Penza State University in Russia Develops Training Simulator for X-ray Image Defect Recognition

Researchers at Penza State University in Russia have developed an interactive training simulator for identifying defects in X-ray images, aimed at helping medical students and residents more accurately assess abnormalities in medical images and understand the physical causes behind different image defects. X-ray image quality directly affects the efficiency of pathological change detection and clinical diagnostic judgment. Factors such as equipment condition, exposure parameters, radiation dose, and quantum noise levels can all lead to degraded image quality. Therefore, radiologic technologists and radiologists need not only to identify lesions in images, but also to assess image quality and determine whether defects such as low contrast, noise, blur, and artifacts may affect diagnosis...

German BESSY II 3D Magnetic Field Experiments Reveal Mechanism of Weak Magnetic Field Control over Magnetic Textures

A team at the Helmholtz-Zentrum Berlin (HZB) in Germany has made progress in controlling magnetic textures in the magnetic material (Fe0.63Ni0.3Pd0.07)3P (abbreviated as FNPP) through 3D magnetic field experiments conducted at the BESSY II synchrotron facility. The research shows that a very small external in-plane magnetic field is sufficient to alter the magnetic stripe structure in this material, providing new experimental evidence for the development of functional magnetic materials for spintronics. FNPP is a magnetic material that exhibits complex magnetic structures at room temperature, making it a focus of spintronics research. Spintronics is considered promising for lower-energy data processing and novel data storage applications. However, to achieve practical applications, the key lies in...

South Korean research team reveals that water storage capacity of cold subducting slabs has been underestimated using synchrotron radiation sources

A research team led by Professor Yongjae Lee of the Department of Earth System Sciences at Yonsei University in South Korea has recently found that in cold, rapidly descending tectonic subduction zones, crustal rocks may transport up to 1 trillion kilograms of water to the mantle each year—approximately twice the previous estimate. The findings have been published in Nature Communications. Subduction zones are regions where Earth's tectonic plates converge and one plate descends beneath another, often accompanied by volcanic and seismic activity. For a long time, the academic community has generally believed that serpentinite, a water-bearing rock, gradually dehydrates as it descends with the plate due to increasing pressure and temperature, and the released water further promotes melting of the overlying plate and is associated with the formation of volcanic arc chains.

Domestically Developed "Palm-Sized CT" Debuts: 6 kg Micro X-ray CT Enables 3D Non-Destructive Testing

The XTOMO-CUBE series micro-CT, independently developed by Ruiying Detection Technology (Jinan) Co., Ltd., recently made its debut. With dimensions of 140×132×220 mm and a total weight of approximately 6 kg, the device can be held in one hand and is dubbed the "palm-sized CT." It can scan small-sized samples such as chicken bones, snail shells, and capsule tablets, revealing their internal three-dimensional structures. According to reports, CT stands for computed tomography technology. Compared with traditional CT equipment, the XTOMO-CUBE integrates key modules such as a miniaturized X-ray source, rotation stage, and detector into a compact body, paired with fully self-developed software capable of completing processes including projection data acquisition, CT image reconstruction, and 3D rendering. The...

Russian scientists use 3D-printed tungsten grid to improve X-ray imaging quality, potentially reducing patient radiation exposure

The press service of the Russian Ministry of Education and Science recently stated that a Russian research team has used 3D printing technology to manufacture a tungsten-based anti-scatter grid for X-ray machines, with partition thickness only one-third that of similar products. The researchers believe this achievement could help reduce patient radiation exposure during X-ray examinations while maintaining medical image quality. During X-ray imaging, some rays scatter after passing through human tissue, creating background noise that weakens image contrast. Clinical equipment typically suppresses such interference through anti-scatter grids. Traditional anti-scatter grids are mostly made of lead, but lead has low mechanical strength and imposes high requirements on processing techniques, resulting in...

Japan's PF Launches Quantum Multi-Beam Experiments, Achieving Simultaneous Hard and Soft X-ray Measurements

The Photon Factory, a synchrotron radiation facility at the Institute of Materials Structure Science, High Energy Accelerator Research Organization (KEK) in Japan, has recently launched collaborative experiments on the development and research multi-purpose beamlines BL-11A and BL-11B, achieving simultaneous irradiation of the same sample with hard and soft X-rays at the same position. The research results will be published in the international academic journal *Review of Scientific Instruments*. The Photon Factory uses electrons moving at near-light speed to generate high-brightness X-rays, known as synchrotron radiation, for studying material structures and properties. Among these, hard X-rays are better suited for observing the internal structure of materials, while soft X-rays are ideal for analyzing material surfaces and electronic states. Previously, at synchrotron radiation facilities, the two types of X-rays typically had to...

Portable X-ray Equipment in the U.S. Used for On-Site Assessment of American Football Injuries

As the 2026–2027 American football season approaches, team training camps, player evaluations, and medical support preparations are getting underway. Given the risk of acute sports injuries from the high-intensity physical contact in American football, portable X-ray equipment is being used to improve the efficiency of injury assessment on the sidelines and at training facilities. According to reports, American football players are prone to fractures, sprains, joint dislocations, and contusions. Relevant data indicates that the incidence of severe injuries such as fractures, dislocations, and contusions in this sport is higher than in other sports, with fractures accounting for approximately 10% of all football injuries. Such injuries typically require X-ray radiography to aid diagnosis, but traditional X-ray machines are bulky and fixed in place, usually requiring use in facilities with appropriate shielding. Injured players often need to be transported to the radiology department for examinations, which may delay diagnosis and treatment decisions.
