DEVICE AND METHOD FOR AUTOMATIC DETECTION OF A SURGICAL TOOL ON AN IMAGE PROVIDED BY A MEDICAL IMAGING SYSTEM

摘要

The invention relates to a method for detecting a surgical tool on a first image comprising the following steps: storing shape parameters of the surgical tool; determining a second image (I3) containing distinct pixel regions from the first image by a first process including segmenting the first image; determine first windows (F), each first window surrounding one of the regions; selecting at least a second window among the first windows from the shape parameters; determining a third image from the first image by applying to the first image a second processing implementing the Frangi algorithm; and determining lateral edges of the surgical tool on the portion of the third image contained in said second window
