Web-Based PACS–Why You Should Upgrade
PACS RIS are two related software and hardware systems that are used on computers. PACS means picture archiving and communications system, and RIS stands for radiology information system. The PACS RIS system may be a mini-pacs system format or it could be a web-based pacs. A pacs server and software system are known as a mini-pacs when they are used to read only one type of image modality, such as mammograms, rather than digital images taken from multiple modalities. PACS on the web uses secure transmission provided by a secure socket layer or a virtual private network to allow transmission of digital medical images and other data over the Internet. RIS takes radiology digital images and data and allows that information to be stored, distributed, and archived.
One reason why medical facilities, especially small and mid-sized ones, are switching to PACS on the web is that in recent years the price has come down dramatically. Although PACS has been around for a while, it was typically only available to the largest hospitals and facilities because the cost of the software and equipment were out of reach for smaller facilities. Because all computer technology has come down in price over the years, this has had an beneficial impact on the cost of purchasing a pacs server and software.
Another reason that medical offices are upgrading to pacs on the web is the speed it offers. It was not that long ago that images were taken on film, which then took time to be developed. After this, if a consultation was necessary, the films would have to be sent by postal mail to the consulting physician. This was a very time consuming process, but thankfully it can be speeded up considerably with the use of the Internet. Now digital medical images can be translated by the pacs server quickly using the DICOM format, and those images can be sent in seconds rather than days to physicians located nearly anywhere in the world for consultations. This has also enabled better teaching experiences for medical students, who can now be exposed to a vast array of digital images via the Internet as well.
In order to save money and time, it makes sense to upgrade to a web-based PACS RIS or mini-pacs system.

Functions Of A PACS RIS System
To begin, PACS RIS are two separate but related features. PACS stands for Picture Archiving and Communication System, while RIS means Radiology Information System. PACS has to do with digital medical imaging, and it is a software and hardware system that allows medical facilities to store, view, retrieve, send and receive digital medical images from a computer. RIS is a software database that enables radiology departments to archive and distribute both digital medical images as well as other types of data such as patient scheduling, tracking and reporting. When used together, they greatly improve the workflow for any radiology department in a small or large medical facility.
A pacs server allows medical personnel to obtain images from various modalities, such as mammographies, MRIs and CTs, and then take those digital images and view them on a workstation, store them in archives and transmit them via a secure network. PACS RIS also come as mini-pacs and web-based pacs. Mini-pacs are an extremely focused type of pacs system that allows you to use images taken from one type of modality, rather than multiple modalities as can be done on a full pacs system, and then manipulate them on a workstation. A web-based pacs is a system that allows you to send and receive digital medical images and other data over the Internet. They use secure transmissions over virtual private networks or secure socket layer. The web-based aspect of the pacs has changed how medical offices function, because now it is a simple matter to remotely work nearly anywhere in the world due to the use of the World Wide Web, and this also allows for improved consultations with physicians located down the hall or across the world from you.
A RIS PACS system helps keep a radiology department organized in terms of patient care. With this type of system, departments can track the registration and scheduling of their patients. It is easy to create test requests and results entries, reports and printouts automatically. The system can handle emailing clinical reports, and can be used to book patient appointments, to maintain your office workflow, and even to create customized reports. Many systems also take care of billing as well.
For the speed and ease of use brought about by this new technology, many medical offices are switching over to a pacs server.

Integrating a Mini-PACS Workstation
This process is already going on at large for-profit medical centers and major university hospitals; however, for smaller health care facilities and non-profits, often the decision is more complex. This is particularly true of specialty clinics and radiology facilities that focus on one type of medical issue and a single type of modality. Is it better to go with a mini-PACS that serves present needs and deal with the problem of integration when it comes, or should the facility make the costly investment of a full PACS-RIS?
Fortunately, drops in the cost of technology have made such components as the PACS server more affordable for smaller and less well-funded clinics and health care facilities. The web-based PACS makes integration of older specialized systems much less expensive than even a few years ago; prices on a fully-functional PACS-RIS that is capable of reading, processing and storing a wide range of medical images in various modalities start at around $5000.
Granted, a lower-end PACS-RIS will have some limitations; however, it may be the best choice for smaller clinics as it will allow the facility continue to provide much-needed patient services while upgrading its equipment in stages as finances allow.
Keep in mind that due to several factors, there is currently a shortage of qualified radiologists. With a web-based PACS possible to consult with a radiologist almost anywhere in the country. It is possible to add a radiology component to an existing mini-PACS for a reasonable cost; in fact, many such specialized systems have elements radiology imaging built-in.
If yours in a clinic that deals with a single modality, just be aware that because of economics, demographics and a greater need for efficiency, the trend is toward full PACS integration; stand-alone applications will become increasingly rare. Advance planning and some research into the various PACS options available will be of great help for smaller clinics, non-profit facilities and even private practices when it comes to preparation for full PACS integration and the moving toward the establishment of a full-service facility.
