Radiographic Contrast-Enhancement Masks in Digital Radiography

Application of Radiographic Contrast-Enhancement Masks in Digital Radiography

In this project RCMs were applied to all these regions listed in Table 7.1 with the exception of the chest region. Examples of images with and without RCM are provided and discussed in this chapter. Appropriate and inappropriate use of factors that alter RCMs is also discussed, together with a comparison of RCM and other techniques used for dynamic range control. Specifically applied digital RC...

A Phantom Study for the Optimization of Image Quality and Radiation Dose for Common Radiographic Examinations in Digital Radiography

Introduction: Phantom studies facilitate the implementation of radiation dose surveillance as a function of radiographic technical parameters for minimizing patient radiation dose. The evidence of such investigations can then be used to evaluate technical parameters used in the radiographic procedures to reduce radiation dose without compromising the image quality. Material and Methods: This ex...

Optimization 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...

Digital radiography enhancement by nonlinear multiscale processing.

Today's digital radiography systems mostly use unsharp maskinglike enhancement algorithms based on splitting input images into two or three frequency channels. This method allows fine detail enhancement as well as processing of global contrast (harmonization). However, structures of medium size are not accessible. In extension of a standard algorithm of such type, we develop and test a new enha...
