CyclopsDistMedDB - a transparent gateway for distributed medical data access in DICOM format

Abstract

The image diagnosis area is the most propense medical field to Telemedicine, because it does not obligate a direct contact of the patient with the responsible radiologist during the building of the report. The persistent lack of specialists on places distant from urban centers makes the Telemedicine an important tool for improvement of healthcare services. In this work we present a framework, called CyclopsDistMedDB, for the integration of distributed DICOM medical record databases over wide areas. The present system has a central module that is responsible for receiving the clients requests about patient data (images, waveforms), performing the querying and retrieval of images, patient records etc. from the specific DICOM databases containing the data requested and delivering them to the clients. The data communication protocols adopted are DICOM, for retrieval of objects directly from DICOM data servers and CORBA (Common Object Request Broker) for the delivery of DICOM data to client applications.

Armazenamento distribuído de imagens médicas DICOM no formato de dados HDF5

“…Ele foi desenvolvido para funcionar em ambientes PACS, dentro de hospitais ou clínicas radiológicas. Entretanto, devidoàs necessidades de expansão, ele foi remodelado para trabalhar em redes de longa distância, onde foram incluídos aspectos de tolerância a falhas, tratamento de erros, entre outros aspectos [16].…”

Armazenamento de Imagens Médicas DICOM em Sistemas de Arquivos Distribuídos

“…Ele foi desenvolvido para funcionar em ambientes PACS, dentro de hospitais ou clínicas radiológicas. Entretanto, devido às necessidades de expansão, ele foi remodelado para trabalhar em redes de longa distância, onde foram incluídos aspectos de tolerância a falhas, tratamento de erros, entre outros aspectos [16]. Um dos principais objetivos deste servidor é armazenar e fornecer arquivos DICOM indexados em um repositório de dados gerenciado por SGBDs relacionais, tais como: Post-greSQL, MySQL, Oracle, etc.…”

Integrating CBR into the health care organization

“…We also have developed solutions for very special problems, amongst others a system to detect breast cancer in contrast enhanced MR sequences early [5], a system to reconstruct and measure aortic aneurysms for the design of personalized endoluminal prostheses [11], and an application to detect and quantify Neurocysticercosis in CT scans of epileptic patients [12]. All these systems are used in the daily routine of our partner hospitals and clinics in Germany and Brazil, because they are connected with CyclopsDistMedDB, our transparent gateway for distributed data access in DICOM 1 format [13]. CyclopsDistMedDB is Client/Server based and is installed on every computer within the hospitals, so during every process step (registration of the patient, anamnesis, diagnosis, etc.)…”
