A NEW ELECTRON SPECTROSCOPY SYSTEM FOR MEASURING ELECTRON EMISSION FROM FAST ION INTERACTIONS WITH ATOMIC, MOLECULAR, AND CONDENSED PHASE TARGETS
(East Carolina University, 2016-07-25)
A new electron spectroscopy system has been developed for measuring electron emission from gas and solid targets induced by fast ion impact. This system uses an ultrahigh-vacuum compatible cylindrical deflector analyzer, ...
Feasibility Study of Dual Energy Radiographic Imaging for Target Localization in Radiotherapy for Lung Tumors
(2014)
Purpose
Dual-energy (DE) radiographic imaging improves tissue discrimination by separating soft from hard tissues in the acquired images. This study was to establish a mathematic model of DE imaging based on intrinsic ...
A new assessment model for tumor heterogeneity analysis with [18]F-FDG PET images
(2016-01)
It has been shown that the intratumor heterogeneity can be characterized with quantitative analysis of the [18]F-FDG PET image data. The existing models employ multiple parameters for feature extraction which makes it ...
Four-Dimensional In Vivo Dosimetry By Dose Reconstruction Using Continuous Epid Images And Phase Sorting Method
(East Carolina University, 2015)
In vivo dosimetry is widely used for patient specific dose evaluation and treatment verification in external beam radiation therapy (EBRT). There is a growing interest in using an electronic portal imaging device (EPID) ...
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 ...
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 ...
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 ...
