The invention concerns 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 (I) containing distinct pixel regions from the first image by means of a first processing operation comprising the segmentation of the first image; determining first windows (F), each first window surrounding one of the regions; selecting at least one second window from 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 operation implementing Frangi's algorithm; and determining lateral edges of the surgical tool on the part of the third image contained in said second window.

Device and method for automatically detecting a surgical tool on an image provided by a medical imaging system

The invention concerns an analysis method for a surgical operation via endoscopy performed at an operative site in a volume located inside the body of an animal, characterized in that it comprises the steps consisting of:

System and method for analysing a surgical operation by endoscopy

The invention relates to an endoscopic imaging system for observation of an operative site () inside a volume () located inside the body of an animal, comprising:

Imaging system for three-dimensional observation of an operative site

The invention concerns an imaging system to monitor at least one surgical instrument in an operative site inside a volume of the body of an animal, comprising: at least one endoscopic camera to obtain endoscopic data on the operative site, at least one ultrasound imaging device to obtain ultrasound data on the operative site, and a processing device to process the endoscopic and ultrasound data. The imaging system further comprising at least three markers intended to be positioned in the operative site, said markers being mobile relative to the instrument, each marker being adapted to be detected both by the endoscopic camera and by the ultrasound imaging device, so as to permit cross-mapping of the endoscopic and ultrasound data by the processing means.

Imaging system for following a surgical tool in an operation field

A device for detecting a surgical tool in an image, the surgical tool going through an incision made in a patient's skin or one of his organs, the device including: means for storing shape parameters of the surgical tool. means for determining the position of the projection of the incision in the image plane and means for determining points and/or straight lines characteristic of the projection of the surgical tool on the image based on the shape parameters and on the position of the projection of the incision.
