H K Huang 《Radiographics》1992,12(1):131-139
A picture archiving and communication system (PACS) is a system integration of many components, including radiologic image acquisition devices, computers, communication networks, image display workstations, and data base management systems. The author describes three general approaches to implementing a PACS. In the first approach, the department or institution acts as a systems integrator, designing and implementing the PACS. In the second approach, the PACS is planned on the basis of the department's operations and environment and then a manufacturer is contracted to design and build the system. The third approach is to purchase a turnkey system, with some modifications provided by the manufacturer for a specific clinical application. The author provides examples of each approach in the clinical environment and presents the disadvantages and advantages of each.  相似文献

A computer system that improves the quality, user-friendliness, accessibility, and management of radiology data (images, reports, databases, knowledge) was implemented at a private institute. A picture archiving and communication system (PACS) was integrated with the radiology information system (RIS). Two servers and 12 personal computers form the integrated system. The first server is dedicated to management and archiving of Digital Imaging and Communications in Medicine (DICOM) images. The second server is dedicated to management of the RIS and archiving of patient data (Structured Query Language database), reports (hypertext markup language [HTML]), and images in the Joint Photographic Experts Group (JPEG) format (mini-PACS). There are three main client-server networks: a common network of imaging modalities (magnetic resonance imaging, computed tomography, ultrasonography, digital radiography) and two fast Ethernet networks (the PACS network and the RIS network). The RIS-PACS is linked remotely with other workstations and servers via Integrated Services Digital Network (ISDN). Images and reports can be distributed to referring physicians in the form of multimedia HTML and JPEG documents, which can also be used for quick and easy archiving, distribution, and reviewing within the institute. However, referring physicians have been reluctant to use electronic reports and images.  相似文献

Introduction New information technologies offer the possibility of major improvements in the professional education and advanced training of physicians. The web-based, multimedia teaching and learning application Schoolbook has been created and utilized for neuroradiology.Methods Schoolbook is technically based as a content management system and is realized in a LAMP environment. The content is generated with the help of the developed system and stored in a database. The layout is defined by a PHP application, and the webpages are generated from the system.Results Schoolbook is realized as an authoring tool so that it can be integrated into daily practice. This enables the teacher to autonomously process the content into the web-based application which is used for lectures, seminars and self-study. A multimedia case library is the central building block of Schoolbook for neuroradiology, whereby the learner is provided with original diagnostic and therapeutic data from numerous individual cases. The user can put individual emphasis on key learning points as there are various ways to work with the case histories. Besides the case-based way of teaching and learning, a systematically structured way of dealing with the content is available.Conclusion eLearning offers various opportunities for teaching and learning in academic and scientific as well as in economic contexts. Web-based applications such as Schoolbook may be beneficial not only for basic university education but also for the realization of international educational programmes such as the European Master of Medical Science with a major in neuroradiology.  相似文献

We describe a method of converting postprocessed functional MR images to the Digital Imaging and Communications in Medicine (DICOM) standard and sending these DICOM images directly into any picture archiving and communication system (PACS) or stand-alone DICOM database. This method provides system-wide access and archiving of previously research-only applications, it permits the clinical review of postprocessed data on DICOM-compliant workstations, and it can be used to move functional MR data onto intraoperative neuronavigational workstations for surgical guidance. The procedure can be used with any MR postprocessed dataset, and it can be extended to other imaging modalities.  相似文献

The evolution of display technologies in PACS applications.   总被引:5,自引:0,他引:5  
Picture archiving and communications systems (PACS) systems have been around for over a decade now. The most visible components in a PACS system are the PACS workstations. Most of the clinical users of PACS only interact with the display hardware/software pieces and never truly think about the archival and communications that occur behind the scenes. This paper discusses the evolution of PACS display technology in the past 16 yr, which can roughly be divided into three phases and will also discuss future emerging trends.  相似文献

New direction in PACS education and training.   总被引:3,自引:0,他引:3  
The picture archiving and communication system (PACS) is an image information system that has become widely installed. For its successful implementation, training has been found indispensable. A review of PACS training thus far shows major emphasis was placed on the use of display workstations. As an integrated system, the PACS is much broader than the display workstations, having many components that need connectivity and customization. With the many potentials of further development, a more comprehensive education program on PACS is called for and a PACS simulator as a standalone training and research tool is deemed necessary.  相似文献

PurposeHaving access to a library of radiological images in the university setting is important for teaching and learning in diagnostic radiography. Modern modalities such as PETCT create data volumes rather than single static 2D images. A PACS repository of images alone does not constitute a teaching library without some text based searchable index. A review of several options for acquiring a digital teaching library (DTL) of such indexed DICOM data is presented.DiscussionThe data protection principles, current guidance and potential methods for migrating and cleansing large quantities of DICOM data from a clinical PACS prior to transfer to a university setting is discussed. The chosen method is described and the important enabling technology identified. Various methods of index construction are outlined and a method of migrating and cleansing HL7 data from a clinical RIS described.ResultsThree terabytes of de-normalised DICOM image files were cleansed of patient, staff and geographic identifiers, within the header tags and pixel data. These files were then migrated to an educational PACS hosted at a university. A searchable index database was created based on 90,200 reports and associated data, and 886,263 DICOM headers to enable meaningful results to be found from the 51,304 unique patient specific cases.ConclusionA large DTL in the university setting using PACS technology is becoming a valuable resource for teaching, learning and assessment.  相似文献

