Abstract

The use of mobile head computed tomography (CT) equipment in intensive care is ofbenefit to unstable patients with brain injury. However, ionising radiation in a wardenvironment presents difficulties due to the necessity to restrict the exposure tostaff and members of the public according to regulation 8(1–2) of the IonisingRadiation Regulations 1999. The methodology for enabling the use of a mobilehead CT unit in an open ward area is discussed and a practical solution given.This required the reduction in scatter doses through the installation of extrainternal and external shielding, and a further reduction in annual scatter dose byrestricting the use of the equipment based on a simulation of the annual wardworkload.
