Review of Progress in Quantitative Nondestructive Evaluation
INTRODUCfiON This paper presents an approach to the reconstruction and parameter estimation of flaw models in NDE radiography. The reconstruction of flaw models rather than the flaw distribution itself reduces the required number of projections as well as the complexity of the measurement system [1, 2] . In this approach, crack-like flaws are modeled as piecewise linear curves, and volumetric flaws are modeled as ellipsoids. Our emphasis here is on a method for estimating the model parametersdoi:10.1007/978-1-4684-5772-8_93 fatcat:zspq4ojynjcj3lt6qkv4zya3oq
