[holding answer 12 November 2007]: As at July 2007 there were 22 machines installed in the national health service over 10 years old. Of these, 14 were awaiting delivery of replacement machines awarded under central programmes to purchase new and replacement equipment and facilities to provide better access to services. The remaining eight have been replaced via the central programmes but the trusts decided to retain their older machines in addition to meet local needs.
We do not hold information on whether these older machines are in routine clinical use. Some of these machines may be used for clinical research, training purposes or used as back up when another machine requires maintenance.
