IEC 60601-2-44:2009+A1:2012 applies to the basic safety and essential performance of CT scanners. The scope of IEC 60601-2-44:2009 is limited to CT scanners intended to be used for both head and body characterised by an enclosure of the X-ray source(s) and imaging detector(s) in a common protective cover in the shape of a toroid. It includes safety requirements for the X-ray generators used in CT scanners, including those where high-voltage generators are integrated with an X-ray tube assembly. This third edition cancels and replaces the second edition published in 2001 and its Amendment 1 (2002). This edition constitutes a technical revision primarily related to radiation protection and control. The contents of the corrigendum of May 2010 have been included in this copy. This consolidated version consists of the third edition (2009) and its amendment 1 (2012). Therefore, there is no need to order the amendment in addition to this publication.
