ANOTHER REVOLUTION IS taking place in radiology. This revolution differs from the previous 2 decades in which digital computers began to dominate imaging. Although the 1980s and 1990s brought us computed tomography, magnetic resonance imaging, computed radiography, digital subtraction angiography, and softcopy viewing (filmless radiology), the emphasis today is on developing seamless communicat...

Supplement 23 to Digital Imaging and Communications in Medicine (DICOM) is an introduction to the structured reporting (SR) classes, which are used for transmission and storage of clinical documents. The SR classes fully support both conventional free-text reports and structured information, thus enhancing the precision, clarity, and value of clinical documentation. In addition, the SR standard...

Medizinische Einrichtungen waren in den letzten Jahren immer wieder von Cyber-Angriffen betroffen. Auch wenn sich diese Angriffe derzeit auf die Office-IT-Infrastruktur der konzentrieren, existiert mit medizinischen Systemen und Kommunikationsprotokollen eine weitere wenig beachtete Angriffsoberfläche. In diesem Beitrag analysieren wir weit verbreiteten medizintechnischen Kommunikationsprotokol...

Radiation dose and image quality for paediatric protocols in a biplane x-ray system used for interventional cardiology have been evaluated. Entrance surface air kerma (ESAK) and image quality using a test object and polymethyl methacrylate (PMMA) phantoms have been measured for the typical paediatric patient thicknesses (4-20 cm of PMMA). Images from fluoroscopy (low, medium and high) and cine ...

BACKGROUND In magnetic resonance (MR) imaging, T1, T2 and T2* relaxation times represent characteristic tissue properties that can be quantified with the help of specific imaging strategies. While there are basic software tools for specific pulse sequences, until now there is no universal software program available to automate pixel-wise mapping of relaxation times from various types of images ...

Over the past decades, healthcare institutions adopted Picture Archive and Communication Systems in their workflows. The exchange and interaction between different equipment is performed with Digital Imaging Communication in Medicine (DICOM), which is a very extensive protocol covering many areas of the imaging laboratories. However, the communication of a wide domain composed by several medica...

Current electronic patient medical records are based on relational databases that have been very successful in managing text-based information. Recently, however, complex data types, such as digitized images, are becoming increasingly important in healthcare. Unfortunately, existing relational databases are not able to manage these complex data types in a satisfactory manner. The goal of this p...

Most of the commercial medical image viewers do not provide scalability in image compression and/or encoding/decoding of region of interest (ROI). This paper discusses a medical application that contains a viewer for digital imaging and communications in medicine (DICOM) images as a core module. The proposed application enables scalable wavelet-based compression, retrieval, and decompression of...

Currently, in radiotherapy (RT) departments, there are different manufacturers and stand-alone information systems (IS) for single-purpose applications. These systems have most of the data distributed through different IS. The DICOM-RT extension has six objects that provide a standardized way of transferring the information circulating in the external beam RT. The aim of this study is to assess...

Image classification is a most important step for image analysis. As the same in medical area especially for diagnosing the disease of the patient, classification plays a great role for the doctors to treat the patient according to the severeness of the diseases. In case of DICOM images it is very tough for optimal identification and early detection of diseases. Classification is a computationa...
