Miniature Optical Coherence Tomography Probe
(Biomedical Engineering, 2007-08-23)
A piezo based optical scanner for high speed optical coherence tomography (OCT) has been developed. Design of the miniature probe has been optimized to take advantages of the high speed depth scanning that can be achieved ...
Magnetically Anchored "reduced Trocar" Laparoscopy: Evolution Of Surgical Robotics
(Biomedical Engineering, 2007-08-23)
Laparoscopic surgery has become increasingly popular over the last few years due to its benefits; lower morbidity, less perceived pain, better cosmesis results, and less hospital time. For the surgeon however, there are ...
Spectroscopic Characterization Of Biliary Tract Tissues In-vivo To Assist Laparoscopic Cholecystectomy
(Biomedical Engineering, 2007-08-23)
Laparoscopic Cholecystectomy is a surgical method for removal of gallbladder when it is diseased with gall stones. Almost 750,000 people are affected with this disease annually in USA. Gall bladder is removed by placing ...
Spatial Resolution And Biliary Tissue Classification Properties Of A Near Infrared Light Imaging Probe
(Biomedical Engineering, 2007-10-08)
Approximately 500,000 Gallbladder Surgeries or Laparoscopic Cholecystectomies are performed annually to remove the Gallbladder. This surgery becomes necessary due to formation of gall stones. As biliary tract tissues are ...
Characterization And Feasibility Study Of A Near Infrared CCD Imager For Monitoring Tumor Hemodynamics
(Biomedical Engineering, 2007-08-23)
Prostate cancer is one of the most common types of cancers diagnosed among North American men. Chemotherapy is generally used to target advanced metastatic prostate cancer. Near infrared spectroscopy (NIRS) has been ...
Investigation Of Brain Activities Using Two State-of-the-art Diffuse Optical Imagers
(Biomedical Engineering, 2007-09-17)
Near-Infrared Spectroscopy (NIRS) and diffuse optical imaging (DOI) are increasingly used to detect hemodynamic changes in the cerebral cortex induced by brain activity. The new commercially available DOI systems CW5 and ...
Use Of Near Infrared And Visible Spectroscopies To Determine Optical Properties Of Rat Nervous System
(Biomedical Engineering, 2007-08-23)
Changes to the anatomical or physiological structure of the neuronal circuitry are known to produce a change in the optical properties of the tissue under investigation. The goal of this thesis is to determine changes in ...
Fiber Based Non-linear Excitation Fluorescence Microscopy
(Biomedical Engineering, 2007-08-23)
Non-linear excitation fluorescence microscopy is a high resolution, non-invasive biological imaging technique capable of imaging both in vitro and in vivo at the depths of several hundred microns. The goal of the thesis ...
Near Infrared Spectroscopy: A Study Of Cerebral Hemodynamics During Breathholding And Development Of A System For Hot Flash Measurement
(Biomedical Engineering, 2007-08-23)
Near Infrared (NIR) spectroscopy and imaging has become popular in research fields for the past 2-3 decades. My research focuses on the continuous wave near infrared imaging technique. The work consists of two main parts. ...
A Comprehensive Study Of The Effects Of EEG Electrode Arrays On MRI Signal-to-noise At 3T
(Biomedical Engineering, 2007-09-17)
Simultaneous EEG-fMRI offers much potential for gaining complementary, noninvasive information about brain function. While much effort has been devoted to the compelling problem of removing ballistocardiogram and gradient ...
