What is PACS Imaging?

You might’ve heard of the PACS Imaging system but are unsure what it is. PACS stands for picture archiving and communications system. PACS diagnostic imaging is imaging software that provides an efficient system to securely share and transport private patient medical imaging information, unlike traditional manual filing, retrieving, or physically transporting film jackets.

With PACS diagnostic imaging, medical professionals store and digitally transmit images and clinical reports for immediate use at their discretion. PACS imaging software allows medical documents and photos to be housed locally or offsite on secure servers and accessed using PACS software, workstations, or mobile devices.

According to a report by the Radiology Society, enterprise imaging PACS have several benefits: economical storage, quick retrieval of images, access to images acquired with multiple modalities, and the ability to access various sites at once. Technologies like PACS are becoming popular in the healthcare industry due to their compatibility with systems like HL7 Healthcare.

The Key Components of a PACS System

Practical digital imaging and PACS system consists of four essential components, which include: 

• Imaging modalities
• Secure network to the database for data sharing
• Workstation for radiologists and doctors
• Archives for storage

A PACS system, or Picture Archiving and Communication System, is the backbone of digital medical imaging PACS. It allows efficient medical image capture, storage, retrieval, and sharing. Here’s a breakdown of the four essential components that make a PACS system function:

Imaging Modalities:

This refers to the various machines that capture medical images. Examples include X-rays, CT scanners, MRIs, and ultrasound machines. These devices generate digital images that are then fed into the PACS system.

• Image Acquisition: These machines capture internal body structures using X-rays, CT scans (computed tomography), MRI (magnetic resonance imaging), and ultrasound.
• DICOM Standard: PACS utilizes the DICOM (Digital Imaging and Communications in Medicine) standard to ensure compatibility. DICOM formats the images with patient information, study details, and specific image data for seamless integration into the PACS system.
• Automation Capabilities: Modern modalities can automate certain functions, like image stitching for panoramic X-rays or reconstruction for 3D models in CT scans, reducing processing time.

Secure Network:

A secure network is crucial for transmitting medical images between modalities, workstations, and archives. This network ensures the privacy and confidentiality of patient data by using encryption and access controls.

• Encryption: The network utilizes encryption protocols to scramble data during transmission, safeguarding patient privacy and preventing unauthorized access.
• Access Control: Robust access control mechanisms restrict access to authorized personnel based on their roles and permissions within the healthcare facility.
• High Bandwidth: A high-bandwidth network ensures smooth and efficient transmission of large medical image files, minimizing image retrieval and interpretation delays.

Workstation:

Workstations are specialized computers that radiologists and other authorized healthcare professionals use to view, analyze, and interpret medical images. These workstations offer features for manipulating images, adding annotations, and generating reports.

• Image Manipulation Tools: Workstations offer features for zooming, panning, windowing, and leveling images to optimize visualization for diagnosis.
• Annotation Tools: Radiologists can annotate images with findings, measurements, and labels for clear communication and documentation.
• Reporting Tools: Workstations may integrate with reporting software, allowing radiologists to generate detailed reports with interpretations and recommendations.
• Advanced Visualization Tools: Some workstations offer advanced visualization tools like 3D reconstruction capabilities, aiding in complex diagnoses.

Archive:

The archive is the heart of the PACS system, responsible for storing and managing the vast amount of medical images generated. It provides secure, reliable, and long-term storage for patient data, ensuring accessibility for future reference or consultations.

• Long-Term Storage: The archive provides secure and reliable storage for vast medical images, ensuring accessibility for future reference or consultations, even years after the initial exam.
• Data Compression: PACS employs data compression techniques to optimize storage space without compromising image quality.
• Disaster Recovery: Robust PACS systems have built-in disaster recovery mechanisms to protect against data loss due to hardware failures or natural disasters.
• Retention Policies: Archives may adhere to specific retention policies mandated by regulations or internal hospital guidelines, determining how long images are stored before being securely purged.

The Power of PACS: Benefits for Healthcare Professionals

Digital technologies such as PACS are gaining popularity among healthcare providers and patients. Due to its timeliness, as this is one of the significant challenges of radiology physicians, making the data available right in time is one of the most important benefits of the PACS imaging system, along with many other advantages:

Improved Efficiency and Workflow Management

It‘s only human nature to procrastinate and delay when movement between places is involved. PACS healthcare imaging enables radiology reports to be stored more orderly than digitally. 

Rather than having to sift through a pile of paperwork, physicians can easily access patient files by using the software or simply entering their patient ID or number allocated. 

Enhanced Diagnostic Accuracy and Collaboration

The high-resolution displays and advanced visualization tools on PACS and imaging informatics allow radiologists to analyze images in greater detail, potentially leading to earlier and more precise diagnoses.

Additionally, PACS imaging systems facilitate side-by-side comparisons of current and past photos, which is crucial for tracking disease progression. This translates to reduced errors and faster diagnoses, ultimately improving better and more collaborative patient care.

Reduced Costs and Environmental Impact

Thousands of medical images are taken daily, and their films are developed to read and interpret the data. However, this lengthy process has cons, like cost and environmental impact. 

• Polyester base: This plastic film base can take centuries to break down
• Silver halide emulsion: This layer contains silver particles for image formation and is particularly resistant to degradation.

Considering this, it’s safe to say that digital images are better for the environment and are cost-effective in the long run with sustainable solutions. 

Disaster Recovery and Data Security

PACS healthcare imaging is a cost-effective solution, as printing films is unnecessary. The cloud-based system makes it easy to see images and reports using PACS imaging software. In other words, you save money because you don’t have to pay for film, ink, or printing expenses. What’s more, you save on not paying staff for these services.

Hard copies are more prone to physical damage and could be lost; PACS digital imaging allows immediate access with encrypted images. Only authorized individuals have access to the images, ensuring the protection of ePHI and Prevent Data Breaches.
