Objective Evaluation of Radiographic Contrast- Enhancement Masks

چکیده
Several other methods of achieving dynamic range control were also discussed in the previous chapter. These methods are typically unsharp mask filters with large kernel sizes, and multi-scale approaches such as multi scale image contrast amplification (MUSICA) developed by the Agfa-Gevaert company (Vuylsteke & Schoeters, 1999). In achieving their goal of dynamic range control, these methods alter the relative contributions of spatial frequencies within the image and hence the visual appearance of the image. A full discussion of these and other image processing techniques was presented in Chapter 5.

Evaluation of Physical Tissue Compensation Filters
The prime purpose of this project was to develop and evaluate a method to digitally alter the dynamic range of digital radiographic images. This digital manipulation of the dynamic range can achieve alteration of the displayed contrast and brightness of the digital radiographic image, based on the underlying anatomy within the image. So-called anatomically shaped radiographic contrast-enhanceme...
متن کاملDevelopment of Radiographic Contrast-Enhancement Masks
Radiographic contrast-enhancement mask (RCM) algorithms were developed to overcome some limitations of general digital radiography (DR). Large attenuation differences of some anatomical regions result in exit radiation having a wide dynamic range. In general radiography, this results in anatomy not being fully visualised in the image or being displayed with suboptimal contrast. Physical tissue ...
متن کاملApplication 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...
متن کاملEnhancing Tabletop X-Ray Phase Contrast Imaging with Nano-Fabrication
X-ray phase-contrast imaging is a promising approach for improving soft-tissue contrast and lowering radiation dose in biomedical applications. While current tabletop imaging systems adapt to common x-ray tubes and large-area detectors by employing absorptive elements such as absorption gratings or monolithic crystals to filter the beam, we developed nanometric phase gratings which enable table...
