1. A radiation imaging apparatus comprising:
a main rotatable arm that is configured to rotate around a first pivot relative to a device for pivotably holding the main rotatable arm;
a first arm rotatably attached to one side of the main rotatable arm to rotate about a second pivot, the first arm holding a imaging device;
a second arm rotatably attached to an other side of the main rotatable arm to rotate about a third pivot, the second arm holding a radiation source, a radiation axis of the radiation source is configured to irradiate an imaging plane of the imaging device; and
a linking means that links a rotation of the first arm to the rotation of the second arm such that a rotation of the first arm causes a rotation of the second arm and vice versa in opposite rotational directions for adjusting a source image-receptor distance,
wherein the linking means includes a linking mechanism rotatably attached to the first arm at a pivot point of the first arm and rotatably attached to the second arm at a pivot point of the second arm, the linking mechanism extending between the pivot point of the first arm and the pivot point of the second arm, the linking mechanism mechanically linking a rotation of the first arm with a rotation of the second arm for causing the opposite rotational directions for adjusting the source image-receptor distance.
