Application of Radiographic Contrast-Enhancement Masks in Digital Radiography
ثبت نشده
چکیده
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 RCMs enhance the displayed contrast in specific areas of the image, whilst leaving other areas unaffected. The overall effect is to reduce the dynamic range of the DR image while maintaining high subject contrast within the image.

Development 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 کاملEvaluation 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 کاملQuality comparison of direct digital panoramic radiography and computed radiography panoramic
BACKGROUND AND AIM: Digital panoramic X-ray images can be captured using photostimulable phosphors or solid-state detectors (i.e. charge-coupled devices and Flat-Panels). The first category is defined as computed radiography (CR) or semi-direct radiography. The second technology that uses solid-state detectors is known as direct digital radiography (DDR). Both of these technologies have their o...
متن کاملAgreement of Digital Panoramic Radiographs with and without Software Enhancement in the Diagnosis of roximal Dental Caries in Primary Molars
Introduction: Dental caries is the most common chronic condition in children. Recently, there has been a growing tendency to using digital panoramic radiography among clinicians. The present study aimed to determine the accuracy of digital panoramic radiography with and without software enhancement in the diagnosis of proximal dental caries in primary molars. Methods: This study was conducted u...
