Long line positioning in neonates: does computed radiography improve visibility?
OBJECTIVES To assess the use of soft copy reporting of computed radiography (CR) images in determining intravenous long line tip position in neonates and compare visibility rates with hard copy printed images. METHOD A retrospective study of all long lines inserted on the neonatal unit over a period of one year was performed. Forty five lines were inserted in 30 neonates over this time. Asses...
متن کاملEndobronchial Tuberculosis and Chest Radiography
Endobronchial tuberculosis and chest radiography I read, with interest, the article entitled “Clinical and Para-clinical Presentations of Endobronchial Tuberculosis” by Ahmadi Hoseini H. S. et al. (1) published in this journal. I would like to focus on some details about the chest X-ray of patients as elaborated by the authors in the results section. Accordingly, the findings of chest radiograp...
متن کاملNeonatal chest computed radiography: image processing and optimal image display.
OBJECTIVE The purpose of this study was to determine soft-copy image display preferences of brightness, latitude, and detail contrast for neonatal chest computed radiography to establish a baseline for future work on low-dose imaging. CONCLUSION Observers preferred brighter images with higher detail contrast and narrow to middle latitude for soft-copy display compared with the typical screen-...
متن کاملApplication of off‐line image processing for optimization in chest computed radiography using a low cost system
The objective of this study was to improve the visibility of anatomical details by applying off-line postimage processing in chest computed radiography (CR). Four spatial domain-based external image processing techniques were developed by using MATLAB software version 7.0.0.19920 (R14) and image processing tools. The developed techniques were implemented to sample images and their visual appea...
متن کاملOptimization of Dose and Image Quality in Full-fiand Computed Radiography Systems for Common Digital Radiographic Examinations
IntroductionA fine balance of image quality and radiation dose can be achieved by optimization to minimize stochastic and deterministic effects. This study aimed in ensuring that images of acceptable quality for common radiographic examinations in digital imaging were produced without causing harmful effects. Materials and MethodsThe study was conducted in three phases. The pre-optimization inv...
