Dental radiography is an essential component in the delivery of high-quality dental care for dogs and cats. During the 1980s veterinarians began taking radiographs of teeth using standard radiographic units; however, these units made patient positioning difficult and often resulted in suboptimal films. In the 1990s dental radiographic units became a more common part of the veterinary dental dia...

Digital imaging is becoming widely used in diagnostic radiology, and digital subtraction angiography (DSA) is now generally accepted [1-3]. Several studies have evaluated digital imaging using a computed radiography system for chest examinations [4-10] and for excretory urography [11] . This prospective study uses receiver operating curve analysis [12 , 13] to compare the diagnostic accuracy of...

Radiographic artifacts may mimic a clinical feature, impair image quality, or obscure abnormalities. With the development of digital radiography (DR), a new set of artifacts is introduced. Regardless of the technology, the classic technical errors that occur with film screen radiography still occur using DR. Artifacts created using computed radiography, DR, and incorrect image processing are di...

Background: The radiation doses resulting from diagnostic X-ray examinations are routinely measured in terms of entrance surface dose (ESD) and effective dose (ED). In this study, for the purpose of radiation protection, the radiation doses received from Digital chest X-ray examination were evaluated in terms of ESD and ED. Material and Methods: The ED was calculated by using the MCNP ...

While recent advances in radiologic imaging have focused on CT and MRI technology, progress in digital radiographic techniques has also had significant impact on our ability to evaluate cardiothoracic disease. A number of publications have established the improved image quality of digital imaging systems over conventional film techniques [1]. While image quality has clearly improved with digita...

Several different image processing methods are described and discussed. Their applicability to the processing of images from digital radiography equipment is compared. The overall conclusion is that advanced image enhancement methods are beneficial and can improve detectability of flaws in digital radiography images, but that these enhancement methods have to be used carefully, especially in ca...

BACKGROUND AND AIMS The aim of the present study was to compare the effect of application of an image processing mode of a colorizer on the efficacy of the detection of interproximal carious lesions viewed in direct digital radiography. MATERIALS AND METHODS A total of 102 proximal surfaces of extracted human premolars on direct digital images were evaluated by three observers with and withou...
