7.2
X-ray Shielding in the Scanning Room
The gantry (scanner) and the patient couch in the patient environment must be installed in a
scanning room provided with X-ray shielding. The console is installed in the control room outside
the scanning room. Operations related to X-ray generation are basically performed from the
control room. Appropriate X-ray shielding must be provided in the scanning room according to the
legal requirements of each country and region.
If people cannot enter the area below the floor where the X-ray CT system is to be installed (for
example, if the system is installed on the ground floor of a building with no basement), X-ray
shielding work for the floor is not necessary.
Note that it is recommended that appropriate X-ray shielding be provided according to the ICRP
advisory in countries and regions where there are no legal requirements concerning X-ray
protection.
7.3 Support
The rooms in which the units are to be installed must be able to withstand the load of the units.
For the mass of each unit, see item (8) "External dimensions and mass" of section 4.
7.4
Floor Structure of the Scanning Room
The structure of the floor must permit the driving of anchor bolts for securing the gantry and the
patient couch. It is recommended that the thickness of the floor should be more than 150 mm. To
ensure levelness of the installation floor for the base, perform floor levelling work using epoxy resin
for the gantry and patient couch.
7.4.1
Floor-leveling work using epoxy resin
Complete this work before carrying in the system because a period of 2 to 5 days is required for
the epoxy resin to harden (the actual time required depends on the temperature).
