Detection of Pulmonary Nodules in ct Images Using Deep Learning Technique

Abstract

Lung Cancer is one of the most deadly diseases worldwide. According to the American Cancer Society, about 234,030 peoples have been suffering from lung cancer. It can be cured if it is diagnosed earlier which decreases the death rate. A computational diagnostic tool named Computer Aided Diagnosis (CAD) is used to detect pulmonary nodules. Extensive work has been made in this domain. However, previous Computer Aided Diagnosis (CAD) system are time-consuming since they needed more modules such as image modification, segmentation and the features should be extracted by the domain experts to build the entire CAD system. It is hard to examine large data using the existing CAD system. Thus, a novel framework with a Convolutional Neural Network (CNN) to detect pulmonary nodule is proposed. Firstly, a preprocessing technique named bilateral filtering is applied to increase the image quality and remove the irrelevant noise from the Computer Tomography (CT) images. Secondly, the preprocessed data are trained into a convolutional neural network to detect the nodule and classify it. The performance of this system is validated using the Lung Image Database Consortium (LIDC) dataset. The accuracy of nodule candidate detection achieves 93%. It states that the proposed method achieves better accuracy in nodule detection.

Intelligent Diagnosis of Lung Cancer Using Deep Learning

“…There are different types of cancer, and lung cancer is one of the most dangerous and common types. According to the American cancer society, 234,030 people have lung cancer [2]. Persons.…”

“…They are identifying nodules in CT scan images are complex, because nodules can resemble other visible tissues in the images. For example, in Fig If lung cancer is diagnosed early, the death rate of affected patients will be decreased [2]. The problem of lung cancer diagnosis is due to the reasons mentioned earlier; it is of significant importance in saving human lives.…”
