Abstract

Dans le cadre de la chirurgie assistée par ordinateur, le groupe VRAI, en collaboration avec l’entreprise Atracsys, est en train de développer le vTrack, un système de mesure optique 3D. Ce système repère, par triangulation, la position de marqueurs positionnés sur les outils chirurgicaux et le patient. Les marqueurs sont composés de LEDs infrarouges et communiquent par un canal sans fils avec la caméra. Le but de ce projet est, dans un premier temps, de réaliser un logiciel pour la planification de biopsie sur la base d’images scanner et ultrason. Dans un second temps, les marqueurs existants seront adaptés aux outils du radiologue. Finalement, un prototype utilisable dans un milieu hospitalier sera réalisé.

Image scanner

An image scanner—often abbreviated to just scanner—is a device that optically scans images, printed text, handwriting or an object and converts it to a . Commonly used in offices are variations of the desktop flatbed scanner where the document is placed on a glass window for scanning. Hand-held scanners, where the device is moved by hand, have evolved from text scanning "wands" to 3D scanners used for industrial design, reverse engineering, test and measurement, orthotics, gaming and other applications.

3D scanning

3D scanner is the process of analyzing a real-world object or environment to collect three dimensional data of its shape and possibly its appearance (e.g. color). The collected data can then be used to construct digital 3D models. A 3D scanner can be based on many different technologies, each with its own limitations, advantages and costs. Many limitations in the kind of objects that can be digitised are still present. For example, optical technology may encounter many difficulties with dark, shiny, reflective or transparent objects.

Barcode reader

A barcode reader or barcode scanner is an optical scanner that can read printed barcodes, decode the data contained in the barcode to a computer. Like a flatbed scanner, it consists of a light source, a lens and a light sensor for translating optical impulses into electrical signals. Additionally, nearly all barcode readers contain decoder circuitry that can analyse the barcode's image data provided by the sensor and send the barcode's content to the scanner's output port.
