In this work we present the development of an electronic teaching file (ETF) system. The proposed system is accessible through a standard web-browser, allowing users to perform a variety of tasks, including data entry, dataset quality control, and image visualization. In addition, it is a modular and extensible web-based clinical information management system that integrates features of multimodality and multi-center studies. This integration has been done by using MIRCRSNA schemas and application programming interfaces. The system has provided a secure and user-friendly platform to archive and use a comprehensive set of medical images and related information.
Learning radiology requires systematic and comprehensive study of a large knowledge base of medical images. In this
work is presented the development of a digital radiology teaching file system. The proposed system has been created in
order to offer a set of customized services regarding to users' contexts and their informational needs. This has been done
by means of an electronic infrastructure that provides easy and integrated access to all relevant patient data at the time of
image interpretation, so that radiologists and researchers can examine all available data to reach well-informed
conclusions, while protecting patient data privacy and security. The system is presented such as an environment which
implements a distributed clinical database, including medical images, authoring tools, repository for multimedia
documents, and also a peer-reviewed model which assures dataset quality. The current implementation has shown that
creating clinical data repositories on networked computer environments points to be a good solution in terms of providing
means to review information management practices in electronic environments and to create customized and contextbased
tools for users connected to the system throughout electronic interfaces.
The task of analyzing and comparing different algorithms, methods and applications through sound testing is an essential
qualification of algorithm design. A great limitation of image processing algorithm development lies in the difficulty to
assess exhaustively the software, or at least, using a large and diverse number of cases for comparison. This work
addresses a distributed and multicentric approach for medical image database environment and its implementation. The
purpose is to design and make available a free, online, multipurpose and multimodality medical image database system.
This database should include comprehensive, "hard" and unusual cases and be regularly updated with new imaging
protocols, new modalities data from various clinical applications. These set of peer-reviewed data can be used in
This work presents the development of an electronic infrastructure to make available a free, online, multipurpose and multimodality medical image database. The proposed infrastructure implements a distributed architecture for medical image database, authoring tools, and a repository for multimedia documents. Also it includes a peer-reviewed model that assures quality of dataset. This public repository provides a single point of access for medical images and related information to facilitate retrieval tasks. The proposed approach has been used as an electronic teaching system in Radiology as well.
Due to increasing number of digital images used in medical diagnosis, the image processing and analysis are becoming
essential for many tasks in medicine. One of the obstacles within the field of medical image processing is the lack of
reference image datasets freely available for groups and/or individual users, in order to evaluate their new methods and
applications. In order to improve this situation, this work presents the development of a framework to make available a
free, online, multipurpose and multimodality medical image database for software and algorithm evaluation. The project
is implemented as a distributed architecture for medical image database including a publishing workflow, authoring tools,
and role-based access control. Our effort aims to offer a testbed and a set of resources including software, links to
scientific papers, gold standards, reference and post-processed images, enabling the medical image processing
community (scientists, physicians, students and industrials) to be more aware of evaluation issues. The proposed
approach has been used as an electronic teaching system in Radiology as well.

We have implemented a distributed architecture for medical image database, including authoring, storage, and repository for documents and image processing software.

Our focus of development was on convenience and easy of use of a generic system adaptable to different contexts.
With the advent of the digital devices for medical diagnosis the use of the regular films in radiology has decreased. Thus, the management and handling of medical images in digital format has become an important and critical task. In Cardiology, for example, the main difficulty is to display dynamic images with the appropriated color palette and frame rate used on acquisition process by Cath, Angio and Echo systems. In addition, other difficulty is handling large images in memory by any existing personal computer, including thin clients. In this work we present a web-based application that carries out these tasks with robustness and excellent performance, without burdening the server and network. This application provides near-diagnostic quality display of cardiac images stored as DICOM 3.0 files via a web browser and provides a set of resources that allows the viewing of still and dynamic images. It can access image files from the local disks, or network connection. Its features include: allows real-time playback, dynamic thumbnails image viewing during loading, access to patient database information, image processing tools, linear and angular measurements, on-screen annotations, image printing and exporting DICOM images to other image formats, and many others, all characterized by a pleasant user-friendly interface, inside a Web browser by means of a Java application. This approach offers some advantages over the most of medical images viewers, such as: facility of installation, integration with other systems by means of public and standardized interfaces, platform independence, efficient manipulation and display of medical images, all with high performance.
The goal of the current study is to describe the experience of the Heart Institute (InCor) in the implementation of a patient-oriented Hospital Information System (HIS) integrated with the Radiology Information System (RIS) and the Picture Archiving and Communication System (PACS) in an open-source three-tier architecture. The system was designed in modules that permits patient admission, discharge and transfer (ADT), registration of medical activities, registration of diagnoses and therapy, order entry and access of all patient data, including vital signals, images and lab tests. The modules are integrated in a single Web-based application allowing easy and fast navigation through the application. In order to provide high quality of patient care in an efficient and cost-effective manner, thin clients workstations in a Linux environment were used. To access the patient information users have to perform an authentication procedure that uses LDAP protocol, which also defines a profile to the users. The system is fully integrated to the InCor's PACS, allowing instant access to the image database from applications that requires this information, such as diagnostic reports. For displaying the images a Java DICOM viewer was implemented. On the server side, a Java DICOM server was designed to allow communication with all DICOM modalities.
