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: X-ray Computed Tomography (CT) imaging is used to analyze the microstructural characteristics and evolution of asphalt mixtures, providing insights into their macroscopic performance. CT allows for the visualization and analysis of void spaces, permeability, deformation, cracks, and the distribution of components in asphalt mixtures. It is a powerful tool for monitoring and investigating damage processes and treatment effects.

Summary: In the study, the DLR algorithm showed superior image quality compared to Hybrid-IR and MBIR for cerebral non-contrast CT scans, with lower noise and improved tissue differentiation. Although DLR had a slightly longer reconstruction time, it provided significant advantages in image quality over the other two reconstruction methods.

Summary: The microstructure of an apatite-wollastonite glass-ceramic was analyzed using 2D microscopy, phase analysis, X-ray absorption, and synchrotron X-ray refraction computed tomography (XCT and SXRCT). The combination of these techniques allowed for comprehensive characterization of the microstructure at different scales. The material exhibited a complex microstructure with a glassy matrix and embedded fluorapatite and wollastonite crystals, forming spiked structures resembling sea urchins. SXRCT revealed the 3D distribution of these structures with excellent contrast, and SEM-EDX analysis identified them as composed of sub-micrometric fluorapatite and diopside crystals.

Summary: This study compared the image characteristics of a first-generation dual-source photon-counting computed tomography (PCCT) and a dual-source dual-energy CT (DECT) scanner at ultra-low radiation dose levels. The results showed that PCCT had high precision in Hounsfield unit (HU) measurements at various radiation dose levels, outperforming DECT at low doses and significantly reducing electronic background noise.

Summary: ILC has a greater tendency to metastasize to the peritoneum, retroperitoneum, and gastrointestinal tract compared to NST, with a infiltrative and hypometabolic nature that makes detection difficult. Late detection can lead to clinical complications such as liver failure, hydronephrosis, or bowel obstruction. Recognition of specific imaging features can aid in early detection and proper diagnosis of infiltrative metastatic ILC.

Summary: Medical imaging plays a crucial role in clinical diagnosis and disease research. This article introduces a new self-immolative polymeric chelate system that has a long circulation time in the blood and completely degrades into small molecules for excretion. The successful application of this system in micro-CT demonstrates its promising potential in the development of imaging contrast agents.

Summary: Although small-scale crystallizers have gained increasing importance, their hydrodynamic properties have not been thoroughly studied. This work characterizes an intensively stirred small-scale crystallizer and analyzes its fluid mechanics behavior. Single and multiphase computational fluid dynamics simulations show significant differences in the mixing characteristics of two types of stirrers, leading to variations in solids distribution. X-ray computed tomography measurements confirm spatial variations in solid distribution and highlight the potential errors in assuming a homogeneous suspension when modeling crystallization processes.

Summary: LEGO stop-motion animations were developed to engage first-year university students in mathematics topics through both concrete and abstract concepts in two and three dimensions. The animations, based on reducing cognitive load in multimedia learning principles, were found to enhance learning compared to static images, especially for dynamic systems and processes. The use of multimodal approaches including video and narration in the animations benefitted students in demonstrating mathematical problem solving.

Summary: In this study, a cryogenic electrical-substitution radiometer was utilized for the primary calibration of monochromatic photon beams at a synchrotron facility, in order to determine the intrinsic efficiency and dead layer thickness of an HPGe detector. This calibration method allowed for the calculation of efficiency up to 55 keV, where the active thickness of the detector is not a determining factor. Geometrical efficiency was also determined through measurements of a radioactive source at various distances.

The results showed that increasing the source-to-skin distance, patch thickness, and patch diameter will reduce the depth dose distribution, with the source-to-skin distance having the most significant impact on dose gradient.

Summary: The leakage neutron spectra of Lead samples were measured using a TOF technique, and MCNP simulations with different nuclear data libraries showed that JENDL-5.0 and JEFF-3.3 libraries have better agreement with experimental data. Differences in spectra mainly stem from variations in neutron reaction channels across the libraries, with ENDF/B-VIII.0 and CENDL-3.2 libraries being overestimated in certain energy ranges.

The results show that the addition of TeO2 can enhance the glass's ability to absorb photons and fast neutrons, and effectively suppress photon buildup. These glasses also exhibit exceptional gamma radiation and fast neutron moderating abilities, making them suitable for designing lead-free, transparent, and efficient radiation protection structures.

Summary: In gamma-ray spectrometric measurements, the decision threshold is determined by the observed value of the measurand. However, this dependence restricts its application to measurements with non-expressive indications. To address this issue, a recalculation of the decision thresholds based on the peak widths corresponding to expressive indications is proposed.
