Summary: A dual imaging modality of pinhole XRF and CT imaging system and L-shell XRF detection system were successfully developed. The developed systems are a promising modality for in vivo imaging and ex vivo quantification for preclinical studies using MNPs. In addition, we discussed further improvements for the routine preclinical applications of the systems.

Summary: To study the three-dimensional microstructure and calcium dynamics of human heart organoids (hHOs), a dual-modality imaging system combining optical coherence tomography (OCT) and fluorescence microscopy was developed. OCT provided high-resolution structural information while fluorescence imaging indicated the electrophysiology of the hHOs' beating behavior. This imaging platform proved to be a powerful tool for studying and assessing hHOs in vitro, with potential applications in disease modeling and drug screening.

Summary: This technical note introduces a new DECT protocol and iodine map reconstruction technique for visualizing membranes in chronic subdural hematoma. Results showed that all 50 hematomas had an enhancing external membrane, with 13 having an incomplete internal membrane and 23 having a complete internal membrane. A spandrel sign indicating partial or complete formation of the internal membrane was observed in 36 hematomas.

Summary: The segmentation of tomographic images of battery electrode is crucial for material characterization and electrochemical simulation. We propose a deep learning approach using a CNN for real-world battery material datasets, achieving high accuracy with limited labeled data. We also address the uncertainty in the segmentation quality by identifying human bias in the training data.

Summary: This study assessed the impact of scan modes and reconstruction kernels using a novel dual-source photon-counting detector CT (PCD-CT) on the lumen visibility and sharpness of different stent sizes. The results showed that the UHR acquisition mode and sharp reconstruction kernels significantly improved the in-stent lumen visibility and sharpness, especially for smaller stent sizes.

Summary: In recent decades, advanced experimental techniques such as X-ray and neutron imaging have provided unprecedented insights into the behavior of geomaterials. Neutron imaging, with its unique properties including high sensitivity to hydrogen, high penetration into metals, and isotope sensitivity, has shown to be an extremely valuable tool in experimental geomechanics. Recent developments, such as combining neutron imaging with simultaneous X-rays and improving spatial and temporal resolution, are highlighted for their potential contributions to the field.

Summary: In the study, a generative adversarial network (GAN) was designed to fuse the data from electrical capacitance tomography (ECT) and electromagnetic tomography (EMT) for accurate phase volume measurement in gas-liquid-solid (G-L-S) three-phase flow. A simulation approach was proposed to provide realistic measurement samples, demonstrating the high precision of electromagnetic property reconstruction and generalization ability of the fusion model across various flow regimes. Errors in calculated phase fractions were less than 0.15 in both simulations and experiments, showing the effectiveness of the approach.

Summary: The study aimed to develop a dual-energy CT method for differentiating and quantifying high-Z contrast elements, evaluating the limitations based on element concentration and atomic number. Results showed that dual-energy CT can effectively differentiate and quantify high-Z elements with high accuracy. Differentiation between elements was proportional to the isoattenuating HU values.

Summary: The contributions of the interfacial transition zone (ITZ) to mass transport in cement-based materials are still unclear. This study uses neutron and X-ray tomography to investigate the complexities of unsaturated moisture flow. The experiment shows that there is no evidence of water preferentially migrating in the ITZ region during unsaturated flow compared to the bulk cement paste.
