Metodos autocleavage / autotracer for three-dimensional treatment planning of radiotherapy.

摘要

It disclosed and claimed autocleavage PROCEDURE AND AUTOCONTORNEADO can be used to outline QUICKLY AND ACCURATE AND LIMITS IN AREAS SURROUNDING AREAS TO DEVELOP THAT CAN CROSS SECTIONS FOR RECONSTRUCTION linearly arranged TRIDIMENSIONAL of an image. This procedure includes AT LEAST FOUR PHASES. The first phase consists Scan A CT, MRI, or other suitable and present it in a screen. TWO-DIMENSIONAL IMAGE DISPLAY WILL INCLUDE GREYSCALE REPRESENTATIONS OF INTERNAL ORGANS AND TISSUE MASSES PLACE THE ANATOMICO through which the cross-section was made. THE SECOND PHASE IN SELECTING THE INTERIOR IS A ROI and draw a polygon WITHIN THE LIMITS OF THIS sectional view of ROI. This polygon could be drawn ALSO INSIDE a cancerous mass or other tissue ILL. The third phase of process of the present invention EXPAND POLIGONO ANALYZING A NEW WAY IN iteratively the pixels of the image on the screen, OUTSIDE THE PIXEL But alongside these subtended THAT ARE CURRENTLY IN THE POLIGONO. PIXELS be added to the polygon if the value of a function of the decision rule has a default value. POLIGONO enlargement continues until NONE OF PIXELS IN THERE site perimeter can meet the standard of decision. ONCE THIS SITUATION IS PROVEN, it is considering that the site perimeter CONSTITUTES THE BOUNDARIES ROI. THE FOURTH phase is computerizar BOUNDARIES ROI and developed an outline BASED these limits. This same procedure is repeated for Rois OTHER CAN BE SELECTED BY THE USER.
