The effect of varying the degree of contrast and edge enhancement upon the visibility of chest lesions and anatomy was evaluated in a digital image intensifier system for chest radiography. Visual grading analysis was used as method for the evaluatio

Digital radiography of the chest was evaluated for estimation of regional ventilation disturbances. Thirty-three patients with suspected bronchial carcinomas were examined. Objective measurements of regional density changes during breathing correlate

Contrast- and edge-enhanced digital monitor images from an image intensifier system for chest radiography were compared to conventional radiograms using visual grading analysis. Eleven observers graded the visibility of rounded opacities, the carinal

Purpose: Small pulmonary subpleural nodules are sometimes difficult to localise at thoracotomy. With the advent of minimal invasive surgery, thoracoscopic resection avoiding anterolateral thoracotomy is an attractive procedure. Since this technique d

The observer performance for video monitor images presented in positive mode ('bones black') was compared to that of images presented in negative mode ('bones white') in a digital system for chest radiography based on a large image intensifier. In th

A digital system for chest radiography based on a large image intensifier was compared to a conventional film-screen system. The digital system was optimized with regard to spatial and contrast resolution and dose. The images were digitally processed
