Inspired by previous approaches on contrast agent detection, we propose a learning-based framework which is able to classify contrasted frames more robustly than previous methods, Furthermore, we performed a quantitative evaluation on a clinical data set consisting of 34 angiographies. Our learning-based approach reached a classification rate of 79.5\%. The beginning of a contrast injection was detected correctly in 79.4\%.}, language = {en} } @misc{WuChenStrobeletal., author = {Wu, W. and Chen, T. and Strobel, Norbert and Comaniciu, D.}, title = {Method and system for ablation catheter and circumferential mapping catheter tracking in fluoroscopic images (Patent, US 9,002,436)}, language = {en} } @misc{BarbotKiralyStrobel, author = {Barbot, Julien Christian and Kiraly, Atilla Peter and Strobel, Norbert}, title = {Localization and tracking of cryo-balloon during interventional fluoroscopy imaging (Patent, US 8989463B2)}, abstract = {A method for the detection of a balloon catheter within a fluoroscopic image, including: removing noise from a fluoroscopic image; detecting edges of a balloon catheter in the fluoroscopic image, wherein the detected edges include subsets of connected edges; extracting an edge subset from the subsets of connected edges; fitting a model to the extracted edge subset; removing outliers of the extracted edge subset based on the fitting of the model; adding the extracted edge subset without the outlier to a data set; repeating the extracting, fitting, removing and adding steps for the remainder of the subsets of connected edges; and fitting the model to the data set, wherein the data set is indicative of the balloon catheter.}, language = {en} }
