Abstract: According to various embodiments a device may provide an interactive searching interface for securely searching of textual content across a plurality of documents stored in a plurality of repositories comprising heterogenous data, the securely searching of the textual content comprising using a flexible search criteria and enforcing user access privileges to the plurality of documents A device may use unified searching, using a unified search criteria definition, the plurality of repositories in response to the feedback from the user, the unified searching being interactive, iterative, and using a unified index resulting in faster query response times than the metadata searching the plurality of repositories.

Abstract: A method of diagnostic imaging is disclosed herein. The method includes acquiring CT projection data at a first x-ray energy level and a second x-ray energy level. The method includes reconstructing a first image pair using a basis material decomposition algorithm and the CT projection data. The method includes displaying a first image from the first image pair. The method includes transforming the first image pair into a second image using image data from the first image pair. The method also includes displaying a second image. A CT system is also disclosed.
