Abstract
The present invention relates to providing a projection data for providing a guidance image. In order to provide an enhanced guiding image technique for generating a guidance image of the patient's anatomy to be projected on the body surface of the patient, such that a at least a basis for a corrected guidance image for a better correlation to the patient's current motion can be provided, in particular to the patient's current breathing motion state, a device (10) for providing a projection data set is provided that comprises a storage means (12), an input interface (14), a processing unit (16) and an output interface (18). The storage means is configured to store a pre-determined basis data set representing a 3D tomographic image of a subject (20). The input interface is configured to receive reference data representing a current spatial depiction at least of a target region (22) of the subject. The processing unit is configured to register the reference data on the pre-determined basis data set. The processing unit is further configured to transform, based on the reference data and the result of the registration, the pre-determined basis data set resulting in a working data set r…
