Clinical Examples: Scanning with the Right Dose

CARE Right aims at finding the right dose for every individual patient. What matters is the right balance between image quality and radiation dose. All of CARE Right’s individual areas – right dose technology, right dose levels, and right dose management – come together in the following examples.

CARE Right. Committed to the right dose in CT.
