System Manual

Setting the maximum skin dose rate

Prerequisites

•

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

•

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

•

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).
