Opposition critic Kerry Towle says the cost to taxpayers is almost $10 million.
The Wildrose says the information was recently leaked to them by an inside source.
The Wildrose says Alberta Health Services bought the machines at the end of the 2011-2012 budget year for use in Edmonton.

Premier Alison Redford said the Wildrose comments are only allegations and have not been proven.
