For its radiological devices that work with X-rays or radioactive tracers, Siemens has developed a range of technologies – Combined Applications to Reduce Exposure (CARE) – that enable the dose to be reduced without compromising the image quality. These technologies include IRIS (Iterative Reconstruction in Image Space), a  method for the reconstruction of CT images, High Definition PET (HD-PET), a high-resolution positron emission tomography technology for molecular imaging, and a comprehensive package of dose-reduction features for interventional imaging, which are now available free of charge for customers.

GE Healthcare's approach is adaptive statistical iterative reconstruction (ASiR). ASiR is a low dose reconstruction technology that the company claims can reduce dose by up to 40–50% while maintaining image quality. The technology can be used on both helical and axial scans asnd is available as an upgrade to many CT scanners.

Other technology advances at the show are a bit more fun. For example, Matthew R. Amans, MD, of Weill Cornell Medical College presented his study on using a Wii video game remote (Wiimote, Nintendo) to access and view radiology images could be a viable alternative to the mouse and keyboard and may help alleviate the repetitive stress injuries radiologists so often report.

Object Research Systems (ORS; Montreal, Canada) also showcased its advanced visualization software ORS Visual, which provides a glasses-free 3-D experience.
