Abstract: An apparatus for providing patient selection and treatment guidance for ablation treatments, in particular renal denervation treatment, is provided which is adapted to derive, from two time series of diagnostic images indicative of two states of the patient, two dynamics measures in order to determine at least one index indicative of the relative difference between the first state and the second state. Based on the at least one index, it is possible to track the progression of the ablation treatment and determine if it has been completed. Further, the index may be used to select likely responders to the ablation treatment.

Abstract: The present invention relates to a device (10) for determining the position of stents (34, 36) in an image of vasculature structure, the device (10) comprising: an input unit (12); a processing unit (14); and an output unit (16); wherein the input unit (12) is configured to receive a sequence of images (24) of a vasculature structure (38) comprising at least one vessel branch (44, 46); wherein the processing unit (14) is configured to: detect positions of at least two markers (26, 28, 30, 32) for identifying a stent position (50, 52) in at least one of the images (24); detect at least one path indicator (64, 66, 74, 76) for the at least one vessel branch (44, 46) in at least one of the images (24) of the vasculature structure (38) at least for vessel regions in which the positions of the markers (26, 28, 30, 32) are detected; associate the at least two markers (26, 28, 30, 32) to the at least one path indicator (64, 66, 74, 76) based on the detected positions of the markers (26, 28, 30, 32) and the location of the at least one path indicator (64, 66, 74, 76); assign markers (26, 28, 30, 32) which are associated to the same path indicator (64, 66, 74, 76) to a marker group to indicate a position (50, 52) of at least one stent (34, 36) in the vasculature structure (38); and wherein the output unit (16) is configured to provide output data indicative of the positions of the markers (26, 28, 30, 32) of the marker group. The invention provides a device and a method that improve the determination of the position of stents in complicated situations.
