"Since QARC interacts with investigators in six continents, the data arrive in many electronic formats, both with and without proprietary headers, often creating unique issues in opening and archiving data," said Nicole Laprise, project manager for Dicommunicator software.Īs QARC geographically expands the scope of its image acquisition, the pool becomes even more diverse. He subsequently donated it for use in the clinical trials process. White of Primary Children's Hospital at the University of Utah. Dicommunicator was originally developed by Dr. QARC was forced to devise a sophisticated DICOM image transfer system called Dicommunicator to provide a user-friendly means of managing the imaging data it receives from widely disbursed researchers (J Digit Imaging 2007 Oct. While each site creates and stores imaging studies in DICOM format, DICOM image attributes and values are not uniform among the various vendors. The Quality Assurance Review Center, a research program within the University of Massachusetts Medical School that supports several National Cancer Institute-sponsored trials, acquires digital imaging data from institutions from around the world. Supported by NIH U24 Grant CA81647 and NCI-H Grant 5U10CA02951.One of the major challenges in providing management of imaging studies for multi-institutional clinical trials is accommodating image files created by a variety of PACS. The effort required, however, was significant and tools must be tailored to each individual QA center's computer infrastructure/QA process.
This project demonstrates that ATC Method 1, successfully used in support of RTOG trials for many years at ITC, can be implemented at other QA centers.
Conclusion: Widespread use of new treatment modalities such as IMRT, makes use of 3D datasets essential for complete evaluation of ROI delineation and assessment of agreement of dosimetric parameters with protocol requirements. The system is in use for six COG, CALGB, ACOSOG, and ECOG protocols 28 cases from 15 institutions have been received and reviewed (3/1/06).
Qarc system software#
QARC software was adapted to support RRT invocation directly from the QARC database user interface. RRT enhancements include selectable DVHs, distance measurement tool, and image grayscale presets. ITC software was adapted to better support the QARC QA process. (Proprietary software components were used by special arrangement with CMS, Inc.) Results: Software installation and maintenance were performed remotely at QARC by ITC personnel, with weekly teleconferences to coordinate the development effort. The system includes an FTP server for receiving TPD (in DICOM or RTOG data exchange format) from protocol participants, utilities for importing TPD into a local file format, and the web-based Remote Review Tool (RRT) for QA of ROIs, isodoses, DVHs, and dose statistics. Method and Materials: A system of software (“ATC Method 1”) developed at the Image-guided Therapy QA Center (ITC) as part of the Advanced Technology QA Consortium (ATC) to receive, process, and review volumetric TPD for clinical trials was ported to a Linux workstation at QARC.

Purpose: To develop the capability at the Quality Assurance Review Center (QARC) to receive and review digital radiation therapy treatment planning data (TPD) for clinical trial case review.
