Abstract

The present invention relates to Intraluminal device guidance with minimized X-ray dose. In order to provide further dose reduction while solving the conflict of objectives to not impair guidance during intravascular interventions, a control device (10) for intraluminal device guidance with minimized X-ray dose is provided. The device comprises a data input 12, a data processor 14 and an output interface 16. The data input is configured: to provide an X-ray image (18) of a vascular structure with an inserted device having at least one distinctive feature identifiable in the X-ray image. The X-ray image is acquired with a primary radiation characteristic. The data processor is configured: to determine a signal to noise ratio relating to an image portion comprising the at least one distinctive feature; to compute a secondary radiation characteristic for acquiring secondary X-ray images with the secondary radiation characteristic to generate images for further guidance of the inserted device; and to select the primary radiation characteristic or the secondary radiation characteristic for acquiring further X-ray images. The selecting is dependent on at least one of the parameters comprising: current location within subject and current treatment phase. The output interface is configured: to provide the selected radiation characteristic for acquiring further X-ray images.
