Leerdoelen Periode 2:
De student begrijpt het ontstaan van röntgenstraling en de daarop invloed hebbende parameters, de build-up, strooistraling, HVD en transmissie en kan deze toepassen in rekenvraagstukken.
De student kan de veel gebruikte grootheden, eenheden en si-prefixes hanteren en is beg...
,Karakteristek ssectrum (mono-energetsche straling) van wolfraam:
Röntgenbuis:
, Parameter voor radiologie:
- Buisssanning:
o kV (kiloVolt)
o Elektrische ssanning tussen anode en kathode
o Hogere ssanning geef rontgenstraling met hogere energie
- Buislading:
o mAs (milliAmsereSeconde)
o Elektrische lading is het aantal elektronen dat van kathode naar anode ‘stroomt’
o Meer lading geef meer rontgenstraling
Röntgenssectrum:
Röntgenssectrum en mAs:
Hoe hoger de buisssanning, hoe meer fotonen vrijkomen. De lijn in de grafek gaat dan omhoog.
