Prediction of Cellular Identities from Trajectory and Cell Fate Information
Baiyang Dai, Jiamin Yang, Hari Shroff +1
Determining cell identities in imaging sequences is an important yet challenging task. The conventional method for cell identification is via cell tracking, which is complex and ca…
Simulation of Muon Tomography Projections to Image the Pyramids of Giza
Mira Liu
Purpose: A geometric simulation of a possible two-plane detector was developed to test the abilities of the detector to generate high-resolution images of the Great Pyramid using m…
Phase Diverse Phase Retrieval for Microscopy: Comparison of Gaussian and Poisson Approaches
Nikolaj Reiser, Min Guo, Hari Shroff +1
Phase diversity is a widefield aberration correction method that uses multiple images to estimate the phase aberration at the pupil plane of an imaging system by solving an optimiz…
Simulation of a Compton-based detector for low-dose high-resolution time-of-flight positron emission tomography
Kepler Domurat-Sousa, Cameron M. Poe, Maya S. McDaniel +7
Two major challenges in time-of-flight positron emission tomography (TOF-PET) are low spatial resolution and high radioactive dose to the patient, both of which result from limitat…
Spatio-angular fluorescence microscopy III. Constrained angular diffusion, polarized excitation, and high-NA imaging
Talon Chandler, Hari Shroff, Rudolf Oldenbourg +1
We investigate rotational diffusion of fluorescent molecules in angular potential wells, the excitation and subsequent emissions from these diffusing molecules, and the imaging of…
Spatio-angular fluorescence microscopy I. Basic theory
Talon Chandler, Hari Shroff, Rudolf Oldenbourg +1
We introduce the basic elements of a spatio-angular theory of fluorescence microscopy, providing a unified framework for analyzing systems that image single fluorescent dipoles and…
Joint Reconstruction of Multi-channel, Spectral CT Data via Constrained Total Nuclear Variation Minimization
David Rigie, Patrick La Riviere
We explore the use of the recently proposed "total nuclear variation" (TNV) as a regularizer for reconstructing multi-channel, spectral CT images. This convex penalty is a natural…
X-ray tomography system to investigate granular materials during mechanical loading
Athanasios G Athanassiadis, Patrick J. La Rivière, Emil Sidky +3
We integrate a small and portable medical x-ray device with mechanical testing equipment to enable in-situ, non-invasive measurements of a granular material's response to mechanica…
