IEC 62083:2025

Overview

IEC 62083:2025 is the International Electrotechnical Commission (IEC) standard that specifies the safety requirements for medical device software used in radiotherapy treatment planning systems (RTPS). This standard focuses on the design, manufacture, installation, and maintenance of software that enables healthcare professionals to plan radiotherapy treatments, ensuring accurate and safe delivery of radiation therapy.

The latest 2025 edition brings a technical revision, reflecting the evolving landscape of radiotherapy planning technology. Key enhancements include the explicit addition of adaptive radiotherapy, updated terminology to match current implementations, and enhanced guidance on software communication with other medical devices. The standard applies to both standalone and integrated software systems used in the creation, evaluation, or approval of radiotherapy treatment plans.

Key Topics

• Software Safety Requirements: Defines mandatory safety protocols for treatment planning software, addressing risk management, algorithm validation, data integrity, and user documentation.
• Communication and Interoperability: Sets out requirements for the import and export of data between the RTPS, imaging systems, delivery machines, and other clinical devices.
• Type and Site Testing: Ensures that both manufacturer and on-site tests are conducted to validate the correct installation and ongoing safety of RTPS, as well as its performance in the clinical environment.
• Data Security and Access Control: Specifies measures to protect patient data, manage software updates, and prevent unauthorized use or modification.
• Adaptive Radiotherapy: Introduces specific requirements for systems supporting adaptive radiotherapy workflows, including offline, online, and real-time adaptation capabilities.
• User Qualifications and Environmental Conditions: RTPS must be designed for use by qualified professionals within specified environmental parameters, supported by comprehensive instructions for use.

Applications

IEC 62083:2025 is essential for:

• Manufacturers: Guiding compliance in the development, testing, and documentation of radiotherapy planning software to meet international safety standards.
• Healthcare Providers: Ensuring that selected RTPS solutions adhere to robust safety and data management protocols, minimizing risks to patients and clinicians.
• Installers and Maintenance Teams: Standardizing procedures for the safe installation and maintenance of clinical RTPS, including ensuring system integrity and interoperability.
• Regulatory Authorities: Providing a benchmark for the approval and auditing of radiotherapy planning software in line with global best practices for medical device safety.

This standard is relevant to software used in creating radiotherapy prescriptions, anatomical image registration, contouring, dose calculation, plan evaluation, and quality assurance. Whether the RTPS is a standalone system or integrated with treatment delivery equipment, IEC 62083:2025 supports a consistent framework for safety and performance.
