Some aspects include a system, apparatus, means and method for configuring a radiotherapy beam shaping device to define a treatment field of view, acquiring images of a patient area within the treatment field of view based on an imaging radiation beam, determining a treatment motion model that predicts, based on the acquired images, a prediction treatment period during which the patient area will be within the treatment field of view of the radiotherapy beam shaping device, and delivering a treatment radiation beam to the patient area for a time period equal to the prediction treatment period.

Radiation treatment of moving targets

Some aspects include a system, apparatus, and method for determining that a motion of a patient area of a patient due to breathing is substantially periodic according to a treatment plan, moving a radiotherapy gantry towards a first treatment gantry angle, moving a radiotherapy beam shaping device towards a first treatment shape corresponding to the first treatment gantry angle, determining when a next treatment window is to begin based on a predictive model derived from the motion of the patient area, where the treatment window is a period of time designated for delivery of treatment radiation to the patient area according to the treatment plan, adjusting the moving of the radiotherapy gantry such that the radiotherapy gantry will reach the first treatment angle during the determined next treatment window, and delivering a treatment radiation beam to the patient area during the determined next treatment window.

The invention relates to a method and a device for generating a virtual installation model () as an image of a real installation (). As a database therefor, digital picture data () representing pictures of a real installation () on the one hand and installation components () of a component library () on the other hand are used. The data of the installation components as well as the digital picture data () of the real installation () is evaluated by means of an image analysis (). Based on this analysis, the identified installation components () are assigned to the virtually generated installation model (). The virtual image of the real installation thus created serves to document the actual structure of the installation/facility, to simplify failure analysis, e.g., in areas that are difficult to access, and/or to operate and monitor the installation/facility. In addition to geometric data, functional data, etc. of the installation components are also stored.

In a method for positioning a catheter that has been inserted into a vessel and a device for implementing the method, the road map technique is used, wherein as a mask image, a three-dimensional mask image of the vessel which is composed of number of individual mask images is employed. From these individual mask images, that individual mask image is selected whose exposure direction corresponds optimally to the exposure direction of an instantaneously captured individual image, in order to combine this selected individual mask image with the instantaneously captured mask image and to display the resulting combined image.
