Figure 8
Bland–Altman plots between the constrained and unconstrained analyses on Dataset A. (a) [HbO2]MSOT, (b) [Hb]MSOT, (c) [Hbtot]MSOT, (d) SO2MSOT. There is generally good agreement throughout all channels, though there appears to be a consistently lower estimate of all parameters using the constrained approach. The appearance of diagonal structure in (a–c) is due to the non-negative constraint, while the band of finite width in (d) is the result of the constrained method’s SO2 estimates being confined to [0,1]. Figure created using a combination of MATLAB and Microsoft PowerPoint.
