Components of an integrative system are not only required to offer rich functionality for fulfilling their designated purpose (e.g. According to improve functionality and optimize the workflow, the requirements to interfaces of the software components increase with each of the levels.
Four increasing levels of integration for connecting a DICOM viewer, a PACS and an EDCS have been discussed in previous work. Appropriate DICOM viewers are not yet integrated. Up to now, visualization of DICOM objects in ecrfs is impossible. Neither a structured way to integrate DICOM data into EDCS, nor interfaces for communication with PACS exist. This improves data quality and simplifies access in multi-centered trials. ECRFs allow data evaluation by automatic range checks and can be accessed via web. Here, patient s data is captured using electronic data capture systems (EDCS), which provide electronic case report forms (ecrfs) instead of the traditional paper-based CRFs. Image-based surrogate endpoints offer qualitative and quantitative disease findings improving eligibility, efficacy, and security evaluation in studies.
CONQUEST AND WEASIS FREE
Almost 350 free software projects are currently listed in the database of the I Do Imaging web site ( Furthermore, medical imaging is looming large today in clinical trials. Due to DICOM s popularity, a broad range of commercial as well as free or open source software tools have been developed up to today. Since its release in 1993, DICOM is applied to capture, exchange and store image data via DICOM workstations and picture archiving and communication systems (PACS). INTRODUCTION Nowadays, the digital imaging and communications in medicine (DICOM) protocol of the National Electrical Manufacturers Association (NEMA) and the American College of Radiology (ACR) has been established as the leading standard for image data management in medical applications. Keywords: DICOM, EDCS, ecrf, Data Capture, Integration, Interfaces, Display 1. Covering most use cases, an EDCS and PACS interconnection with Weasis is suggested.
Concerning workflow optimization in multi-centered clinical trials, we suggest the open source viewer Weasis. Focusing on open source solutions, the viewers ImageJ and MicroView are superior for 3D visualization, whereas GingkoCADx is advantageous for hospital integration. Optimal viewers are suggested for applications in clinical trials for 3D imaging, hospital communication, and workflow. Concerning general, integration, and viewing requirements the survey involves the criteria (i) license, (ii) support, (iii) platform, (iv) interfaces, (v) twodimensional (2D) and (vi) three-dimensional (3D) image viewing functionality. Hence, in this paper, a comprehensive evaluation of 27 DICOM viewer software projects is performed, investigating viewing functionality as well as interfaces for integration. Four increasing levels for integration of DICOM components into EDCS are conceivable, raising functionality but also demands on interfaces with each level. Due to missing integration, even just the visualization of patient s image data in electronic case report forms (ecrfs) is impossible. However, different from patient s care in hospital, DICOM has not yet arrived in electronic data capture systems (EDCS) for clinical trials. A broad range of commercial, free, and open source software tools supporting a variety of DICOM functionality exists.
