Abstract: Embodiments are directed to methods and systems that generate images with structural features, including microstructures, from exemplar images. Such embodiments use an image generator steered by input attributes to generate structural features of synthetic images with the specified input attributes. The generated attributes can either accurately match the exemplar attributes or vary according to user control, without being limited to attribute combinations that are represented in the exemplar data. This enables extrapolation to novel structures that can be generated, analyzed, and optimized in silico without incurring additional data acquisition costs, e.g., costs for manufacturing, sample preparation, imaging, and/or segmentation. Embodiments enable accurate synthesis of images with target attributes of structure features, including on larger spatial domains, higher dimensions, and attributes not directly controlled or supervised during model training.

Abstract: Embodiments determine the density of materials and objects imaged using computed tomography (CT). An embodiment co-images a material of unknown density with a calibrant of known density. The digitally reconstructed CT images are segmented into the unknown material phase and the known material phases of the calibrant. Image intensity histograms of the unknown material are obtained. Using the known calibrant densities, an intensity-density mapping is calculated to determine the unknown material density based on its measured CT intensity. The method described herein utilizes a novel deconvolution of the intensity histograms to correct for CT imaging artifacts that impact the material phase intensities. The density of micronized materials and features such as particles, microspheres, porosity, and multiphase composites which are difficult to measure with conventional techniques can be measured using the embodiments.
