Techniek semester 1

SPECT/CT reconstructietechnieken

o Inleiding
CT (computed tomography) SPECT (single photon emission computed
tomography
- Stralingsbron buiten het lichaam - Stralingsbron in het lichaam
- Rij detectoren meet straling - Rij detectoren meet straling




Bij CT en SPECT dient de detecteerde straling omgezet te worden in een beeld. Dit proces
noemen we reconstructie. De reconstructie is voor CT en SPECT dezelfde techniek.

Als de röntgenbuis van links naar rechts beweegt dan levert dat een intensiteitsprofiel op.
Het intensiteitsprofiel wordt omgerekend naar een verzwakkingsprofiel. Het
verzwakkingsprofiel wordt gebruikt voor de ruwe data.

, De detector meet het absorptieprofiel voor enkele hoeken.




Zwart = geen absorptie
Wit = wel absorptie

Verschillende reconstructietechnieken:
- Filtered back projection (FBP)
- Iteratieve reconstructie
- Spiraal CT

o Filtered back projection (FBP)
De simpelste reconstructie is directe terug projectie. Hierbij wordt het omgekeerde van
projectie gedaan.
