However, this enhancement technique is not very effective and does not produce a sufficiently blurred background in the image in the case of a stationary stent, such as a carotid stent, which is a thin metal mesh tube inserted into the carotid artery and expanded to Increase blood flow to areas blocked by plaques

Embodiment Construction
[0021] The present invention relates to a viewing system for detecting, locating, aligning, enhancing and scaling structures in noisy images. Here, the observation system is described by taking the application in the medical field of cardiology as an example. In applications, objects of interest are body organs such as arteries and tools such as balloons or stents. During a medical intervention called revascularization, these objects are viewed in a sequence of X-ray fluorescence images called an angiogram. It should be understood, however, that the system may be applied to other tools than stents and balloons in interventional procedures other than revascularization. For example, the object of interest may be an electrode and the organ may be the brain.
[0022] It is important that the coronary stent is fully deployed after placement at the coronary artery stenotic lesion. However, as explained above, often the stent is not always clearly visible in fluoroscopy or in expo...

A method for use in a medical viewing system for processing for display a sequence of images of a medical intervention comprising manipulating a tool such as a stent (25) within an artery. Two markers (21, 22) are provided on the tool support (10) and the method includes extracting these markers (21, 22) to yield marker location information, from which tool location information can be derived. The image of the tool within the sequence of images is then enhanced relative to the background. The background can be additionally blurred by simulating or effecting relative movement of the image detector and the stent (25) by, for example, zooming in on the stent (25) or rotating the detector relative thereto, during acquisition of the sequence of images.
Description
technical field [0001] The invention relates to a medical viewing system for displaying a sequence of images of a medical intervention involving the movement and / or positioning of a tool in a body organ. The invention also relates to a computer-executable image processing method for use in said system, and further to a medical examination device coupled to this system. The invention has application in medical fields such as cardiology for extracting, aligning and enhancing small objects of interest, such as stents. Background technique [0002] First and foremost, coronary stents are fully expanded after placement into coronary stenotic lesions. However, scaffolds are not always clearly visible in fluorescence imaging or during exposure (photography) manipulations. Improving the visibility of the stent during X-ray exposure procedures can thus help interventional cardiologists judge the clinical success of the intervention. [0003] A system and method for detection and e...
