[Castor-users] PET reconstruction with Staggered crystal by self-generating LUT

[赵鑫]

Dear Castor Developers and users,

I want to create a .lut and a .hscan file by running castor-PetScannerLutEx program to fitting a different system structure design with 2-layer interleaved crystal. This small animal PET system I reconstructed is named HiPET and in each detector there are 48×48 LYSO in the inner ring and 32×32 BGO in the outer ring. I edited source code:castor-PetScannerLutEx.cc in ······/castor-source/config/scanner/ , and do " cmake -> make -> make install " , and run "castor-PetScannerLutEx command". Errors occurred :

 hipet at dell-PowerEdge-T640:~/CASToR/castor-build$ castor-PetScannerLutEx -alias hipet

Generating LUT with the following alias: hipet... 

>>> Start writing binary LUT file for layer #0...
>>> Binary LUT writing OK
***** oMatrix::Multiplication()-> Not matching number of colons and lines of the two matrices !
