Messenger Rna Profiling: A Prototype Method For Body Fluidand Tissue Identification
Conventional methods of body fluid identification use labor-intensive, technologically diverse techniques that are performed in a series, not parallel, manner and are costly in terms of time and sample. Furthermore, for some frequently encountered body fluids, such as saliva or vaginal secretions, …

A needle-tip embedded fibre optical force sensor for tissue identification
The identification of biological tissue types during needle insertion is subject to a lack of precise monitoring techniques, especially in an intensive magnetic resonance environment. One approach to improve this situation is to attach optical sensors to the surgical needle. In this research, a …

Electrical Impedance Spectroscopy with Multi-modal Tissue Discrimination for Ultrasound-Guided Targeted Biopsy
… electrical impedance spectroscopy to identify tissue at the needle tip in real-time, validated on an ex-vivo tissue dataset. Two data augmentation methods are proposed for improving classifiers trained on small datasets. Lastly, the thesis shows the ultrasonic vibrational potential can be …

Dynamic Discriminant Analysis with Applications in Computational Surgery
… include smart surgical tools for identifying tissues via backend sensing, and classifying surgical skill level using laparoscopic tool motion. Prior work in these fields has been impeded by the lack of a dynamic discriminant analysis technique capable of classifying data given systems with …

Identification of Saliva Using DNA Methylation Analysis for Forensic Use
<p>The identification of biological fluids is a precursor to determine if further human identification is required in a forensic setting. There are four forensically-relevant biological fluids: blood, semen, vaginal epithelial tissue, and saliva. While serological testing can identify these tissue …

High Resolution Melt Analysis of Samples with Differential DNA Methylation to Identify Tissue Source of Origin
… Science casework, identifying the source of a tissue can assist in crime scene reconstruction. Currently, presumptive testing methods to identify tissue type are utilized in crime scene laboratories, but there is a need for a more reliable confirmatory test for tissue type identification. High …

Development of X-ray Fan Beam Coded Aperture Diffraction Imaging for Improving Breast Cancer Diagnostics
… X-rays. While XRD measurements of human breast tissue have previously suggested differences between signatures of cancerous and benign tissues, the typical diffraction system architectures do not support fast, large field of view imaging that is necessary for medical applications.In this work, …
