I've tried and failed at testing each of the following:

mCT LM data

lm_to_projdata fails - "CListEventECAT8_32bit can only handle axial compression==1" https://github.com/UCL/STIR/blob/59ab3eadadfe514fa5d4a823a6db305c9193567a/src/listmode_buildblock/CListRecordECAT8_32bit.cxx#L43-L46 This is regardless of the template used. The issue is that the LM data itself, as far as I can tell, is encoded with span 11. (I think I recall this being due to the number or LORs and fitting into 32 bits, I heard you can acquire uncompressed with 64 bit LM?)

Does this mean we need to support axial compression in this class?

mCT Sino data

I've tried here my own data and data supplied by @Ede1994. These are compressed though, and I've tried and failed to use Siemens' intfcomr.exe to uncompress without success. Any hints here would be greatly appreciated:

The first file reports a data corruption, which could be possible and unfortunate I guess. The second file runs, and takes some time, but not output file is to be found.

Vision 600 LM data

Using @NicoleJurjew 's data This one has be a bit stumped: I'm running into: "ERROR: construct_proj_data_info: span -1 has to be larger than 0" when calling lm_to_projdata. This happens even when calling with a "dummy" template sinogram, and I believe is before loading the template, so it is coming from the loading of the LM data.

Full error:

Which is coming from https://github.com/UCL/STIR/blob/59ab3eadadfe514fa5d4a823a6db305c9193567a/src/buildblock/ProjDataInfo.cxx#L409-L410 But I haven't yet worked out where this is called from or what is causing STIR to set span=-1. It looks like this is used as a default "unset" value in a few places...

Actually... Now that I write this out I notice that the mCT LM interfile had the following keys:

%axial compression := 11
%maximum ring difference := 49
%number of projections := 400
%number of views := 168
%number of segments := 9
%segment table := { 109, 97, 97, 75, 75, 53, 53, 31, 31 }

I guess these may have been necessary for STIR...

Update for the Vision 600:

I had to add %axial compression := 1 to the Vision LM data - but it seems this isn't in there by default.

Now a new problem is working out the layout of the singoram, described in 6.3.1 here: https://link.springer.com/chapter/10.1007%2F978-3-030-43040-5_6

This is definitely for another PR! Lets get the mCT working and test with that...

ashgillman avatar Aug 17 '21 06:08 ashgillman

This PR should be closed. I'm not sure how much of this should be merged onto the normal TOF PR #304. Better to do that soon, or create a new PR to #304.

KrisThielemans avatar Jan 03 '22 14:01 KrisThielemans

This is now obsolete. Siemens things have been added to the normal TOF PR. Note that mCT list data still won't be handled there due to the axial compression.
