Setting the maximum skin dose rate 5
Prerequisites 5
• You must program one of the FL curves S2, HC2 or IODINE.
• The FL curves S2, HC2 or IODINE should be used for the following adjustment.
• The X-ray tube cover must be installed.
• Use the dose ionization chamber of the dose measurement device to measure dose
rates greater than 10R/min.
• If you are using an area dose product measurement device, mount the dose measure-
ment chamber above the radiation exit port of the SIREPHOS.
Measurement 5
• Switch on fluoroscopy.
• Read and record the value displayed on the dose rate meter.
• If the value measured exceeds 9 R/min, the maximum tube current must be reduced. If
the value measured is less than 9 R/min, the tube current does not need to be reduced.
• Switch fluoroscopy off.
Setting the maximum skin dose rate is necessary only for coun-
tries where DHHS regulations apply.
Fig. 2
If the maximum tube current was already reduced, the mA value
displayed at 110kV should be recorded and used for the calcula-
tion. The maximum skin dose rate to be set should equal 9R/min.
NOTE
Preparations 5
• Attach the dose ionization chamber
at a distance of 30 cm from the I.I.
housing (Fig. 2).
• Select one of the FL curves S2 / HC2
or IODINE according to the program-
ming. (Push-key)
• Briefly release fluoro.
• Select kV stop mode and enter
110 kV (5 mA).
