The substitution of digital representations for analog images provides access to methods for digital storage and transmission and enables the use of a variety of digital image processing techniques, including enhancement and computer assisted screening and diagnosis. Lossy compression can further improve the efficiency of transmission and storage and can facilitate subsequent image processing. ...

We have examined the radiological images used for illustration of research and case reports in this journal for the last twelve months. We have found that a number of illustrations patient’s images contained multiple patient identifiers including gender, age, date of birth and medical record number, which amount to an inadvertent breach of patient confidentiality. These are generally seen whe...

Image monitors and viewing boxes have a crucial role in the diagnostic process. Modern radiology uses different modalities to produce digital images which are to be viewed in different parts of the radiology department and throughout the hospital, sometimes simultaneously, via the Picture Archiving and Communications System (PACS). Therefore, the quality of the image monitors is of great import...

The microbiologic contamination can occur in all the steps of an intraoral conventional or digital radiographic examination, unless some measures to avoid the cross-infection are applied. Scientific articles have shown that during the radiograph taking procedure, there is contact with the patient’s oral fluids (saliva and blood) and, consequently, the contamination of the film or digital sensor...

The major challenge now facing the medical imaging community does not involve the process of imaging per se but rather the management of images once they have been acquired. Our goal with this special issue is to highlight ongoing developments in medical image management and perhaps stimulate specialists in local area networking and image database management to focus their attention on some of ...

The advent of digital imaging in radiology, combined with the explosive growth of technology, has dramatically improved imaging techniques. This has led to the expansion of diagnostic capabilities, both in terms of the number of procedures and their scope. Throughout the world, film/screen radiography systems are being rapidly replaced with digital systems. Many progressive medical institutions...

Two methods for segmentation and visualization of microcalcifications in digital or digitized mammograms are described. First method is based on modern mathematical morphology, while the second one uses the multifractal approach. In the first method, by using an appropriate combination of some morphological operations, high local contrast enhancement, followed by significant suppression of back...
