Pearson correlation coefficients (r), p values and coefficient of variation for EDV, ESV, SV and EF between our interventional system and the two commercially available techniques

	Interventional system versus CVI42				Interventional system versus TomTec
	EDV (ml)	ESV (ml)	SV (ml)	EF (%)	EDV (ml)	ESV (ml)	SV (ml)	EF (%)
Pearson Corr.	0.980	0.984	0.996	0.993	0.723	0.755	0.639	0.665
p values	$1.{013}^{-12}$	$1.{950}^{-13}$	$7.{339}^{-18}$	$1.{6184}^{-16}$	0.0120	0.0073	0.0343	0.0256
CoV (%)	0.173	0.310	0.896	0.943	8.277	11.038	11.066	11.091

In total 16 patients and 3 volunteers were processed for the comparison between our interventional system and circle CVI42 and 11 patients were processed for the comparison between our interventional system and TomTec software
