Purpose

This paper aims to present a novel DSpace-based medical image repository system planned explicitly for storing and retrieving clinical images using digital imaging and communication in medicine (DICOM) metadata standards. DSpace institutional repository software is widely used in an academic environment for accessing and mainly storing text-related files. DICOM images are particular types of images embedded with much system-generated metadata and organised using DICOM metadata standards.

Design/methodology/approach

The present paper talks about institutional repository software (DSpace) in archiving DICOM images. In the current study, the authors have tried to integrate the DICOM metadata standard with DSpace, which was compatible with Dublin Core (DC) and open archives initiative – protocol for metadata harvesting (OAI-PMH). After combining the DICOM standard with DSpace and the repository tested with a sample of 5,000 images, the retrieval results using various DICOM tags was very satisfactory. This study paves for the use of open source software (OSS) in storing and retrieving medical images.

Findings

The author has provided the DSpace software to recognised DICOM (.dcm) files in the first stage. In the second stage, a patch was developed to identify the DICOM metadata standard in Dspace, which has inbuilt DC metadata standards. Finally, in the third stage, retrieval efficiency was tested with a 5,000 .dcm image using the DICOM tag and the results were very fruitful.

Research limitations/implications

A major limitation of this study was the size of the data (5,000 DICOM images) with which the authors have tested the system. The system scalability has to be tested on various fronts like on cloud and local servers with different configurations, for which a separate study has to be done.

Practical implications

Once this system is in place, DICOM users can stock, retrieve and access the image from the Web platform. Furthermore, this proposed repository will be the warehouse of various DICOM images with reasonable storage costs.

Originality/value

In addition to exploring the opportunities of free open source software (FOSS) implementation in medical science, this study includes issues related to the performance of an open-source repository for retrieving and preserving medical images. It created and developed Open Source DICOM Medical Image Library with DICOM metadata standard with the help of DSpace. Thus, the study will generate value for library professionals and medical professionals and FOSS vendors to understand the medical market in the context of FOSS.

使用 DSpace 开发 DICOM 标准模式

目的

本文旨在提出一种新的基于 DSpace 的医学图像存储系统，该系统明确计划用于使用医学数字成像和通信 (DICOM) 元数据标准存储和检索临床图像。DSpace 机构存储库软件广泛用于学术环境中，用于访问和主要存储与文本相关的文件。DICOM 图像是嵌入了许多系统生成的元数据并使用 DICOM 元数据标准组织的特定类型的图像。

设计/方法/方法

本文讨论了归档 DICOM 图像中的机构存储软件 (DSpace)。在当前的研究中，作者试图将 DICOM 元数据标准与 DSpace 集成，该标准与都柏林核心 (DC) 和开放档案倡议 - 元数据收集协议 (OAI-PMH) 兼容。将 DICOM 标准与 DSpace 相结合，并以 5000 张图像的样本测试存储库后，使用各种 DICOM 标签的检索结果非常令人满意。这项研究为使用开源软件 (OSS) 存储和检索医学图像铺平了道路。

发现

作者在第一阶段提供了DSpace软件来识别DICOM（.dcm）文件。在第二阶段，开发了一个补丁来识别 Dspace 中的 DICOM 元数据标准，该标准具有内置的 DC 元数据标准。最后，在第三阶段，使用 DICOM 标签对 5000 .dcm 的图像进行了检索效率测试，结果非常富有成效。

研究限制/影响

这项研究的一个主要限制是作者用来测试系统的数据量（5,000 张 DICOM 图像）。系统可扩展性必须在各个方面进行测试，例如在具有不同配置的云和本地服务器上，为此必须进行单独的研究。

实际影响

一旦该系统到位，DICOM 用户就可以从 Web 平台存储、检索和访问图像。此外，这个提议的存储库将是各种 DICOM 图像的仓库，具有合理的存储成本。

原创性/价值

除了探索在医学科学中实施免费开源软件 (FOSS) 的机会外，本研究还包括与用于检索和保存医学图像的开源存储库的性能相关的问题。它在 DSpace 的帮助下创建和开发了具有 DICOM 元数据标准的开源 DICOM 医学图像库。因此，该研究将为图书馆专业人员和医疗专业人员以及 FOSS 供应商在 FOSS 的背景下了解医疗市场创造价值。
