Simulated phantom for 3D reconstruction. The phantom of radius 10 mm and height 40 mm with a uniform background of μ
= 0.005mm-1 , which is positioned at x = 10mm, y = 0mm and z = 20mm. The small cylindrical anomaly has a radius of 2 mm and height 6 mm with μ
= 0.01mm-1. The anomaly is positioned at x = 15mm, y = 0mm and z = 20mm. The dashed curves represent the measurement planes, at z = 15mm, z = 20mm, z = 25mm.
