In this paper, a new approach is presented for improving image quality. It provides a new outlook on how to apply the enhancment methods on images. Image enhancement techniques may deal with the illumination, resolution, or distribution of pixels values. Issues such as the illumination of the scene and reflectance of objects affect on image captures. Generally, the pixels value of an image is ...
The objectives of this prospective, observational study were to determine the current indications of requesting chest radiograph in sick infants in a neonatal intensive care unit (NICU) and the effect of a user-guided request form for chest radiographs of sick infants. During the three-month study period, a total of 423 chest radiographs were requested on 159 sick newborn infants in the intensi...
BACKGROUND Present guidelines recommend routine daily chest radiographs for mechanically ventilated patients in intensive care units. However, some units use an on-demand strategy, in which chest radiographs are done only if warranted by the patient's clinical status. By comparison between routine and on-demand strategies, we aimed to establish which strategy was more efficient and effective fo...
BACKGROUND The sail sign is a well-known radiographic feature of the pediatric chest. This sign can be observed in an adult population as well, but for a different reason. PURPOSE To investigate the sail sign appearing in adult chest radiography. MATERIAL AND METHODS Based on two anecdotal adult cases in which frontal chest radiographs showed the sail sign, we prospectively screened radiogr...
OBJECTIVE To compare the diagnostic performance of light emitting diode (LED) backlight monitors and cold cathode fluorescent lamp (CCFL) monitors for the interpretation of digital chest radiographs. MATERIALS AND METHODS We selected 130 chest radiographs from health screening patients. The soft copy image data were randomly sorted and displayed on a 3.5 M LED (2560 × 1440 pixels) monitor and...
