PACS (Picture Archive Communication System) is becoming a standard tool in radiology for storing and viewing digital medical images. It provides benefits like higher quality images, instant access to patient films from any location, and integration with digital medical records. PACS acquires images directly from medical equipment, stores them in a database, and allows viewing through workstations. It replaces physical film with a digital system for more efficient sharing of images between radiology staff and physicians.

1. PACS in Modern Healthcare PACS is quickly becoming a standard tool in the field of radiologic diagnostic imaging. Benefits of PACS: Higher quality images. Patient film instantly available. Film can not be lost. No more bad exposures. Compliant with digital medical record initiatives.

2. HIS, RIS, & PACS Various Information Systems work together to assist in providing modern health care: HIS stands for Health Information System. A database that controls patient admissions, discharges, transfers, and orders. RIS stands for Radiology Information System. A specialized database that is specific to diagnostic imaging procedures that are ordered for patients. PACS stands for Picture Archive Communication System. A high end database that stores diagnostic images and their associated procedure results.

3. Image Acquisition PACS acquires images directly from the diagnostic equipment where the exams are performed on the patient. Orders are input to the HIS. HIS transfer order request automatically to both RIS and PACS. Employee will perform exam on a Modality. Modalities are X-Ray machines, Cat Scan, MRI, Ultrasound. Employee will send images from exam to PACS. Physician will interpret images through a PACS viewing workstation.

4. Network Infrastructure PACS operates best on a Gigabit network connection. It is ideal to use: Category 6 Ethernet cabling. Gigabit network switches . Private VLAN management.

7. PACS Architecture In the simplest concept, PACS is an online, digital file room but there is actually much more to it: High end database servers sort incoming orders and link information to patient data. Image acquisition servers communicate directly with the imaging modalities. Storage servers control short term and long term access to patient records. Interface servers communicate with other Information Systems. Web servers allow films and records to be viewed anywhere in the world through the internet. Customized workstations allow Radiology staff technologists and radiologists to view, manipulate, and interpret the diagnostic images.

8. Workflow PACS is a tool that makes it easier for the healthcare staff to do their job. Efficiency is gained by not physically transporting film to various destinations.

9. Teleradiology Accessibility is an important feature in today’s workplace and healthcare is no exception. With the investment of a Virtual Private Network appliance, facilities are able to provide connectivity to services during off-business hours. In healthcare, time is not money, it’s life. Vital seconds waiting for a radiologist to drive to the site of care is eliminated by providing access over a secured connection, allowing diagnostic interpretations to occur at home or on the go.

10. Web Distribution Not only are patients, in reality, customers of the healthcare industry but so are the referring physicians who send in the orders for diagnostic testing. It is essential to provide the ordering doctors with real time access to the images and radiologist findings. With the Web server component of PACS, any computer with internet access becomes a powerful tool to aid in care for the sick. Many PACS vendors are also marketing their product to smart phone users, providing additional access.

11. Conclusion In its simplest concept, PACS is an online digital file room. PACS is a significant investment for the technology implementation. Efficiency is gained by eliminating physical film and faster availability to all parties involved. PACS provides real time access in the form of a Web presence. PACS is becoming more prevalent in health care environment as there is an initiative to move medical records into a digital format.
