• LSS: Low Speed Start option
• HSS: High Speed Start option
All Values are valid for 3-phase generator power line and large focal spot.
Values for other exposure conditions can be determined using the technical
data of the generator and the data sheets of the X-ray tubes.
In regular use these maximum exposure settings will not create doses that can
cause deterministic effects. Effective patient doses for typical exposures are
listed in Test Report for IEC 60601-1-3.
Switching between small focus and large focus may have a delay of a few
seconds. The focus is controlled by a relais and it requires the filament to cool
down before switching.
The settings of kV and mAs or of mA and ms are defined by an algorithm. The
highest mA setting is used for which the kV can be reached by the system and
the exposure time is not lower than 4 ms. When the kV setting is changed, the
value of mA and ms are adjusted automatically to keep the mAs value
constant, within the boundaries of generator or X-ray tube limitations.
