Colorectal Cancer Screening: A Non-Invasive Approach
<p>COLORECTAL CANCER SCREENING: A NON-INVASIVE APPROACH Amy Frazier May, 2004 58 Pages Directed by: Dr. Donna Blackburn, Dr. Patricia Bailey, and Dr. Thomas Nicholson Department of Nursing Western Kentucky University Colorectal cancer (CRC) is the third most common malignant neoplasm worldwide and …

Non-Invasive Intracranial Pressure Method and Monitor
The eyes are acoustically continuous with the brain and inner ear tissues in regard to matched impedances, based on tissue densities, thus, vibration of one site will be reflected in all sites. With this being the case, the vibrational energy response of the eye due to an external source can be …

Non-invasive in vivo ultrasound temperature estimation
… (HIFU) has emerged as a promising modality for noninvasive surgery due to its ability to create precise mechanical and thermal effects at the target without affecting surrounding tissues. An essential element in all these procedures, however, is accurate estimation of the target tissue …

Non-invasive IC tomography using spatial correlations
… The proposed methodology is fast, inexpensive, non-invasive, and applicable to legacy designs. Noninvasive IC characterization has a range of emerging applications, including post-silicon optimization, IC identification, and variations' modeling/simulations. The evaluation results on standard …

Landfill design, construction and non-invasive monitoring
Three techniques are investigated in order to assess their applicability for use in landfill design, construction and monitoring. Firstly, an assessment is made of QA procedures during liner construction through the detailed evaluation of two case studies. Construction QA procedures on-site are …

Non-invasive diagnostic methods of intracranial arteries
… to evaluate the diagnostic accuracy of CTA in non-traumatic subarachnoid haemorrhage (SAH) compared to DSA and to assess the arterial attenuation (HU) as an image quality factor in this aspect. Follow-up DSA and time-of-flight (TOF) MRA at 1.5T and 3T as well as contrast-enhanced MRA at 3T were …

Translational Modeling of Non-Invasive Electrical Stimulation
… 2000’s demonstrated the effect of low amplitude non-invasive electrical stimulation in people using neurophysiological measures (motor evoked potentials, MEPs). Clinical applications of transcranial Direct Current Stimulation (tDCS) have since proliferated, though the mechanisms are not fully …

Non-invasive early diagnosis of deep vein thrombosis
… Embolism (PE). DVT can be diagnosed using non-invasive technique such as ultrasonography. One of the factors that cause the deep vein thrombosis occurs is the behaviour of vein valve. Therefore, the movement of vein valve needs to track to make further analysis of its behaviour for early …

Tissue Oxygen Imaging for Non-invasive Metastasis Detection
… and reduces the patient’s quality of life. Non-invasive metastasis detection is also used clinically but these detection methods lack high sensitivity for small metastases. Higher sensitivity detection techniques enable earlier treatment which may improve survival rates. With recent evidence …

NON INVASIVE CANCER DETECTION: FROM BENCH TO BEDSIDE
… gold standard cancer diagnosing procedures were invasive and expensive. Mass screening for cancer could save a lot of lives. The diagnostic procedure should be non-invasive, low-cost and easy to use to implement mass screening. This thesis investigated the possible non-invasive modalities of …

Non-invasive monitoring of bone health using ultrasound
… Ultrasound can monitor bone fractures in a non-invasive manner, as discussed in United States Patent # 5143069. Three transducers are mounted over the test specimen. A pulse generator excites the transmitting receiver. The second receiver is mounted next to the transmitter and acts as a …

Non-invasive interventions top reduce low back dysfunction
This study aims to quantitatively evaluate the low back condition so that low back dysfunction can be identified and classified when measurements show a variance from the normal. The evaluation is done by using the hysteresis concept. In this study, subjects received two different types of …

A European survey of Non- Invasive Ventilation (NIV)
Although non-invasive ventilation (NIV) is becoming very popular, little is known about its pattern of clinical and technical utilization in the different environments. We conducted a web-based survey in Europe to identify the perceived pattern of NIV utilization and the reason for choosing a …

Latent feature models and non-invasive clonal reconstruction
… The second type, instead, generally comprises non-parametric mixture models, with strict assumptions on the tumour’s evolutionary process. The focus of this dissertation is on the development of a phylogenetic latent feature model that can bridge the advantages of these two approaches, allowing …

A mobile platform for non-invasive diabetes screening
The global burden of diabetes is profound, with over 400 million cases worldwide. Middle-income countries, such as those in Southeast Asia, are especially affected as diabetes becomes a major public health issue. In particular, India has a record number of people diagnosed with diabetes, 8.8% of …

Non-invasive system identification of a tactical generator
… providing power are needed. In this thesis, non-invasive experimental methods for determining synchronous machine system parameters for a Tactical Quiet Generator (TQG), a generator commonly used by the US military, are explored. While the generator's rotor is at standstill, direct voltage …
