“…The paradigm introduced by the Dicoogle project empowers queries over a set of distributed repositories, which are logically indexed as a single agile unit. In [51], the authors described a cloud-based relay service [52] that acts as a communication bridge between different institutions, allowing the community to access, share and discover image records [51]. Dicoogle was proposed in [53] as an architecture for cloud [52]-based PACS archives that provides data privacy, integrity and availability.…”

DICOM (Digital Imaging and Communication in Medicine) is a standard for image and data transmission in medical purpose hardware and is commonly used for viewing, storing, printing and transmitting images. As a part of the way that DICOM transmits files, the PACS (Picture Archiving and Communication System) platform, Dicoogle, has become one of the most in-demand image processing and viewing platforms. However, the Dicoogle PACS architecture does not guarantee image information recovery in the case of information loss. Therefore, this paper proposes a file recovery solution in the Dicoogle architecture. The proposal consists of maximizing the encoding and decoding performance of medical images through computational parallelism. To validate the proposal, the Java programming language based on the Reed-Solomon algorithm is implemented in different performance tests. The experimental results show that the proposal is optimal in terms of image processing time for the Dicoogle PACS storage system.

The increasing adoption of medical imaging equipment in healthcare has been leading to a huge dispersion of data repositories and institutions. Although the quality of diagnostic and treatment is deeply dependent on the health information that is available for physicians, several legal and technological issues have hindered the integration of these data. One of such problems is because traditional medical imaging protocols do not perform well in inter-institutional scenarios.This paper describes a hybrid network platform for medical imaging systems that provides searching and retrieval over multiple centres. Three key components support the system: an indexing engine, a multicast framework and a cloud service. Using a peer-to-peer paradigm with security constraints, the platform gathers the information of medical imaging repositories hosted inside the institutions, allowing physicians to access data when and where they need it.

“…After analysing the services offered by Cloud providers, we decided to use a Cloud PaaS (Platform as a Service) solution and develop the service relay as a web application. The Dicoogle Relay service was developed to run in Google App Engine (GAE) [37]. This choice does not require the acquisition and setup of a virtual machine (i.e.…”

Medical imaging is increasing its importance in matters of medical diagnosis and in treatment support. Much is due to computers that have revolutionized medical imaging not only in acquisition process but also in the way it is visualized, stored, exchanged and managed. Picture Archiving and Communication Systems (PACS) is an example of how medical imaging takes advantage of computers. To solve problems of interoperability of PACS and medical imaging equipment, the Digital Imaging and Communications in Medicine (DICOM) standard was defined and widely implemented in current solutions. More recently, the need to exchange medical data between distinct institutions resulted in Integrating the Healthcare Enterprise (IHE) initiative that contains a content profile especially conceived for medical imaging exchange: Cross Enterprise Document Sharing for imaging (XDS-i). Moreover, due to application requirements, many solutions developed private networks to support their services. For instance, some applications support enhanced query and retrieve over DICOM objects metadata.This paper proposes anintegration framework to medical imaging networks that provides protocols interoperability and data federation services. It is an extensible plugin system that supports standard approaches (DICOM and XDS-I), but is also capable of supporting private protocols. The framework is being used in the Dicoogle Open Source PACS.
