Prostate cancer recognition in ultrasound images
… via computer automated analysis of prostatic ultrasound imagery. Absorption of ultrasound signals is different in cancerous areas than in non-cancerous areas. The energy of the signal, the continuity of the signal, the autocorrelation function and frequency domain properties of prostatic …

Quantitative Analysis of Ultrasound Images of the Preterm Brain
… white matter damage in the preterm Brain. Since Ultrasound imaging is the most suited modality for the inspection of brain pathologies in very low birth weight infants we propose multiple techniques to assist in what is called Computer-Aided Diagnosis. As a main result we are able to increase the …

Contrast enhancement of ultrasound images using shunting inhibitory cellular neural networks
… (SICNN) to solve the clarity problems in ultrasound imaging. In this thesis, we begin by reviewing a number of traditional enhancement techniques and measures. Since the entire work of this thesis is based upon a particular model of the CNN, we present a brief review of CNN theory and its …

Feature detection in ultrasound images for computer aided diagnosis of Hodgkin's Lymphoma
… improving diagnostic imaging interpretability of ultrasound for HL diagnosis in a HIV TB endemic environment. To achieve this, a precise abdominal ultrasound protocol was developed with clinical guidance. The specific frames in the protocol were used to detect several image biomarkers of clinical …

Thickness estimation, automated classification and novelty detection in ultrasound images of the plantar fascia tissues
… cause injuries and some severe common diseases. Ultrasound (US) imaging offers significant potential in diagnosis of PF injuries and monitoring treatments. Despite the advantages of US, the generated PF images are difficult to interpret during medical assessment. This is partly due to the size …

MITIGATING DATA SCARCITY CHALLENGES IN MEDICAL IMAGING ANALYSIS:ADVANCED LEARNING APPROACHES WITH EMPHASIS ON HEMOPHILIC ULTRASOUND IMAGES
… in assessing joint health and bleeding events. Ultrasound (US) imaging is a fundamental tool in the diagnostic process and is currently used to identify when the joint recess is filled with synovial fluid or blood, a condition known as “recess distention” that, if filled with blood, can …

Detection of muscle damage by B-mode ultrasonography : relationship between echo intensity and histological changes following injection of bupivacaine to rat hind limb muscles
It is reported that the echo intensity of B-mode ultrasound images increases when human elbow flexors are damaged by eccentric exercise. However, it is unknown what causes the increase in echo intensity, and its relationship to histological changes is unexplored. This study tests the hypothesis …

The design, construction and testing of a hermetically sealed breast platfrom for dual-modality mammography
When ultrasound is used as an adjunct to X-ray mammography in either hand-held or automated mode, the patient typically lies in a prone position. The disadvantages of this approach include: variable image quality; poor co-registration of X-ray and ultrasound images; and increased costs and patient …
