Advance in Silicon Photomultiplier Technology to Benefit Medical Imaging Systems

Monday, November 1st, 2010

Medical imaging is one application that could benefit from an advance in silicon photomultiplier technology developed by Royal Philips Electronics. The company recently announced that it had scaled a single-pixel sensor into a fully integrated 64-pixel sensor with a sensing surface greater than 10 square centimetres. In addition to medical ...

Researchers Use Novel Imaging Compound to Track Cancer Cells

Wednesday, December 17th, 2008

Researchers have developed a compound that illuminates live cancer cells, enabling the spread of breast cancer cells in mice to be tracked using an endoscope. While fluorescent compounds for cancer detection have been developed before, such substances continue to fluoresce after diffusing to new locations, making it difficult to differentiate ...
