An international team of researchers has developed a groundbreaking X-ray mammography technique that produces high-resolution 3D images of the breast using a radiation dose approximately 25 times lower than conventional 2D digital mammography. This innovative method also enhances the spatial resolution of 3D high-energy X-ray CT images by up to three times. The findings were published on the same day in the online edition of the *Proceedings of the National Academy of Sciences*.
Currently, the standard method for breast cancer screening is "Double View Digital Mammography," which captures only two images of the breast tissue. This limitation leads to missed diagnoses in 10% to 20% of cases. Additionally, the technique can sometimes produce false readings, increasing the risk of misdiagnosis.
While CT scans offer detailed 3D views of internal organs, they are not commonly used for breast cancer diagnosis due to concerns about radiation exposure. The breasts are particularly sensitive to radiation, and repeated CT scans could pose long-term health risks.
The new technology aims to address these challenges. Researchers are currently testing it using synchrotron X-rays, and if successfully implemented in hospitals, it could complement traditional mammography as a more accurate diagnostic tool.
By combining high-energy X-rays with phase-contrast imaging and advanced EST mathematical algorithms, the system reconstructs CT images from X-ray data. This approach significantly reduces the required radiation dose—by about six times—because high-energy X-rays make soft tissues more transparent. Phase-contrast imaging further decreases the number of X-rays needed, while the EST algorithm achieves the same image quality with four times less radiation. Using this method, the research team captured 512 images from various angles, resulting in a 3D image with higher clarity, contrast, and overall quality compared to traditional mammograms.
This achievement is the result of a decade-long effort by the European Synchrotron Radiation Source (ESRF) Research Center, along with the University of Munich and the University of California, Los Angeles. The researchers hope to extend this technology to visualize other diseases early and develop a practical X-ray source to bring the technology into clinical use sooner.
LED Light Tower
LED Light Tower
A LED light tower is a portable lighting system that uses LED (Light Emitting Diode) technology to provide bright and efficient illumination. It is commonly used in construction sites, outdoor events, emergency situations, and other applications where temporary lighting is needed.
LED light towers are designed to be easily transported and set up, with features such as telescopic masts and wheels for mobility. They typically consist of multiple LED light fixtures mounted on a tall mast, which can be extended to different heights to provide optimal lighting coverage.
LED technology offers several advantages over traditional lighting sources such as halogen or metal halide lamps. LEDs are more energy-efficient, providing the same or higher light output while consuming less power. They also have a longer lifespan, reducing the need for frequent bulb replacements. LED light towers are also more durable and resistant to shock and vibration, making them suitable for rugged environments.
Some LED light towers come with additional features such as adjustable light angles, remote control operation, and built-in power outlets for other equipment. They can be powered by electricity from a generator or connected to a power source, and some models also offer solar-powered options for eco-friendly operation.
Overall, LED light towers offer a reliable and efficient lighting solution for various applications, providing bright illumination while minimizing energy consumption and maintenance requirements.