A PACS-based interactive teaching module for radiologic sciences.   总被引:8,自引:0,他引:8  
This article describes an interactive teaching module, linked to a picture archiving and communications system (PACS) data base, for teaching radiology. The module is currently tailored to MR images but can be adapted to any other imaging technique. An algorithm has been developed that allows the use of MR images acquired with routine clinical protocols and stored in the data base to yield, in real time, images at any other arbitrary TE and TR. In the browse mode, the user can study either the effect of different scan parameters or clinical cases on synthesized or acquired images. The quiz mode has multiple-choice questions and answers, accompanied by images. In the teaching mode, the instructor has access to the clinical data base and WRITE privileges for setting up the browse or quiz mode. The module achieves considerable flexibility when linked to the PACS, with access to all archived images and the ability to subsequently synthesize MR images at arbitrary TE and TR values in real time. The module is also "dynamic" in character, in that the instructor can easily add new cases and comments to the teaching files, both to enhance its clinical aspects and to reflect advances in technology.  相似文献

Three years'' experience with an all-digital nuclear medicine department   总被引:1,自引:0,他引:1  
We describe our all-digital, filmless, department of nuclear medicine, which has been fully operational for 3 years. The approach to the design and implementation of a nuclear medicine picture archiving and communication system (PACS) is discussed, as well as enhancements found to be necessary or desirable during our 3 years of experience using the system. Studies are initially viewed on remote monitors in the reading room, and transferred from multiple vendor's computers to the PACS by floppy disc network. Scans are analyzed on networked image workstations using a variety of software imaging tools. Reports are dictated into a digital voice storage system, allowing the referring physician immediate telephone access. The dictated report is typed into a computer, electronically edited, reviewed, billed, and printed for appropriate distribution on an integrated medical information system. The final report is stored on the PACS, along with the scan image and other patient information on 1-gigabyte removable optical discs. Two networked optical disc drives allow us to have approximately 3 years of our department's studies available instantly, allowing recall of previous studies for comparison with the current scan. Emergency night and weekend studies are sent via modern over normal phone lines to the on-call physician, who has a similar image workstation at home. Digital image storage allows for easy manipulation of the data, such as gray scale manipulation and cine (movie) display. Cost analysis shows significant savings compared with a film-based department. We conclude that an all-digital nuclear medicine department is practical, cost effective, and beneficial to both patients and staff.  相似文献

PROBLEM: This report describes the problems that can occur in the representation of the radiological workplace in a digital environment. On one hand the radiologist can sometimes access good equipment in "stand-alone" surroundings (CT, laser printer, workstations,...); on the other hand, the existing insufficient communication between different components is only rarely qualified to support the radiological workflow. This unsatisfactory framework handicaps the required clinic-wide distribution of radiological information. METHODS: From the beginning we defined user groups requiring different radiological data closely associated with specific hard- and software: The radiological workstation in the department for reporting and image processing. The demonstration workstation in wards/outpatient departments for clinicians involved in treatment. Standard PCs with access to the digital medical document for clinicians involved in treatment. At all workstations the medical as well as the legal unity of digital radiological images and the corresponding report is ensured. RESULTS: Only the first two user groups have unrestricted access to the RIS database and to the PACS archive. We have decided that the RIS should be the master of the RIS/PACS-System. For an effective master/slave relationship between RIS and PACS archive and PACS workstations we suggest to mark images and/or series of images. CONCLUSION: The third user group depends on the information exported by the radiologist from PACS. After the report is written and signed by the radiologist, the digital report is transferred from the RIS to the HIS. The report is automatically attached to these images. Authorized personnel at the wards and outpatient are able to read the combination of validated report and exported radiological images as part of the digital medical record with an intranet browser on standard PCs.  相似文献

The methodology and outcome of a hands-on workshop for the evaluation of PACS (picture archiving and communication system) software for a multihospital PACS project are described. The following radiological workstations and web-browser-based image distribution software clients were evaluated as part of a multistep evaluation of PACS vendors in March 2001: Impax DS 3000 V 4.1/Impax Web1000 (Agfa-Gevaert, Mortsel, Belgium); PathSpeed V 8.0/PathSpeed Web (GE Medical Systems, Milwaukee, Wis., USA); ID Report/ID Web (Image Devices, Idstein, Germany); EasyVision DX/EasyWeb (Philips Medical Systems, Eindhoven, Netherlands); and MagicView 1000 VB33a/MagicWeb (Siemens Medical Systems, Erlangen, Germany). A set of anonymized DICOM test data was provided to enable direct image comparison. Radiologists (n=44) evaluated the radiological workstations and nonradiologists (n=53) evaluated the image distribution software clients using different questionnaires. One vendor was not able to import the provided DICOM data set. Another vendor had problems in displaying imported cross-sectional studies in the correct stack order. Three vendors (Agfa-Gevaert, GE, Philips) presented server-client solutions with web access. Two (Siemens, Image Devices) presented stand-alone solutions. The highest scores in the class of radiological workstations were achieved by ID Report from Image Devices (p<0.005). In the class of image distribution clients, the differences were statistically not significant. Questionnaire-based evaluation was shown to be useful for guaranteeing systematic assessment. The workshop was a great success in raising interest in the PACS project in a large group of future clinical users. The methodology used in the present study may be useful for other hospitals evaluating PACS.  相似文献
