Standard plan: user selected source parameters and uniform strengths; Cimmino 1: optimize source strengths only; Cimmino 2: optimize source lengths, strengths, and template slots; and Cimmino 3: the same as Cimmino 2 with constraint for rectum. Opt 1: µ_a = 0.3 cm⁻¹, µ_s’ = 14 cm⁻¹; Opt 2: µ_a = 0.1 cm⁻¹, µ_s’ = 2 cm⁻¹. The Calculation time is obtained from a Dell PC with a 2.8 GHz Pentinum IV processor.
