5.4 BEAM FILTER SELECTION
Diamond has three X-ray beam filters: Molybdenum Mo (0.025mm),
Rhodium Rh (0.025mm) and Aluminum Al (0.50mm). If required, Diamond
can be set to automatically select the most appropriate X-ray beam filter.
All filters are motorized and the beam filters can be used automatically, if
Auto Filter is switched on. Molybdenum and Rhodium are used in the kV
range of 15 to 35 kV, whilst the Al-filter is used in the kV range of 36 to 39
kV.
Manual selection of the beam filter is the default setting, but the filter can
also be selected automatically in Auto-kV and Auto-Time modes. The
selected filter is indicated with a light next to the appropriate filter
selection button. For large and dense breasts, the Rhodium filter should
be used to reduce the exposure time and the patient dose.
NOTE!
After the exposure, the timer display shows the actual exposure time.
NOTE!
When using the Rhodium filter, do not increase the kV-setting.
