Paper Abstract

The Digital Imaging and Communications in Medicine (DICOM) standard was developed by the National Electrical Manufacturers Association (NEMA) and the American College of Radiology (ACR) for medical image archiving and retrieval. An extension to this implemented a standard named DICOM-RT for use in Radiation Oncology. There are currently seven radiotherapy-specific DICOM objects which include: RT Structure Set, RT Plan, RT Dose, RT Image, RT Beams Treatment Record, RT Brachy Treatment Record, and RT Treatment Summary Record. The type of data associated with DICOM-RT includes (1) Radiation treatment planning datasets (CT, MRI, PET) with radiation treatment plans showing beam arrangements, isodose distributions, and dose volume histograms of targets/normal tissues and (2) Image-guided radiation modalities such as Siemens MVision mega-voltage cone beam CT (MV-CBCT). With the advent of such advancing technologies, there has been an exponential increase in image data collected for each patient, and the need for reliable and accessible image storage has become critical. A potential solution is a Radiation Oncology specific picture archiving and communication systems (PACS) that would allow data storage from multiple vendor devices and support the storage and retrieval needs not only of a single site but of a large, multi-facility network of radiation oncology clinics. This PACS system must be reliable, expandable, and cost-effective to operate while protecting sensitive patient image information in a Health Insurance Portability and Accountability Act (HIPAA) compliant environment. This paper emphasizes the expanding DICOM-RT storage requirements across our network of 8 radiation oncology clinics and the initiatives we undertook to address the increased volume of data by using the ImageGrid (CANDELiS Inc, Irvine CA) server and the IGViewer license (CANDELiS Inc, Irvine CA) to create a DICOM-RT compatible PACS system.
