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 کاملLung Nodule Detection in Chest Radiographs
In the last decades, several research projects have been devoted to the development of computer-aided diagnosis (CAD) systems that could help radiologists to detect lung nodules. Despite the great effort, the problem is still open. In this dissertation, a new CAD system is presented for the detection of lung nodules in posterior-anterior chest radiographs. The lung area considered in this work ...
متن کاملNodule Detection in Postero Anterior Chest Radiographs
The use of image processing techniques and Computer Aided Diagnosis (CAD) systems has proved to be effective for the improvement of radiologists’ diagnosis, especially in the case of lung nodules detection. In this paper we describe a method for processing Postero Anterior chest radiographs which extracts a set of nodule candidate regions characterized by low cardinality and high sensitivity ra...
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 کاملHigh-speed Detection of Solitary Nodule in Chest CT Images: Cylindrical Filter and FP Reduction
A number of 2D and 3D detection methods for lung nodules in chest CT images have already been developed. Although, in general, 3D detection methods produce fewer false positives (FPs), they require a huge amount of processing. Therefore, techniques which can reduce computation time are required. In the present study, we investigate a high-speed 3D method for detecting solitary nodules in chest ...
