@PaulClegg can you check if these values are consistent with what Siemens has in their headers? (in particula rthe branching ratio).

@danieldeidda I cannot remember if we have any tests that check if the json files are well-formed. do You?

[danieldeidda]

We have this:

Hi both, They are similar but not identical: Kings – from dcm header isotope name :=C-11 isotope gamma halflife (sec) :=1223 isotope branching factor :=1 radiopharmaceutical :=Acetat Kings – from Scatter / Randoms / Acq radionuclide name[1] := ^11^Carbon radionuclide halflife (sec)[1] := 1221.66 radionuclide branching factor[1] := 0.9975 UoE – from dcm header isotope name :=Ga-68 isotope gamma halflife (sec) :=4062.6 isotope branching factor :=0.8891 radiopharmaceutical :=FAPI UoE – from Scatter / Randoms / Acq radionuclide name[1] := ^68^Gallium radionuclide halflife (sec)[1] := 4069.8 radionuclide branching factor[1] := 0.8768 All the best, Paul.

Thanks @PaulClegg but you had a Ge68 as well?

@danieldeidda got the other numbers from some approved reference. Who knows where Siemens got their data from. At the moment, we use our numbers and ignore the values in the header. Maybe this is worth making explicit somewhere.

[danieldeidda]

Hi, Yes the numbers in STIR are from standardised measurements. The tables are from here :http://www.lnhb.fr/accueil/donnees-nucleaires/donnees-nucleaires-tableau/

for Ge68: http://www.lnhb.fr/nuclides/Ge-68_tables.pdf

[PaulClegg]

Hi Kris, Yes - Ge-68 was used for the Kings normalisation scan. Neither halflife nor branching ratio appear in the relevant dcm file. I am not seeing anything about Ge in the .hs files produced by SIRF. All the best, Paul.

@PaulClegg I remember it was in the Siemens .s.hdr. no?

[KrisThielemans]

@danieldeidda as we cannot add a comment to JSON files, what about adding a field "data-origin" specifying the URLs that you have. I think this can be done without any code changes, but might need a change in the doc. (I can't remember if it has to be present or not). Otherwise we will forget...

[danieldeidda]

I seem to remember we had put the link in the documentation, but maybe not. Yes JSON does not seem to allow comments

[PaulClegg]

Hi Kris, The UoE NEMA scan is already in sinograms - but the radionuclide here was: isotope name:=F-18 isotope gamma halflife (sec):=6586.2 isotope branching factor:=0.9673 radiopharmaceutical:=Flutemetamol I am still trying to get team-Edinburgh to decompress the sinograms for me. The numbers above are in both the dcm and the s.dhr. All the best, Paul.

[KrisThielemans]

hmmm. you did show me a Ge-68 header...

[PaulClegg]

Hi Kris, I'm not sure what that was. Both the cardiology study and the NEMA phantom study have normalisation measurements carried out with Ge-68. I am not seeing any radionuclide characteristics in any of the files associated with these. If I stumble onto something - I will let you know! All the best, Paul.
