test_Scanner gives

WARNING: Scanner Siemens Quadra: inconsistent axial block info: 320 vs 323
Error. check_consistency

an extra ring between "Vision 600" scanners? Need to do something with virtual rings then.

FYI, discussion for future work (not this PR!) in #1388

[KrisThielemans]

To get this across the line, we need to change the num_axial_crystals_per_block to be a whole "Vision 600", and add an axial virtual crystal, as discussed. I'd be eager to merge this.

Add Quadra to

STIR/src/buildblock/Scanner.cxx

Lines 1609 to 1611 in ec3a567

	case E1080:
	case Siemens_mCT:
	return 1;

Hello Kris,
I checked the code and I found the test
WARNING: Scanner Siemens Quadra: inconsistent axial block info: 320 vs 323 was resolved if

get_num_axial_blocks() * get_num_axial_crystals_per_block() == get_num_rings() + get_num_virtual_axial_crystals_per_block().
And get_num_axial_blocks() == (num_rings + get_num_virtual_axial_crystals_per_block()) / num_axial_crystals_per_block

So that, if (num_rings + num_virtual) is divisible by num_axial_crystals_per_block then the warning will be disappeared.

So rather than using 10*8 axial crytals per block, I used 10 * 8 + 1 like in mCT.

And the test passed. Please let me know your thoughts.

[KrisThielemans]

ok. Makes sense. thanks for correcting me! :-)
