Abstract

For determining an inflation duration of a balloon catheter (6), a sequence of X-ray images depicting the balloon catheter (6) inside a vessel (19) of a patient (5) is received. At least one geometric parameter including a diameter (18) of the balloon catheter (6) is determined based on the sequence of X-ray images and tracked over the sequence of X-ray images. A first inflation starting time of a first inflation phase, during which the diameter (18) is increasing, is determined based on the tracked diameter (18). A first deflation starting time of a first deflation phase, during which the diameter (18) is decreasing and which lies after the first inflation phase, is determined based on the tracked diameter (18). The inflation duration is computed depending on a first time difference between the first inflation starting time and the first deflation starting time.
