Presentation
Elekta Evo is a CT-Linac designed to deliver a wide spectrum of ultra‑precision radiotherapy techniques, from routine fractions to highly personalized adaptive treatments. Iris® high‑definition, AI‑enhanced CBCT and the Elekta ONE® platform enable both online and offline adaptive workflows and automation.

Positioning & benefits
One machine expands clinical capability and maximizes existing investment by combining multi‑technique delivery, scalable architecture and integrated software to adopt new adaptive methods at the user’s pace.

Key capabilities

• Multi‑technique delivery: SRS, SBRT, IMRT, VMAT, multiple energies and electrons from a single CT‑Linac.
• Iris® imaging: high‑definition, AI‑enhanced CBCT with AI‑driven scatter correction and next‑generation reconstruction for improved contrast and HU accuracy.
• Adaptive toolkit via Elekta ONE® | Online: online/offline adaptive workflows, auto‑contouring, plan adaptation and end‑to‑end QA.
• Workflow automation: zero‑click contouring and dose QA, one‑click patient selection, single sign‑on and GPU‑based parallel processing.
• Support options: Elekta Care service offerings for uptime, training and lifecycle support.

Clinical & operational messaging
Evo supports personalized per‑fraction care with improved imaging clarity, enables refinement of IGRT workflows and streamlines offline adaptive processes while providing a unified software experience and dedicated support to maximize throughput.

Imaging: Iris highlights
Iris® delivers AI‑enhanced CBCT with scatter correction and enhanced contrast to visualize targets and nearby healthy tissue more clearly, improving HU fidelity for planning and adaptation. Comparative images demonstrate improved clarity over conventional CT.

Treatment delivery & performance
Design features target high conformity and fast delivery: virtual leaf‑width equivalence for improved conformity, low‑leakage high‑definition MLC, fast leaf and jaw speeds, High Dose Rate modes (6 FFF at 1400 MU/min, 10 FFF at 2200 MU/min), 40 x 40 cm field and VMAT with IntelliBeam for accelerated delivery (page cites up to ~70% faster VMAT).

Regulatory & availability note
*Elekta Evo has CE mark and U.S. FDA 510(k) clearance with limited global availability.
