Abstract:
1. A radiation therapy device comprising: a radiation application apparatus that is operable to direct a therapeutic beam along a therapeutic beam center axis onto a target volume to be irradiated; a diagnostic radiation source for diagnostic x-ray radiation, the diagnostic radiation source being disposed eccentrically in relation to the therapeutic beam center axis in a rotatable manner on a rotation apparatus so that the diagnostic radiation source is operable to be rotated about the therapeutic beam center axis; and a detector for diagnostic x-ray radiation that is operable to detect the diagnostic x-ray radiation emitted from the diagnostic radiation source, wherein the radiation application apparatus is disposed on a rotatable gantry so that by rotating the gantry, a direction of the therapeutic beam center axis is changed, wherein the diagnostic radiation source is disposed in the radiation therapy device such that by rotating the gantry, the diagnostic radiation source is rotated together with the therapeutic beam center axis, and wherein the diagnostic radiation source is operable to be rotated about the therapeutic beam center axis, such that an imaging direction is changeable without rotating the gantry.
