  2. Inhoud Aanleiding Profielen PDD’s Bestandsformaten Afgeleide resultaten

  3. Asymmetrisch veld ?

  4. Geen penumbra ?

  5. Standaardprofiel: welke eisen? NCS-8 ? Controle ten opzichte van commissioning ? Controle ten opzichte van planningssysteem ? Controle ten opzichte van generieke bundel ?

  6. Standaardprofiel Beam Modulator: bol ? NCS-8 ?

  7. Bijregelen: energie en/of symmetrie?

  8. Oplossing: vergelijking met referentie Hoe te vergelijken? Hoe leg je verschillen vast? Welke normen?

  9. Bijregelen ten opzichte van referentie

  11. Bijregelen ten opzichte van referentie?

  12. Bijregelen ten opzichte van referentie energie en/of symmetrie?

  17. Geen penumbra

  18. Vergelijking met generieke bundel nieuw toestel, ander model ?

  19. Vergelijking met generieke bundel maak alias

  20. Vergelijking met generieke bundel normalisatiepunt ok?

  21. Vergelijking met generieke bundel normalisatie op gemiddelde flattened area

  22. FFF: veldgrenzen data: NKI/Thijs Perik, referentie is tot inplane verbouwd crossplane-profiel

  23. FFF: verschillen is (dosis)verschil nog juiste parameter?

  25. settings

  26. pdd

  27. pdd: configuratie

  28. pdd: NCS-18 + generieke bundels relatieve normalisatiepunt absolute normalisatiepunt

  36. Bistromathics http://bistromath.kegge13.nl "Bistromathics itself is simply a revolutionary new way of understanding the behavior of numbers. Just as Albert Einstein's general relativity theory observed that space was not an absolute but depended on the observer's movement in time, and that time was not an absolute, but depended on the observer's movement in space, so it is now realized that numbers are not absolute, but depend on the observer's movement in restaurants." Douglas Adams; Life, the Universe and Everything, 1982
