Impact of ACSC corrections (combined and separate contributions) in phantom and human studies: percentage differences of the SBR measured with the Southampton method from the various reconstructions

SBR % difference contributions of AC and SC	Southampton method
	Phantom	Controls
ACSC-IRNC (impact of ACSC corrections combined)	39.4	47.7
IRAC-IRNC (impact of AC losses alone)	15.5	16.5
ACSC-IRAC (impact of SC losses alone)	24.3	31.8

Top row: the % difference between ACSC-corrected and non-corrected data is higher for controls than for phantom data. An in-depth investigation (rows 2 and 3) reveals that this discrepancy is due to SC: in fact, while the AC lead to a similar increase compared to the NC values (~16%) for both phantom and controls, the SC has a higher impact for the human controls
