The mantisGRID is a GRID platform, based on open source grid infrastructure that provides the necessary services to access and exchange medical images and associated information following digital imaging and communications in medicine (DICOM) and health level 7 standards. The paper focuses first on the data abstraction architecture, which is achieved via Open Grid Services Architecture Data Access and Integration (OGSA-DAI) services and supported by the Globus Toolkit. The grid currently uses a 30-Mb bandwidth of the Colombian High Technology Academic Network, RENATA, connected to Internet 2. It also includes a discussion on the relational database created to handle the DICOM objects that were represented using Extensible Markup Language Schema documents, as well as other features implemented such as data security, user authentication, and patient confidentiality. Grid performance was tested using the three current operative nodes and the results demonstrated comparable query times between the mantisGRID (OGSA-DAI) and Distributed mySQL databases, especially for a large number of records.enghttps://v2.sherpa.ac.uk/id/publication/issn/0897-1889ColombiaColombiansData abstractionData accessDigital imaging and communications in medicinesGlobus ToolkitGrid infrastructuresGrid performanceGrid platformGrid servicesHealth level 7Health level 7 (HL7)HealthgridHigh technologyHigh-performance computingInternet2Latin AmericaMedical imagesMySQL databaseOGSA-DAIOpen grid services architectureOpen sourcesPatient confidentialityQuery timeRelational DatabaseUser authenticationAuthenticationComputer software selection and evaluationMedical applicationsMedical imagingMedicineNetwork architectureOpen systemsXMLGrid computingarticleColombiadata basefactual databasehospital information systemhumanmedical informaticsmethodologySouth and Central AmericaColombiaDatabase Management SystemsDatabasesFactualHumansLatin AmericaMedical InformaticsRadiology Information Systemsinfo:eu-repo/semantics/article2021-04-12Garcia Ruiz MGarcía, A.Ruiz Ibañez CGutierrez Mazo JMRamirez Giraldo JCPelaez Echavarria AValencia Diaz EPelaez Restrepo GMontoya Munera ENGarcia Loaiza BGomez Gonzalez S10.1007/s10278-009-9265-x
