| 1. A radiographic device comprising:
a base;
a support arm pivotably coupled to the base and defining a support axis, the support arm being movable between a normal position
and two diametrically opposed, laterally rotated positions;
a radiographic head coupled to the support arm;
a tension assembly coupled to the base; and
a linkage system extending between the tension assembly and the support arm, the linkage system including:
a hub rotatably coupled to the base and defining a center of rotation with which a lateral reference line intersects;
a linkage partially entrained with the hub and having a proximal end adapted for coupling to the support arm and a distal
end adapted for coupling to the tension assembly, the linkage including a pivot point joining the linkage proximal end and
the linkage distal end;
wherein, when the support arm is in the normal position, the linkage is positioned with respect to the hub so that the lateral
reference line also intersects the linkage pivot point.
