In this study we present an efficient image categorization system for medical image databases utilizing a local patch representation based on both content and location. The system discriminates between healthy and pathological cases and indicates the subregion in the image that is automatically found to be most relevant for the decision. We show an application to pathology-level categorization ...

Digital radiography has become an indispensable diagnostic tool in dentistry today. To improve vision and diagnosis, dental x-ray software allows image enhancement (eg, adjusting color, density, sharpness, brightness, or contrast). Exporting digital radiographs to a file format compatible with commercial graphic software increases chances that information can be altered, added, or removed in an...

PURPOSE To evaluate the usefulness of a commercially available computer-aided diagnosis (CAD) system that incorporates temporal subtraction for the detection of solitary pulmonary nodules on chest radiographs by readers with different levels of experience. MATERIALS AND METHODS Sixty pairs of chest radiographs in 30 patients with newly detected solitary pulmonary nodules and 30 normal cases, ...

In underdeveloped nations, severe lower respiratory infections are the principal reasons of infant mortality. The best treatments and early diagnosis now being used to alleviate this issue. developing better treatment prevention approaches still required. Clinical, microbial, radiographic clinical studies have a broad range applicability within across populations, it much depends on knowledge r...

Fatal pulmonary cement embolism is the worst complication after balloon kyphoplasty. Therefore the authors conducted a prospective study about the use of postoperative plain radiographs of the chest as a screening tool for the detection of pulmonary cement embolism. More specifically, they tried to determine its incidence. Postoperative AP and lateral plain radiographs of the chest confirmed th...

OBJECTIVE A massive-training artificial neural network is a nonlinear pattern recognition tool used to suppress rib opacity on chest radiographs while soft-tissue contrast is maintained. We investigated the effect of rib suppression with a massive-training artificial neural network on the performance of radiologists in the detection of pulmonary nodules on chest radiographs. MATERIALS AND MET...
