Lung cancer is primary reason of death worldwide .Chances of survival increased if cancer detected at early stage. Radiologists use different imaging techniques like Conventional chest radiography, Computerized tomography to diagnose lung tumour. Out of all imaging techniques PA chest radiography involve less radiation dose, available in all diagnostic centres, so it becomes the most popular diagnosis technique for finding all chest related diseases. Due to complex anatomic structure present in PA chest radiographic image, radiologists feel difficult in finding lung tumour from the image .From past a few decades computerized diagnosis techniques were developed, for assisting radiologists in detecting tumour from PA chest radiographs. All these methods are suffering with more number of false positives. In this article we proposed a method for decreasing the number of false positive by means of suppressing ribs in the PA chest radiographic image, results of this method compared with our previously proposed nodule detection method.
