RT2O2

Enterprise imaging

• is a comprehensive approach to managing medical images and associated data across various specialties and departments within a healthcare network, e.g., radiology, cardiology, and pathology

• aims to consolidate and standardize medical images and data, making them accessible, interoperable, and seamlessly integrated into electronic health records (EHR) or electronic medical record (EMR) systems.

X-ray

Uses a small amount of radiation to create images of the body’s structures, particularly bones, and is used to diagnose fractures, arthritis, and infections

Computed Tomography

Uses a series of X-ray images to create detailed cross-sections of the body, helping to diagnose tumors, cardiovascular diseases, and internal injuries.

Magnetic Resonance Imaging

Uses magnetic fields and radio waves to produce highly detailed images of soft tissues without radiation, used to diagnose neurological conditions, soft tissue injuries, and more.

Nuclear Medicine

Involves the use of small amounts of radioactive material to help diagnose and treat disease by showing how organs and tissues are functioning. Examples include PET (Positron Emission Tomography) and SPECT (Single-Photon Emission Computed Tomography).

Ultrasound

Uses high-frequency sound waves to create images of internal organs, blood vessels, and a fetus. It is used in areas like obstetrics, cardiology, and to check for gallbladder disease

Mammography

A specialized type of X-ray to examine breast tissue, used for screening and diagnosing breast cancer.

Interventional Radiography

Uses real-time video X-rays to guide minimally invasive procedures like biopsies or the insertion of stents and catheters.

Endoscopy and Colonoscopy

Uses a long, flexible tube with a camera to look inside the body.

Computers

An integral part of many activities within the Radiology Department. Used by different radiologic modalities to acquire, process, and post-process imaging data.

Radiology Information Systems

are computer systems that manage medical imaging data and related information within a healthcare organization.

1. Standalone RIS

2. Integrated RIS

3. Web-based RIS

4. Cloud-based RIS

5. Mobile RIS

Different types of Radiology Information Systems

Standalone RIS

These systems are designed to handle the scheduling and tracking of radiology examinations and patient information management within a single department or facility.

Integrated RIS

These systems are designed to integrate with other healthcare information systems, such as electronic medical records (EMR) and picture archiving and communication systems (PACS), to provide a more comprehensive view of a patient' s medical history and care.

Web-based RIS

These systems use a web browser to access the RIS system, allowing users to access the system from any location with an internet connection.

Cloud-based RIS

These systems are hosted on remote servers and accessed through the internet, allowing healthcare organizations to outsource the management and maintenance of the RIS system to a third party

Mobile RIS

These systems are designed for use on mobile devices, such as smartphones and tablets, and allow users to access and manage radiology information while on the go.

Integrations that RIS software should have:

Electronic Health Records

It stores all vital patient information. Integrating the RIS with this ensures that all medical images are shared directly with the physician who ordered them.

Digital Imaging and Communications in Medicine

A set of software and hardware used to take X-rays. It’s a standard protocol used internationally for image management and processing.

Health Level Seven (HL7)

It is used to transfer clinical and administrative data between different healthcare software applications.

The Enterprise Master Patient Index (EMPI)

It is a patient database that helps healthcare organizations store and share accurate patient information.

Picture Archiving and Communication Systems (PACS)

helps store, retrieve, and manage radiology images. Integrating RIS with this ensures streamlined access, routing, and archiving of images.

Billing and Reimbursement System

To ensure billing and reimbursement claims are accurate, RIS can integrate with supportive billing systems. This also reduces errors and ensures bills are paid on time.

Patient portals

When you integrate your RIS with this, patients can easily access their results, increasing patient engagement and satisfaction.

1. Spectra RIS

2. ADS RIS

3. Medics RIS

Commercial RIS Software

Spectra RIS

A commercial system that supports efficient exam workflows, image access, and reporting. Availability may vary by region, and it integrates with other RIS/EMR solutions in other markets.

ADS RIS

A commercial RIS offering features like claim submissions, report attachment, and attorney portals for handling workers ' compensation claims.

Medics RIS

A commercial system that provides comprehensive workflow management, including patient scheduling, insurance verification, and billing.

1. Star Topology

2. Mesh Topology

3. Hybrid Topolgy

Network Architecture Topology

Star Topology

All devices (workstations, servers, imaging devices) are connected to a central hub or switch.

Easy to manage and troubleshoot, scalable, and if one link fails, it doesn’t affect the others.

Commonly used in radiology departments where multiple imaging devices and PACS servers need to be interconnected.

Mesh Topology

Devices are interconnected, with multiple paths for data to travel.

High redundancy and reliability, as multiple paths ensure no single point of failure.

suitable for large hospital networks where uninterrupted access to imaging data is critical.

Hybrid Topology

Combines elements of star, mesh, and other topologies to meet specific requirements.

Flexible, scalable, and can be tailored to the specific needs of a radiology department.

Often used in modern healthcare facilities to balance performance, reliability, and cost.

PROTOCOLS FOR RADIOLOGY:

DICOM (Digital Imaging and Communications in Medicine)

The international standard for transmitting, storing, and sharing medical images and related information.

Ensures interoperability between different imaging devices and systems, supports image compression, and includes patient information.

Essential for communication between imaging devices (e.g., CT, MRI, X-ray machines) and PACS.

PROTOCOLS FOR RADIOLOGY:
HL7 (Health Level Seven)

A set of international standards for the exchange, integration, sharing, and retrieval of electronic health information.

Facilitates the integration of various healthcare systems, including EHR (Electronic Health Records) and RIS (Radiology Information Systems).

Used for exchanging patient information, orders, and results between radiology and other clinical systems

PROTOCOLS FOR RADIOLOGY:

FHIR (Fast Healthcare Interoperability Resources)

A standard describing data formats and elements (known as " resources ") and an API for exchanging EHR.

Modern, web-based approach to interoperability supports RESTful APIs.

Increasingly used for integrating radiology data with other healthcare systems.

PROTOCOLS FOR RADIOLOGY:
TCP/IP (Transmission Control Protocol/Internet Protocol)

The fundamental protocol suite for data transmission over the Internet and most local networks.

Ensures reliable data transfer, error checking, and data integrity.

Underpins the network communication for transmitting DICOM images and HL7 messages.

PROTOCOLS FOR RADIOLOGY:
HTTPS (Hypertext Transfer Protocol Secure)

An extension of HTTP with encryption for secure communication over a computer network.

Uses SSL/TLS to encrypt data, ensuring privacy and data integrity.

Essential for secure access to web-based PACS and teleradiology systems.

PROTOCOLS FOR RADIOLGY:
VPN (Virtual Private Network)

Creates a secure connection over a less secure network, such as the internet.

Encrypts data, ensuring secure remote access to radiology systems.

Used by radiologists to securely access PACS from remote locations.

PROTOCOLS FOR RADIOLOGY:

LDAP (Lightweight Directory Access Protocol)

A protocol for accessing and maintaining distributed directory information services.

Centralizes authentication and directory services.

Manages user access and permissions for radiology systems
