Vista imaging



  VistA Imaging is an FDA-approved Image Management system used in the Department of Veterans Affairs healthcare facilities nationwide. It is one of the most widely used image management systems in routine healthcare use, and is used to manage many different varieties of images associated with a patient's medical record.

Hardware requirements

The VistA Imaging System uses hardware components to provide short- and long-term storage. It takes advantage of network servers for storage. It uses a DICOM gateway system to communicate with commercial Picture Archiving and Communication Systems (PACS) and modalities such as CT, MR, and Computed Radiography (x-ray) devices for image capture. It utilizes a background processor for moving the images to the proper storage device and for managing storage space.

Types of data managed

The system not only manages radiologic images, but also is able to capture and manage EKGs, pathology images, gastroenterology (endoscopic) images, laparoscopic images, scanned paperwork, or essentially any type of health care image.

Integration with Electronic Health Record systems

VistA Imaging is currently integrated into the VistA EMR (electronic medical record) system used nationwide in Department of Veterans Affairs hospitals. This integration is able to provide increased efficiency of retrieval of images.[1] It has also been used as a separate software package and can be used with EHRs other than VistA.

VistA Imaging now connects to a nationwide backbone that allows clinicians to access the 350 million images stored in the VA system via Remote Image View software.[2]

The VA has developed interfaces for more than 250 medical devices in VistA Imaging, the images from which can be accessed through the desktop VistA Imaging Viewer. The Department of Defense will use the VistA Imaging Viewer to enhance its own EHR.[2]

Availability

The software for VistA Imaging has been made available through the Freedom of Information Act so that it is in the public domain. Due to its designation as a medical device, it can not be designated as open source and therefore can not be altered without FDA approval. However, it can be used in healthcare facilities that are outside the Department of Veterans Affairs. It is available through the Department of Veterans Affairs software request office for a nominal fee (around $15).
