Computer-aided diagnosis in chest radiography
We have developed computer-aided diagnosis (CAD) schemes for the detection of lung nodules, interstitial lung diseases, interval changes, and asymmetric opacities, and also for the differential diagnosis of lung nodules and interstitial lung diseases on chest radiographs. Observer performance studies indicate clearly that radiologists' diagnostic accuracy was improved significantly when radiolo...
متن کاملLearning techniques for Computer Aided Diagnosis in Chest Radiography
Radiologists can miss up to 30% of lung nodules (which may develop into cancer) in chest radiographs due to the background anatomy of the lungs which can camouflage the nodules. CAD helps radiologists by performing preprocessing of the images and suggesting the most likely locations for nodules. Detection of lung nodules proceeds through techniques for suppressing the background structures in l...
متن کاملComputer Aided Diagnosis in Digital Chest Radiography: Evaluation of Pulmonary Emphysema in Copd Patients
Alterations of the lung shape related to hyperinflation are regarded as indicative of emphysema. We developed and tested a computational descriptor of the shape of the lung-silhouette, as imaged in digital chest radiographs, as an objective mean to detect emphysema in patients with Chronic Obstructive Pulmonary Disease (COPD). A feature vector was extracted from the lung silhouette in lateral c...
متن کاملDevelopments in Computer Aided Diagnosis Used for Tuberculosis Detection Using Chest Radiography: a Survey
One of the major health problems of global concern is Tuberculosis (TB). According to global report of the WHO, approximately 1.3 million people, out of the 8.6 million reported, died of TB in 2012. Most of the TB deaths can be prevented if it is detected at an early stage. Hindrance to this is improper diagnosis at initial stages. Chest X ray (CXR) image is the primary medical diagnosis used f...
متن کاملComputer-aided diagnosis in chest radiography for detection of childhood pneumonia
OBJECTIVES This article presents a novel approach based on computer-aided diagnostic (CAD) scheme and wavelet transforms to aid pneumonia diagnosis in children, using chest radiograph images. The prototype system, named Pneumo-CAD, was designed to classify images into presence (PP) or absence of pneumonia (PA). MATERIALS AND METHODS The knowledge database for the Pneumo-CAD comprised chest im...
