image fusion, freehand three-dimensional ultrasound, and quantitative measurement of tissue geometry. In …

Development and Validation of Mechatronic Systems for Image-Guided Needle Interventions and Point-of-Care Breast Cancer Screening with Ultrasound (2D and 3D) and Positron Emission Mammography
… needle interventions. Specifically, 2D and 3D ultrasound (US) and positron emission mammography (PEM) were employed to improve detection, independent of breast density, in conjunction with mechatronic and automated approaches for accurate image acquisition and precise interventional workflow. …

A Novel System and Image Processing for Improving 3D Ultrasound-guided Interventional Cancer Procedures
… objective of this thesis was to incorporate 3D ultrasound (US) imaging and image processing methods during image-guided cancer interventions in the prostate and liver to provide accessible, fast, and accurate approaches for clinical improvements. An automatic 2D-3D transrectal ultrasound (TRUS) …

Ultrasound prediction of large fetuses. Epidemiological and clinical investigations
… (LGA) term newborns by using a routine fetal two-dimensional (2D) ultrasound examination for fetal growth in the third trimester of pregnancy, and to examine whether the detection rate could be further improved by including maternal pre-pregnancy and pregnancy-related variables to the estimated …
