On Aug. 7, 2009, Confirma was acquired by Milwaukee, WI-based Merge Healthcare in an all-stock transaction valued at $22 million. Confirma was renamed Merge CAD and operated as a business unit of Merge Healthcare.

Confirma investors will own about 8.5 percent in Merge Healthcare upon closing of the deal, expected to occur in September.

Bellevue-based Confirma marketed the CADstream software package and had installed more than 1,200 systems for breast and prostate MRI.
