INDUSTREX
HPX-ARC
1025 PH and 1043 PH
DR Detectors
Bending the limits of DR.
The HPX-ARC is 98 µm detector that
delivers high-resolution images for better
defect recognition and code compliance.
With a smooth and bendable design, it
comes in two sizes that conform to various
objects with the flexibility to go from a
flat position down to a 2-inch diameter
(1025 PH) or 4-inch diameter (1043 PH).
With bendable DR technology,
customers will realize easier
set-up, faster time to image,
less dose required to capture
images, and instant image
processing versus film or CR.
INDUSTREX Digital Viewing Software for CR and DR
Operates seamlessly across our ever expanding CR and DR modalities. Easily add any of our
digital imaging systems without having to purchase and learn new software. Easy to set-up
with a user-friendly interface design to acquire both CR and DR images for detailed analysis.

Innovative BHEC techniques enable more accurate crack sizing
in multilayer fastener sites, enhancing maintenance decisions
through improved model calibration, inversion, and material-
specific surrogate models.
57 MULTIVARIATE PROBABILITY OF DETECTION

VARIABLES AND HIGHER-ORDER RESPONSE
MODELS
CHRISTINE E. KNOTT, CHRISTINE SCHUBERT KABBAN, AND
JOHN C. ALDRIN
A new methodology extends probability of detection (POD)
modeling to include multiple variables and interactions,
enabling more accurate â vs. a analysis using advanced statistical
transformations and simulations.
73 PROBABILISTIC SIZING OF A FATIGUE CRACK
ON TYPE 304 AUSTENITIC STAINLESS STEEL
FROM EDDY CURRENT SIGNALS
TAKUMA TOMIZAWA AND NORITAKA YUSA
Using eddy current signals and a Bayesian inverse algorithm, this
study probabilistically estimates fatigue crack size in stainless steel,
accounting for electromagnetic property changes from damage.
