Medical Imaging PACS Solutions

In medical imaging, picture archiving and communication systems (PACS) are computers or networks dedicated to the storage, retrieval, distribution and presentation of images. The medical images are stored in an independent format. The most common format for image storage is DICOM (Digital Imaging and Communications in Medicine). Phantom Data Systems provides PACS solutions that seamlessly integrates all modalities within radiology departments in a fully integrated PACS/DICOM server, router, diagnostic viewer and storage appliance designed for receiving images directly from any DICOM modality.

Integration

A full PACS system should provide a single point of access for images and their associated data (i.e. it should support multiple modalities). It should also interface with existing hospital information systems: hospital information system (HIS) and radiology information system (RIS). Interfacing between multiple systems provides a more consistent and more reliable dataset.
Less risk of entering an incorrect patient ID for a study – modalities that support DICOM worklists can retrieve identifying patient information (patient name, patient number, accession number) for upcoming cases and present that to the technologist, preventing data entry errors during acquisition. Once the acquisition is complete, the PACS can compare the embedded image data with a list of scheduled studies from RIS, and can flag a warning if the image data does not match a scheduled study.
Data saved in the PACS can be tagged with unique patient identifiers (such as a social security number or NHS number) obtained from HIS. Providing a robust method of merging datasets from multiple hospitals, even where the different centers use different ID systems internally.

Uses

PACS replaces hard-copy based means of managing medical images, such as film archives. It expands on the possibilities of such conventional systems by providing capabilities of off-site viewing and reporting (distance education, tele-diagnosis). Additionally, it enables practitioners at various physical locations to access the same information simultaneously (teleradiology). With the decreasing price of digital storage, PACS systems provide a growing cost and space advantage over film archives. PACS is offered by virtually all the major medical imaging equipment manufacturers, medical IT companies and many independent software companies. The most difficult area for PACS systems is interpreting the DICOM image format which is implemented slightly differently among different radiology equipment vendors. The ability to point the tags in the DICOM format coming from vendors equipment to usable titles in a PACS is a feature common to most vendors and software offerings.

Architecture

Typically a PACS network consists of a central server that stores a database containing the images connected to one or more clients via a LAN or a WAN which provide or utilize the images. Web-based PACS is becoming more and more common: these systems utilize the Internet as their means of communication, usually via VPN (Virtual Private Network) or SSL (Secure Sockets Layer). The software (thin or smart client) is loaded via ActiveX, Java, or .NET Framework. Definitions vary, but most claim that for a system to be truly web based, each individual image should have its own URL. Client workstations can use local peripherals for scanning image films into the system, printing image films from the system and interactive display of digital images. PACS workstations offer means of manipulating the images (crop, rotate, zoom, brightness, contrast and others). Modern radiology equipment feeds patient images directly to the PACS in digital form. For backwards compatibility, most hospital imaging departments and radiology practices employ a film digitizer. The medical images are stored in an independent format. The most common format for image storage is DICOM (Digital Imaging and Communications in Medicine).
