A radiation therapy apparatus has a multi-leaf collimator device having a pair of collimator components which respectively comprise a plurality of leaves arranged close to one another such that the leaves face one another across an irradiation axis, and configured to set a desired irradiation field by individually moving the leaves. One of the collimator components is arranged with an offset with respect to the other collimator component, within a range of a leaf-width.
