Automatic movement detection

A method for automatic detection of an event in which a device is leaving a stable position relative to and within an anatomy, the method comprising the steps of:

• receiving a sequence of fluoroscopic images,
• detecting the device in at least two of the fluoroscopic images,
• determining a motion field of the detected device in the sequence of fluoroscopic images,
• generating a sequence of integrated images by integrating the sequence of fluoroscopic images taking into consideration the motion field,
• determining a saliency metric based on the integrated images,
• identifying a landmark in the integrated images based on the saliency metric, wherein said method further comprises the steps of:
• visualizing at least one fluoroscopic image out of the sequence of fluoroscopic images together with a roadmap as an overlay of the roadmap on the at least one fluoroscopic image;
• and
• masking the roadmap when a motion of the landmark relative to the device is determined.
