University College London (UCL), ISDI and Spectrum Logic have published a study on their Dual-energy (DE) X-ray Detector.

The Spectrum Logic/ISDI team worked with UCL on a study which has just been published in Journal of Applied Physics ‘Design and fabrication of a sandwich detector for material discrimination and contrast cancellation in dual-energy based X-ray imaging’ . The team developed a ‘Sandwich Detector’ which consists of two detectors one placed on top of the other and can be used for dual-energy imaging.

Celebrating Rosalind Franklin's Contribution to the Discovery of DNA's Structure

Rosalind Franklin was a pioneering British biophysicist and X-ray crystallographer born on July 25, 1920, in London. She played a crucial role in understanding the molecular structures of DNA, RNA, viruses, coal, and graphite. Excelling in science from a young age, she earned her Ph.D. from the University of Cambridge. Franklin is best known for her pivotal contributions to the discovery of DNA's double helix structure during her tenure at King's College London in the early 1950s. Her meticulous X-ray diffraction work led to the capture of Photograph 51, an image that provided critical evidence of DNA's helical structure.

Water-Cooled 2824HR and 2824HS CMOS X-ray Detectors for Low Noise Dynamic Imaging

Spectrum Logic has now released water-cooled versions of the 2824HR and 2824HS detectors to further improve their market leading performance. In the cooled detectors water circulates between a chiller unit and a heat exchanger in the detector housing. This cools the detector and maintains a stable temperature which is configured at the chiller. The stable temperature reduces dark noise and stability of the temperature of the sensor array means that the offset correction is stable and does not suffer from variations in the dark image due to temperature changes in the CMOS sensors in the detector.
