Mouse CT scanner. Researchers watch a laboratory mouse (Mus musculus) in a computed tomography (CT) scanner. This is MicroCAT, a new CT scanner that was developed to study small animals like mice by creating images with 10 times the resolution of conventional scanners. The mouse's development can be monitored; mice such as this are bred for genetic analysis. CT scans are slice images through the body made using X-rays. MicroCAT can also take standard X-ray images. Systems like this may one day be used for mammography, as they could detect breast cancer at a very early stage. The scanner was developed at the Department of Energy's Oak Ridge National Laboratory, USA.
