(A) CT volumetric rendering of the irradiated volume in blue, the animal brain volume in pink, the eye in green (right) and red (left), and the two microbeams radiotherapy (MRT) ports within the black dotted lines. Checkered insets: For each port, a radiosensitive mask that was aligned to the MRT beam is shown; spatial orientation defined by A: anterior, P: posterior, R: right, L: left, V: ventral, and D: dorsal. (B) Anatomical MRI visualization (axial and horizontal orientations, before Gd-DOTA injection) of the targeted caudate nucleus (Cd) edged by white dotted line and, with an additional 2-mm border, the irradiated volume in blue dotted line and the two MRT ports within the black dotted lines. IC: insular cortex of both hemispheres was on the trajectory of the MRT ports.
