Step-By-Step PACS Implementation Guide

Posted in PACScribe

Legacy imaging systems lag the rest of the workflow infrastructure. Integrations with EHRs are partial, reports take too long to circulate, all the while the cost of maintaining dated equipment keeps rising. A proper PACS system like PACScribe by Folio3 Digital Health addresses these issues directly. It connects all the modalities, information systems, and clinicians under one interoperable framework. This step-by-step guide details how to plan, deploy, and sustain a PACS system, reducing overhead while improving clinical access and workflow reliability.

11 Step Process of PACS Implementation

1. Defining Purpose and Scope

• Organizations intending to get a PACS system must determine what they want the system to achieve. Whether it is to have faster reporting, get centralized access, or enterprise imaging expansion. Without a clear purpose, even the best system can underperform.
• Defining scope helps control scale. A facility focusing only on radiology will plan differently than one connecting cardiology, oncology, and orthopedics.
• The scope is incomplete without outcomes. Set turnaround targets or image retrieval times so everyone has a common vision and goal.
• Stakeholders from clinical, IT, and management backgrounds work together to make sure PACS goals align with patient care and hospital efficiency.
• This early definition turns a vague modernization idea into a mission-driven initiative with measurable objectives.
  

2. Build the Governance and Planning Structure

• Implementation begins with organizations forming a multidisciplinary steering committee that includes radiology leaders, IT staff, biomedical engineers, finance, and administrators.
• Governance ensures decisions balance clinical needs, technical realities, and cost considerations instead of being driven by one group alone.
• Keep short milestones to measure progress. Procurement, infrastructure readiness, training, and go-live, all these give structure to a complex project.
• Responsibilities are clearly assigned, so each team owns its part: IT secures the network, radiology designs workflows, and management oversees budget and compliance.
• Strong governance transforms PACS from a departmental project into a unified institutional effort.

3. Assess and Prepare the Technical Infrastructure

• Network assessments identify bandwidth gaps, switch limitations, and areas needing fiber or gigabit upgrades.
• Imaging devices (CT, MRI, X-ray) are reviewed for DICOM compliance, ensuring seamless data exchange once connected.
• Tiered storage is designed to balance performance and cost. High-speed disks for recent studies and archival systems for long-term retention.
• Redundant servers, firewalls, and UPS systems are configured to maintain 24/7 availability even during hardware failures.
• A solid technical foundation guarantees that PACS remains fast, reliable, and secure, regardless of imaging volume.

4. Map Current Imaging Workflows

• Mapping each imaging workflow reveals how orders, images, and reports currently move across departments.
• Inefficiencies like duplicate entry, manual scheduling, or lost CDs are documented and targeted for improvement.
• The mapping exercise informs PACS configuration. Enabling Modality Worklists to automatically populate patient data at scanners.
• Staff engagement during this step builds trust and ownership, showing that the system is being tailored to their daily work, not imposed from above.
• Workflow mapping ensures that technology integrates seamlessly with people, not the other way around.

5. Select the Vendor and Finalize the Solution

• Selecting a PACS vendor is a critical technical and strategic decision. Hospitals assess products for standards compliance (DICOM, HL7, FHIR), scalability, and proven performance in similar environments.
• Demonstrations and reference checks help verify how the system performs in real clinical settings.
• Evaluation criteria extend beyond price, uptime, service responsiveness, and interoperability weigh equally.
• Contracts clearly define service levels, warranties, and support obligations to protect long-term reliability.
  

6. Install and Configure the System

• Once infrastructure and vendor contracts are ready, physical and virtual servers are deployed in secure data centers.
• PACS applications are installed and configured with routing rules, storage policies, and user access permissions.
• Diagnostic workstations are equipped with high-resolution, calibrated medical monitors to maintain image fidelity.
• Backup and disaster recovery mechanisms are implemented to ensure no data is lost even in the event of hardware failure.
• Test studies are run to validate that images transmit, store, and display correctly before going live.

7. Integrate PACS with HIS, RIS, and Other Systems

• Using HL7 and DICOM standards, patient demographics, orders, and reports flow automatically between systems.
• This eliminates redundant data entry, reduces errors, and ensures every system shows the same patient information.
• Interface engines or brokers handle message translation between HIS, RIS, and PACS to maintain smooth communication.
• End-to-end tests simulate the complete patient journey, from registration to image and report access to confirm data accuracy.
• Integration makes PACS a unified clinical tool instead of a standalone repository.

8. Connect and Test Imaging Modalities

• Each imaging device is configured to communicate with PACS through DICOM protocols, with unique AE Titles and IP addresses.
• Worklists are enabled so modalities can retrieve scheduled exams directly, saving time and preventing patient ID errors.
• Sample studies are acquired and validated for image completeness, tagging, and correct routing.
• Any transmission errors or mismatches are resolved before clinical use.
• Once connected, PACS becomes a live, intelligent network that automatically captures, indexes, and stores imaging data.

9. Train Users and Prepare for Change

• Effective training builds confidence, not just competence. Each user group that includes radiologists, technologists, and clinicians, receive hands-on instruction tailored to their role.
• Simulated exercises with test patients let users practice workflows without clinical pressure.
• The rationale for change is communicated clearly: less manual work, faster access, and fewer delays in patient care.
• “Super users” are trained to act as in-house experts who can guide colleagues after go-live.

10. Go-Live and Stabilize Operations

• Launching PACS in phases allows teams to learn and refine processes in a safe environment. Radiology often goes first before expanding to other specialties.
• The old and new systems may run in parallel initially to catch potential issues early.
• IT and vendor teams remain onsite to troubleshoot, ensuring clinicians face minimal disruptions.
• System performance is continuously monitored for speed, stability, and reliability.
• Once it stabilizes, PACS takes over the legacy system.

11. Monitor and Maintain

• After launch, PACS becomes part of daily hospital operations and needs constant care.
• Routine tasks like backups, patch updates, and log reviews keep the system secure and efficient.
• Performance dashboards track uptime, response time, and report turnaround, ensuring quality never drifts.
• User feedback drives incremental improvements such as refined search tools or streamlined routing.
• Continuous maintenance ensures that PACS stays current with growing workloads and evolving standards.
