Large Field of View Quantitative Phase Imaging of Induced Pluripotent Stem Cells and Optical Pathlength Reference Materials

February 23, 2018
Author(s)
Edward J. Kwee, Alexander W. Peterson, Jeffrey R. Stinson, Michael W. Halter, Liya Yu, Michael P. Majurski, Joe Chalfoun, Peter Bajcsy, John T. Elliott
Induced pluripotent stem cells (iPSCs) are reprogrammed cells that can have heterogeneous biological potential. Quality assurance metrics of reprogrammed iPSCs will be critical to ensure reliable use in cell therapies and personalized diagnostic tests. We

From Image Tiles to Web-Based Interactive Measurements in One Stop

January 4, 2017
Author(s)
Antoine Vandecreme, Michael P. Majurski, Joe Chalfoun, Keana Scott, John Henry Scott, Mary C. Brady, Peter Bajcsy
This article aims at introducing readers to a web-based solution useful for interactive measurements of centimeter-sized specimens at nanoscales. Modern imaging technology has enabled nanoscale imaging to become a routine process. As the imaging technology

Enabling Interactive Measurements from Large Coverage Microscopy

Peter Bajcsy, Antoine Vandecreme, Julien M. Amelot, Mary C. Brady, Joe Chalfoun, Michael P. Majurski
Microscopy could be an important tool for characterizing stem cell products if quantitative measurements could be collected over multiple spatial and temporal scales. With the cells changing states over time and being several orders of magnitude smaller

Methodology for Increasing Image Feature Measurement Accuracy

June 30, 2016
Author(s)
Michael Paul Majurski, Joe Chalfoun, Steven Lund, Peter Bajcsy, Mary C. Brady
Motivation Image features are computed in cell biology to derive quantitative information regarding cell state, differentiation, biological activity, and cell dynamics. The accuracy of any biological conclusions depends on the accuracy of the measured

Survey Statistics of Automated Segmentations Applied to Optical Imaging of Mammalian Cells

January 8, 2016
Author(s)
Peter Bajcsy, Antonio Cardone, Joe Chalfoun, Michael W. Halter, Derek Juba, Marcin Kociolek, Michael P. Majurski, Adele P. Peskin, Carl G. Simon Jr., Mylene H. Simon, Antoine Vandecreme, Anne L. Plant, Mary C. Brady
The goal of this survey paper is to overview cellular measurements using optical microscopy imaging followed by automated image segmentation. The cellular measurements of primary interest are taken from mammalian cells and their components. They are

Shape Descriptors Comparison for Cell Tracking

October 15, 2015
Author(s)
Michael P. Majurski, Christopher Zheng, Joe Chalfoun, Alden A. Dima, Mary C. Brady
New microscope technologies are enabling the acquisition of large volumes of live cell image data. Accurate temporal object tracking is required to facilitate the analysis of this data. One principle component of cell tracking is correspondence, matching
