The Consistent Presentation of Images (CPI) Integration Profile is a part of the IHE Radiology Technical Framework.

This profile specifies a number of transactions that maintain the consistency of presentation for grayscale images and their presentation state information (including user annotations, shutters, flip/rotate, display area, and zoom). This profile also defines a standard contrast curve, the Grayscale Standard Display Function, against which different types of display and hardcopy output devices can be calibrated. Takes care of hardcopy and softcopy grayscale and Presentation State, i.e., matches the appearance of images on films from different printers with images displayed on different monitors. This profile is critical, not only to match the grayscale but also to allow annotations and image manipulations to be archived and retrieved between different vendors.
