摘 要：Pleural thickenings as biomarker of exposure to asbestos may evolve into malignant pleural *** diagnosis is based on a visual investigation of CT images,which is a time consuming and subjective *** image processing system identifies the pleural contours and detects pleural *** two algorithm steps,namely the detection of the thorax and the removal of air and trachea,3D morphological operations were implemented and tested,in order to find an optimum of its application in the aspect of calculation expense and *** an evaluation,we obtained an experimental optimum for both algorithm steps.
