a T1-w sequence (3D-VIBE) of the model's eye illustrating the tumor area in the ciliary body at 12 o'clock position (arrow). b T2-w sequence (3D-VIBE) of the model's eye cannot delineate the tumor area from the surrounding healthy tissue. c Four ROIs obtained from the relative eye segments and one ROI obtained from the image background for the noise estimation. AC, anterior chamber; SCB, superior area of the ciliary body; ICB, inferior area of the ciliary body; VH, vitreous humor; Bg, background.
