If you work with the Elekta Versa HD linear accelerator, you know it’s a powerful system for advanced radiotherapy (VMAT, SBRT, SRS). But finding the right manual—or knowing which one you actually need—can be challenging. This post cuts through the confusion.
Request access through your facility’s Medical Physics Director. Never use scanned or photocopied manuals from third-party sites; they are often outdated by 2–3 revisions.
Target Audience: Clinical users (RTTs), medical physicists, service engineers
Document ID: Elekta 4513370 81 01 (example)
Format: PDF, ~450 pages
The Elekta Versa HD user manual is more than a binder on a shelf; it is the single source of truth for safe, effective, and efficient radiation therapy. Whether you are troubleshooting a E-415 MLC error, executing a high-dose FFF SBRT plan, or performing monthly QA, the manual provides the authoritative answer.
Remember: Always use the manual revision that matches your machine’s software version. As of 2025, Integrity v.4.4 is the current standard. Bookmark the error code appendix, memorize the emergency beam-off locations, and keep a laminated quick-reference guide at the console. Your patients’ outcomes depend on it.

The Elekta Versa HD is a versatile digital linear accelerator (linac) designed for a wide range of radiation therapy techniques, from conventional treatments to advanced stereotactic radiosurgery (SRS) and stereotactic body radiotherapy (SBRT). elekta versa hd user manual
Official documentation and technical guides can be found at the Elekta Product Documentation Library or within the Elekta Care Community portal. Core Components & Features
The Versa HD integrates several advanced subsystems to ensure precision and efficiency:
Agility™ 160 Multileaf Collimator (MLC): Features 160 motorized leaves with fast speeds (up to 6.5 cm/s) and exceptionally low interleaf leakage (less than 0.5%), allowing for highly modulated beams and better organ-at-risk (OAR) sparing.
Flattening Filter-Free (FFF) Beams: Capable of delivering high dose rates (up to 2400 MU/min for 10 MV FFF), which significantly reduces treatment times for complex SRS/SBRT cases.
Imaging Capabilities: Includes the XVI (X-ray Volume Imaging) system for 2D, 3D, and real-time 4D cone-beam CT (CBCT), enabling motion management for tumors in the lung or prostate without needing implanted markers.
HexaPOD™ evo RT Couch: A robotic patient positioning system with six degrees of freedom (6DOF) to exactly align patients with radiation beams. Operational Guidelines for Clinical Users Technical Documentation
The Elekta Versa HD is a sophisticated digital linear accelerator designed for high-definition dynamic radiosurgery (HDRS) and conventional radiotherapy. The user manual and technical reference guides detail its operation across complex treatment modalities like Stereotactic Radiosurgery (SRS) and Stereotactic Body Radiation Therapy (SBRT). Core System Features If you work with the Elekta Versa HD
Agility™ Multileaf Collimator (MLC): Equipped with 160 motorized leaves (80 pairs) providing 5 mm leaf width at the isocenter and a 1 mm virtual leaf width for high-conformal beam shaping.
Flattening Filter-Free (FFF) Beams: Capable of delivering high dose rates—up to 1400 MU/min for 6 MV FFF and 2400 MU/min for 10 MV FFF—to significantly reduce treatment times.
Advanced Motion Management: Features 4D Cone Beam CT (CBCT) for real-time tracking of moving tumors, such as those in the lungs or prostate, without needing implanted markers.
HexaPOD Robotic Couch: Provides submillimeter positioning accuracy in six degrees of freedom (x, y, z plus roll, pitch, and yaw). Commissioning an Elekta Versa HD linear accelerator - PMC

beams (6 and 10 MV-FFF) for high dose rates—up to 2,400 MU/min. Electron beams range from 4 to 15 MeV. Agility™ 160-leaf MLC
: Features 160 motorized tungsten leaves (80 pairs) with a 5 mm leaf width at the isocenter. It achieves leaf speeds up to and remarkably low leakage (less than 0.5%). Beam Shaping : Utilizes sculpted diaphragms for a maximum field size of
cm. The system supports a "virtual" 1 mm leaf width through precise jaw positioning. 2. Advanced Imaging & Motion Management
