Riverain Medical, a provider of computer-aided detection (CAD) and diagnostic technologies, has received a Veterans Affairs (VA) contract for its OnGuard chest x-ray CAD technology. 

Used in conjunction with the reading of standard digital chest x-rays, the Dayton, Ohio-based Riverain said its OnGuard identifies solitary pulmonary nodules that may be early-stage lung cancer.

The contract streamlines the process for the VA and other authorized federal agencies to purchase the CAD software, according to the company.
