Optical Pulling, Optical Deflection, and Optical Trapping of Single Airborne Particles using Negative Photophoresis
(East Carolina University, 2016-05-03)
Optical manipulation is the use of light to control the motion of objects. This thesis focuses on the development of optical transportation technology via optical pulling with application to the characterization of single ...
DOSIMETRIC STUDY OF BETA-MINUS EMITTER PRASEODYMIUM-142 : APPLICATIONS IN MICROSPHERE BRACHYTHERAPY FOR HEPATOCELLULAR CARCINOMA AND BRACHYTHERAPY FOR OCULAR SQUAMOUS CELL CARCINOMA
(East Carolina University, 2013)
A dosimetric study of the beta-minus emitter Praseodymium-142 (¹⁴²Pr) was performed and two main innovative applications of this source in brachytherapy are proposed: microsphere brachytherapy and eye plaque brachytherapy. ...
Correlating the Morphological and Light Scattering Properties of Biological Cells
(East Carolina University, 2013)
The scattered light pattern from a biological cell is greatly influenced by the internal structure and optical properties of the cell. This research project examines the relationships between the morphological and scattering ...
A PROPOSED METHODOLOGY TO ASSESS HDR [superscript]192Ir RADIAL DOSE WITH FRICKE DOSIMETRY
(East Carolina University, 2011)
The radial absorbed dose to water, D(r,theta), a quantity not yet directly measured with primary standards, was assessed with the Fricke solution which has been considered as an absolute aqueous solution to perform dosimetry. ...
Flow cytometer apparatus for three dimensional difraction imaging and related methods
(2015-04-21)
A flow cytometer assembly includes a fluid controller configured to form a hydrodynamically focused flow stream including an outer sheath fluid and an inner core fluid. A coherent light source is configured to illuminate ...
Methods and systems for optically characterizing a turbid material using a structured incident beam
(2010-04-08)
Methods and systems for optically characterizing a turbid sample are provided. A structured light beam is impinged on the sample. The sample includes an embedded region. A reflected light image of the structured light beam ...
Multi-wavelength beam splitting systems for simultaneous imaging of a distant object in two or more spectral channels using a single camera
(2016-09-29)
An optical imaging system and related methods are provided that acquire images of an object at a distance in different spectral regions using only one camera. The systems and methods are adaptable to applications where ...
Construction of realistic hybrid computational fetal phantoms from radiological images in three gestational ages for radiation dosimetry applications
(2019-10-10)
Radiation exposure and associated radiation risks are major concerns for fetal development for
pregnant patients who undergo radiation therapy or diagnostic imaging procedures. In order to
accurately estimate the radiation ...
