OBJECTIVES This study evaluated the agreement of computed tomography (CT) imaging using 3D reformations (3DR) with shaded surface display (SSD) and maximum intensity projection (MIP) in the diagnosis of bone changes in mandibular condyles of patients with rheumatoid arthritis (RA), and compared findings with multiplanar reformation (MPR) images, used as the criterion standard. MATERIAL AND ME...

The number of computed tomography examinations has continuously increased over the last decades and accounts for a major part of the collective radiation dose from medical investigations. For purposes of quality assurance in modern radiology a systematic monitoring and analysis of dose related data from radiological examinations is mandatory. Various ways of collecting dose data are available t...

This paper describes an authoritative, non-proprietary information resource that provides an efficient mechanism for embedding specialized clinical knowledge into the design of healthcare telecommunications systems. The resource marries two types of data interchange standards, a message/electronic-document standard and a terminology standard. In technical terms, it is part protocol and part dat...

To meet the demand for high speed transmission of image, efficient image storage, remote treatment an efficient image compression technique is essential. Wavelet theory has great potential in medical image compression. Most of the commercial medical image viewers do not provide scalability in image compression. This paper discusses a medical application that contains a viewer for digital imagin...

The hybrid navigation technique involves the merging of Dynamic (DN) system (Navident, Claronav, Canada) and static (3Shape, Copenhagen, Denmark). Combining advantages both techniques, devising a protocol will be advantageous to eliminate difficulties faced by operators in using either methods separately. Three patients requiring dental implants were included this study. This requires cone beam...

The PACS system built and used in hospitals nowadays has quite significant overload on its central server because of both treatment of very large data and full management of medical images. We suggest a distributed communication and management methodology using PC to PC multicasting strategy for efficient management of medical images produced by DICOM modalities. It is absolutely necessary for ...

Digital Imaging and Communications in Medicine (DICOM) is a standard used for distribution and viewing of medical images from different modalities. In this paper, we propose a method for compressing DICOM images based on the well-known Set Partitioning in Hierarchical Trees (SPIHT) which possess the progressive transmission capabilities useful for telemedicine applications. This is in sharp con...

In the medical fields, images and reports of patients are increasingly being held in a digital form. To overcome the problem of heterogeneity due to the use of different devices between the various specialties, DICOM SR standard (Digital Imaging and Communications in Medicine for Structured Reporting) has emerged. For the medical imaging community taking advantage of this standard to improve me...

Background: Nowadays, image de-noising plays a very important role in medical analysis applications and pre-processing step. Many filters were designed for image processing, assuming a specific noise distribution, so the images which are acquired by different medical imaging modalities must be out of the noise. Objectives: This study has focused on the sequence filters which are selected ...
