Lung Nodule Detection on Chest CT: Evaluation of a Computer-Aided Detection (CAD) System
OBJECTIVE To evaluate the capacity of a computer-aided detection (CAD) system to detect lung nodules in clinical chest CT. MATERIALS AND METHODS A total of 210 consecutive clinical chest CT scans and their reports were reviewed by two chest radiologists and 70 were selected (33 without nodules and 37 with 1-6 nodules, 4-15.4 mm in diameter). The CAD system (ImageChecker CT LN-1000) developed ...
متن کاملA New Computer-Aided Detection System for Pulmonary Nodule in CT Scan Images of Cancerous Patients
Introduction: In the lung cancers, a computer-aided detection system that is capable of detecting very small glands in high volume of CT images is very useful.This study provided a novelsystem for detection of pulmonary nodules in CT image. Methods: In a case-control study, CT scans of the chest of 20 patients referred to Yazd Social Security Hospital were examined. In the two-dimensional and ...
متن کاملPerformance of lung nodule computer aided detection software: effect of slice thickness on chest CT
Lung cancer is the leading cause of cancer death among men and women in the United States. It is estimated that over 150,000 people die of lung cancer annually in the USA [1], and an estimated 1 million people die of lung cancer worldwide. The overall 5-year survival rate for patients with lung cancer is 15%, a number that has not changed significantly in the last 25 years. If the cancer is det...
متن کاملLung nodule detection on thoracic computed tomography images: preliminary evaluation of a computer-aided diagnosis system.
We are developing a computer-aided diagnosis (CAD) system for lung nodule detection on thoracic helical computed tomography (CT) images. In the first stage of this CAD system, lung regions are identified by a k-means clustering technique. Each lung slice is classified as belonging to the upper, middle, or the lower part of the lung volume. Within each lung region, structures are segmented again...
متن کاملA novel computer-aided lung nodule detection system for CT images.
PURPOSE The paper presents a complete computer-aided detection (CAD) system for the detection of lung nodules in computed tomography images. A new mixed feature selection and classification methodology is applied for the first time on a difficult medical image analysis problem. METHODS The CAD system was trained and tested on images from the publicly available Lung Image Database Consortium (...
