High-Rate Volumetric Particle Tracking Microscopy (HR-VPTM) validation data

Published by National Institute of Standards and Technology | National Institute of Standards and Technology | Metadata Last Checked: August 02, 2025 | Last Modified: 2023-01-23 00:00:00
To verify and validate the HR-VPTM technique, both synthetic images and gels with embedded particles undergoingcontrolled deformations were used to compared known and reconstructed deformations at assorted strain-ratesor frame-rates. We simulated the light-field representation of particles undergoing motion with ray tracing andinvestigated the sensitivity of the measurement technique to synthetic noise floor and various motion fields. Inexperiments, a custom-built device deformed a hydrogel specimen in nominally simple shear at applied strain ratesapproximately 2 1/s, while light-field images were collected at approximately 500 frames per second frames per second. Files and formats include .tif images (raw data, input), .mat (reconstructed images, tracking results),.txt, .csv, and .yaml (all metadata).See also the data on MINDS@UW (https://minds.wisconsin.edu/handle/1793/83031), the accompanying paper in Experimental Mechanics (https://doi.org/10.1007/s11340-022-00885-z), and the complete code package released by collaborators at UW-Madison (https://github.com/francklab/HR-VPTM).
