The MammoGrid Project Grids Architecture
The aim of the recently EU-funded MammoGrid project is, in the light of
emerging Grid technology, to develop a European-wide database of mammograms
that will be used to develop a set of important healthcare applications and
investigate the potential of this Grid to support effective co-working between
healthcare professionals throughout the EU. The MammoGrid consortium intends to
use a Grid model to enable distributed computing that spans national borders.
This Grid infrastructure will be used for deploying novel algorithms as
software directly developed or enhanced within the project. Using the MammoGrid
clinicians will be able to harness the use of massive amounts of medical image
data to perform epidemiological studies, advanced image processing,
radiographic education and ultimately, tele-diagnosis over communities of
medical "virtual organisations". This is achieved through the use of
Grid-compliant services [1] for managing (versions of) massively distributed
files of mammograms, for handling the distributed execution of mammograms
analysis software, for the development of Grid-aware algorithms and for the
sharing of resources between multiple collaborating medical centres. All this
is delivered via a novel software and hardware information infrastructure that,
in addition guarantees the integrity and security of the medical data. The
MammoGrid implementation is based on AliEn, a Grid framework developed by the
ALICE Collaboration. AliEn provides a virtual file catalogue that allows
transparent access to distributed data-sets and provides top to bottom
implementation of a lightweight Grid applicable to cases when handling of a
large number of files is required. This paper details the architecture that
will be implemented by the MammoGrid project.Comment: Talk PSN MOAT0005 from the 2003 Computing in High Energy and Nuclear

Provision of an integrated data analysis platform for computational neuroscience experiments
© Emerald Group Publishing Limited. Purpose – The purpose of this paper is to provide an integrated analysis base to facilitate computational neuroscience experiments, following a user-led approach to provide access to the integrated neuroscience data and to enable the analyses demanded by the biomedical research community. Design/methodology/approach – The design and development of the N4U analysis base and related information services addresses the existing research and practical challenges by offering an integrated medical data analysis environment with the necessary building blocks for neuroscientists to optimally exploit neuroscience workflows, large image data sets and algorithms to conduct analyses. Findings – The provision of an integrated e-science environment of computational neuroimaging can enhance the prospects, speed and utility of the data analysis process for neurodegenerative diseases. Originality/value – The N4U analysis base enables conducting biomedical data analyses by indexing and interlinking the neuroimaging and clinical study data sets stored on the grid infrastructure, algorithms and scientific workflow definitions along with their associated provenance information
Grid Databases for Shared Image Analysis in the MammoGrid Project
The MammoGrid project aims to prove that Grid infrastructures can be used for
collaborative clinical analysis of database-resident but geographically
distributed medical images. This requires: a) the provision of a
clinician-facing front-end workstation and b) the ability to service real-world
clinician queries across a distributed and federated database. The MammoGrid
project will prove the viability of the Grid by harnessing its power to enable
radiologists from geographically dispersed hospitals to share standardized
mammograms, to compare diagnoses (with and without computer aided detection of
tumours) and to perform sophisticated epidemiological studies across national
boundaries. This paper outlines the approach taken in MammoGrid to seamlessly
connect radiologist workstations across a Grid using an "information
infrastructure" and a DICOM-compliant object model residing in multiple
distributed data stores in Italy and the UKComment: 10 pages, 5 figure
Grid simulation services for the medical community
The first part of this paper presents a selection of medical simulation applications, including image reconstruction, near real-time registration for neuro-surgery, enhanced dose distribution calculation for radio-therapy, inhaled drug delivery prediction, plastic surgery planning and cardio-vascular system simulation. The latter two topics are discussed in some detail. In the second part, we show how such services can be made available to the clinical practitioner using Grid technology. We discuss the developments and experience made during the EU project GEMSS, which provides reliable, efficient, secure and lawful medical Grid services
End-to-End QoS Support for a Medical Grid Service Infrastructure
Quality of Service support is an important prerequisite for the adoption of Grid technologies for medical applications. The GEMSS Grid infrastructure addressed this issue by offering end-to-end QoS in the form of explicit timeliness guarantees for compute-intensive medical simulation services. Within GEMSS, parallel applications installed on clusters or other HPC hardware may be exposed as QoS-aware Grid services for which clients may dynamically negotiate QoS constraints with respect to response time and price using Service Level Agreements. The GEMSS infrastructure and middleware is based on standard Web services technology and relies on a reservation based approach to QoS coupled with application specific performance models. In this paper we present an overview of the GEMSS infrastructure, describe the available QoS and security mechanisms, and demonstrate the effectiveness of our methods with a Grid-enabled medical imaging service
