Cube Navigation System comprising of planning software shown on the computer screen on the left and scannable cube on the right. The software is displaying a lumbar infiltration with coronal, sagittal, and axial views, while the yellow line in the top right and bottom left view represents the virtual needle. The entry holes calculated from the virtual needle trajectory are indicated on the bottom right quadrant as green dots marking where the physical needle should be inserted on the top and bottom plates of the Puncture Cube in order to replicate the path of the virtual needle.

Based on a modified 3D multiplanar reformation (MPR) view, the interventionalist chose the target and could freely shift the path of a virtual needle from the target through the Puncture Cube (Figure 1C).

Periradicular infiltration of the L5 nerve root on the right. (A) On the upper right of the scan, the outline of the Puncture Cube is visible. It is fixed on the patient using the flexible pre-mounted self-adhesive tape. It is impossible to reach the L5 nerve root (asterisk) in the gantry plane. (B) Puncture planning with the virtual needle in craniocaudal angulation: the virtual needle is represented by the yellow dot in the top left quadrant and yellow line in the top right and bottom left quadrants. Coordinates for the Puncture Cube are represented in the bottom right quadrant by the green dots. (C) MPR reconstruction along the introduced needle (craniocaudal angulation) shows the now simple access path. The outline of the collapsed Puncture Cube is visible. (D) Sagittal MPR reconstruction along the needle path shows the angulation of the needle.

The Puncture Cube was detected relative to the patient in the planning scan using Synedra software (Synedra information technologies GmbH, Innsbruck, Austria), and a virtual model of the cube was superimposed over the scanned Puncture Cube (Figure 2).
