[Castor-users] PET reconstruction from a binary LUT file

[Daiki HAYAKAWA]

Dear CASToR users, 

We are trying to reconstruct PET image from a binary LUT file following the page 21 in the general document. The sensitivity map looks fine but reconstructed images make no sense. We think that there would be a problem regarding to castor ID for each detector (but we are not fully sure).
We currently create a binary LUT file as the for loops (*1) suggested in the document. Does the castor ID for detectors follow the order like (*2)?

Any suggestions/comments are welcome.

Thank you and kind regrads,
Daiki Hayakawa


(*1)
for(iLayer=0;iLayer<NLayer;iLayer++)
    for(iRing=0;iRing<NRing;iRing++) 
	for(iDet=0;iDet<NDet;iDet++) { 
		fwrite(&Posx[iLayer][iRing][iDet],sizeof(FLTNBLUT),1,fPtr); 
		fwrite(&Posy[iLayer][iRing][iDet],sizeof(FLTNBLUT),1,fPtr);
		fwrite(&Posz[iLayer][iRing][iDet],sizeof(FLTNBLUT),1,fPtr);
		fwrite(&OrVx[iLayer][iRing][iDet],sizeof(FLTNBLUT),1,fPtr);
		fwrite(&OrVy[iLayer][iRing][iDet],sizeof(FLTNBLUT),1,fPtr); 
		fwrite(&OrVz[iLayer][iRing][iDet],sizeof(FLTNBLUT),1,fPtr); 
} 

(*2)
for(iLayer=0;iLayer<NLayer;iLayer++)
    for(iRing=0;iRing<NRing;iRing++) 
	for(iDet=0;iDet<NDet;iDet++) { 
		castorID = iDet + iRing*NDet + l*NRing*NDet;
}
