Chinese researchers develop 6 kg CT scanner they say is world's smallest
A company founded by Chinese Academy of Sciences researchers has developed a 6 kg CT scanner that it says is the world's smallest, a portable device built to image the inside of small objects.
A Chinese research team has created the world's smallest and lightest CT scanner, weighing just 6 kg. The device, called the Xtomo-Cube, was developed by Rayim, a firm in Jinan, Shandong Province, and the Institute of High Energy Physics. Measuring 14 by 13.2 by 22 centimeters, the scanner is small enough to fit in one hand.
Liu Baodong, Rayim's general manager, said the scanner can produce detailed 3D images of samples like chicken bones and snail shells at a resolution of 80 micrometers, or about the width of a human hair. The device's scanning field is 16 millimeters across.
Weighing significantly less than the previous smallest CT system, which was developed in Germany and weighed 19 kg, the Xtomo-Cube is designed for on-site work at archaeological digs and geological surveys. It draws only about 200 watts of power and can operate outdoors on a standard portable power supply.
All components of the scanner, including the X-ray source, rotating stage, detector, and software, were developed domestically. The scanner's raw imaging data is available to researchers, enabling them to develop image reconstruction algorithms and train AI models.
