Development Of A Mammographic Image Processing Environment Using Matlab, John L. Kelley

Theses and Dissertations

Breast cancer is a disease that accounts for a disturbingly large number of deaths in females each year. Its prevalence is a topic of concern to all of us since it can affect our families, friends, and coworkers. Although mammographic screening is the most effective method currently available for the early detection of breast cancer, it is far from being an infallible procedure. Mammographic reading is error prone, partly because of the complexity of the task and partly because of the variability in human performance. Computers offer high reproducibility, and when used as an adjunct by the radiologist, may improve …

Prevalence Of Fatty Liver In Japanese Children Ages 4 To 12 Years Old : Relationship To Obesity : An Epidemiological Ultrasonographic Survey, Kunihiko Tominaga

Loma Linda University Electronic Theses, Dissertations & Projects

The prevalence of fatty liver disease in children is not well established and its relationship to childhood obesity is poorly defined. The present study of 810 northern Japanese school-aged children (4-12 years old), determined the prevalence of fatty liver and its relationship to gender and degree of obesity. Diagnosis of fatty liver was assessed by real-time ultrasonography.

RESULTS: 1. The overall prevalence of fatty liver is 2.6 %. 2. Fatty liver prevalence is higher for boys (3.4 %) than for girls (1.8 %), although not statistically significant (P = 0.15). 3. Fatty liver occurs in children as young as 6 …

Reducing Respiratory Artifacts In Chest Mr Images Through Hybrid Space Motion Tracking And Postprocessing, John N. Campbell, Wesley E. Snyder, Peter Santago Ii, Sarah A. Rajala, Craig A. Hamilton

Sarah A. Rajala

A new postprocessing method of correcting for respiratory motion induced artifacts in MRI is presented. The motion of the chest during respiration is modeled as a combination of translation and dilation. Displacements of the chest wall are tracked via a thin, MR-sensitive plate placed on the patient's chest during a scan. Scanning with phase encoding left/right (L/R) and frequency encoding anterior/posterior (A/P) causes the motion artifacts to be repeated in the L/R direction, thus not overlapping on the plate. By performing the inverse A/P Fourier transform, the resulting hybrid space data has A/P spatial data and L/R spatial frequency data, …
