1. A computer-implemented medical data processing method for determining a positional pattern of an irradiation unit for irradiating a patient with treatment radiation, the irradiation unit being part of an irradiation treatment device having an imaging device having two imaging units for generating a medical image of the patient, the method comprising executing, on at least one processor of at least one computer, steps of:
acquiring, at the at least one processor, irradiation unit position data describing irradiation unit positions of a gantry of the irradiation unit for which the imaging device has a free viewing direction onto a position of the patient, wherein the free viewing direction is a free line of sight from at least one of the two imaging units to the position of the patient, and wherein the free line of sight is not impeded by a part of the irradiation unit; and
determining, by the at least one processor and based on the irradiation unit position data, irradiation unit control data describing control signals for controlling the irradiation unit to alternately attain irradiation unit positions described by the irradiation unit position data,
wherein, in each position of two immediately subsequently attained irradiation unit positions, each of a first imaging unit of the two imaging units and a second imaging unit of the two imaging units alternate between having the free line of sight and being f impeded by at least the part of the irradiation unit, and
wherein the first imaging unit or the second imaging unit having the free line of sight is controlled to generate the medical image of the patient.
