Introduction

Radiotherapy systems are among the most critical technologies in modern oncology, used to deliver precise doses of radiation for cancer treatment. These systems including linear accelerators, treatment planning systems (TPS), oncology information systems (OIS), and imaging integrations form a highly complex and interconnected ecosystem.

Accuracy, timing, and precision are fundamental in radiotherapy. Even minor deviations in treatment parameters can significantly impact patient outcomes. As these systems become increasingly digital and connected to hospital networks, cloud platforms, and imaging systems, the cybersecurity risk landscape expands considerably.

A cyber vulnerability in a radiotherapy system can lead to manipulation of radiation dosage, disruption of treatment workflows, or exposure of sensitive patient data. Given the life-critical nature of these systems, cybersecurity is not just a technical requirement—it is a patient safety imperative.

Regulatory frameworks such as the European Union Medical Device Regulation (EU MDR) and the U.S. FDA 510(k) pathway require manufacturers to demonstrate robust cybersecurity controls. Security testing plays a vital role in validating that radiotherapy systems are secure, compliant, and resilient.

Cyberintelsys delivers specialized cybersecurity testing services for radiotherapy systems, aligned with global regulatory expectations and industry best practices.

Regulatory Alignment for Radiotherapy System Security

Cybersecurity is a mandatory component of compliance for radiotherapy systems under global regulatory frameworks.

EU MDR (European Union Medical Device Regulation)

EU MDR requires manufacturers to integrate cybersecurity throughout the entire lifecycle of medical devices. For radiotherapy systems, this includes:

• Performing comprehensive cybersecurity risk assessments
• Ensuring secure communication across system components (TPS, OIS, imaging systems)
• Protecting against unauthorized access, tampering, and data breaches
• Maintaining software integrity with secure updates and patch management
• Conducting continuous post-market surveillance and vulnerability management

Manufacturers must document cybersecurity controls within technical documentation, aligned with standards such as ISO 14971 and IEC 62304.

FDA 510(k) Cybersecurity Requirements

For FDA 510(k) submissions, radiotherapy systems must demonstrate a strong cybersecurity posture. The FDA expects:

• End-to-end threat modeling across the entire system ecosystem
• Identification and mitigation of vulnerabilities
• Secure design and development practices
• Software Bill of Materials (SBOM)
• Penetration testing and validation of security controls

Given the high-risk nature of radiotherapy systems, regulators emphasize that cybersecurity risks must not compromise treatment safety or system performance.

Cyberintelsys conducts security testing aligned with these regulatory expectations, ensuring readiness for both EU MDR certification and FDA 510(k) clearance.

Importance of Security Testing for Radiotherapy Systems

Radiotherapy systems operate in highly sensitive clinical environments where cybersecurity directly impacts treatment outcomes and patient safety.

1. Patient Safety and Treatment Accuracy

Unauthorized access or manipulation can alter radiation dosage or treatment plans, leading to underdosing or overdosing. Security testing ensures that treatment parameters remain accurate and protected.

2. Protection of Treatment Planning Data

Radiotherapy relies on detailed imaging and treatment plans. Compromising this data can affect diagnosis and therapy effectiveness.

3. Complex Ecosystem Risks

Radiotherapy systems typically include:

• Linear accelerators (LINAC)
• Treatment Planning Systems (TPS)
• Oncology Information Systems (OIS)
• Imaging systems (CT, MRI)
• Hospital networks and cloud platforms

A vulnerability in any component can impact the entire treatment workflow.

4. Network and Infrastructure Exposure

Connected radiotherapy systems can serve as entry points into hospital networks, increasing the risk of lateral movement and broader cyberattacks.

5. Regulatory Compliance and Market Approval

Failure to meet EU MDR and FDA cybersecurity requirements can result in approval delays, product recalls, and reputational damage.

Security testing ensures that radiotherapy systems remain secure, reliable, and compliant in real-world clinical environments.
