Spectrum + Filtratie
Figuur 1 CONTINUE SPECTRUM
 Continu spectrum
 Eigen filterwaarde buis
 Karakteristieke straling
 Invloed kV en mAs op spectrum
 Invloed extra filtratie

Inherent of eigen filter
1. anodemateriaal
2. wandmateriaal van de inzetbuis
3. olie tussen inzetbuis en buisomhulling
4. buisvenster, (dikke laag perspex)
Figuur 2 UITTREDEND SPECTRUM
5. spiegeltje in het diafragma
6. dun laagje perspex dat het
diafragmablok afsluit

fotonen kunnen niet afgeremd worden.
Bij een hoger kV neemt het stralencontrast af.
kV zorgt voor breder en hoger spectrum.
mAs zorgt alleen voor hoger spectrum.
Filter filtert onder de 30kV. Piek wordt lager.
Flatpanel detectoren
 Direct / indirect
 Verspreiding
 GadOx of CSI
 Spatiele resolutie

Postprocessing + Histogram
 Histogramanalyse
 LUT
 Windowing
 Unsharp mask

Karakterstieke straling is 0-10 keV. Deze filter je dan ook helemaal weg.
