What is Elekta Unity's Comprehensive Motion Management?
Elekta Unity’s Comprehensive Motion Management (CMM) with True
Tracking and Automatic Gating combines Unity’s diagnostic quality
imaging capabilities with powerful algorithms and technology to
quantify movement and correct for it automatically, as it
happens-ensuring precise and accurate treatment delivery.
Leveraging
the power of the 1.5 T MR, anatomy-specific imaging sequences optimize
the visualization of the target and surrounding healthy tissue.
CMM now enables a safe reduction of treatment margins through a guided workflow with real-time tracking and gating — a critical advancement as we move towards dramatically smaller margins in most of our treatments.”

Why Elekta Unity’s CMM is different to other motion management systems
True Tracking
Accounting for motion whilst delivering the beam is made possible by True Tracking. It continuously tracks the 3D position of any target non-invasively and in real-time. Four strategies can be used for rapid beam gating.
Zero latency
The tracking algorithm enables the prediction of what the tumor will do next. This combined with low system latency gives confidence that the beam is turning on and off when expected.
Intrafraction drift
True Tracking enables the system to move the beam rapidly to compensate for a sustained intrafraction drift. This means when a target moves, the treatment can be adapted without the time penalty of acquiring another 3D image.

Freedom to choose
Multiple approaches, best suited to your patient
Multiple motion management strategies that include free-breathing, breath-hold and exception gating techniques, give the freedom to choose the approach best suited for the patient and indication. Enabling you to deliver truly personalized treatment.

Visual Guidance
Visual Guidance for Unity supports patients in achieving optimal breathing patterns for (CMM), enhancing treatment delivery efficiency. Real-time visual cues assist patients in maintaining breath-hold or guide them through consistent breathing in free-breathing workflows. When no active guidance is needed, a rich selection of calming themes designed to ease anxiety and improve comfort throughout their session can be displayed.
