DETECTION A PLEURAL EFFUSION OF THORACIC WITH NEURAL NETWORK BACKPROPAGATION METHOD BY FEATURE EXTRACTION BINARY

Abstract

In normal condition the pleural cavity containing 5 ml to 20 ml of fluid. This liquid will be used as lubricants in the process of respiration take place.If the increased accumulation of fluid in the pleural cavity , indicating the presence of a disease called pleural effusion.Pleural effusionincreased accumulation will push the heart position , making it difficult patients to breathe. Difficult of distinguish the excess fluid in the pleural cavity and normal fluid boundary in the pleural cavity is to be minimized by a doctor of radiology. This study is important because it aims (due to) to detect lung pleural effusion with Artificial Neural network method (ANN) back propagation through the binary feature extraction that reduce future physicians in the treatment of patient’s doubts.. Binary feature extraction is obtained from the level set segmentation. The process of image enhancement by histogram equalization and contrast enhancement must be done before the contrast level set segmentation process.. Characteristic binary pattern trained of ANN tissue taken from 5% to 25% in sinus costophrenicus angle image of the thorax.Neural network can recognize the characteristic patterns of the binary feature 15% are well trained. Validation ANN pattern recognition by up to 100%, while process of testing the ANN is able to identify 14 data from 15 test data to test validation value reaches 93.33% on the condition of setting 2 hidden layers, each of hidden layer contain 10 neurons.
