Why Standard 3-Axis Systems limit OEM competitiveness in Radiotherapy
Modern radiotherapy demands sub-millimeter precision and workflow flexibility. Yet many LINAC setups still rely on 3-axis couches that restrict positioning capabilities and integration potential.
The following challenges illustrate why these limitations can affect system performance, market positioning, and clinical versatility for OEMs.
Limited Motion Control for Advanced Treatments
Standard couches offer only translational and vertical movement.
Without angular correction (pitch, roll, yaw), precise isocenter alignment in stereotactic or non-coplanar beam setups becomes difficult — reducing the LINAC’s suitability for high-precision applications.
Constrained Integration with Imaging and Guidance Systems
3-axis positioning limits real-time correction after image verification (e.g. CBCT).
This restricts compatibility with adaptive workflows and image-guided radiotherapy (IGRT) concepts that are now expected by clinics investing in premium systems.
Reduced Appeal in Competitive Tenders
As clinical centers increasingly demand 6DoF capability for new installations, LINAC systems without it are harder to differentiate.
Lack of motion correction options can make an OEM’s product appear less future-ready and less aligned with emerging treatment standards.
High Upgrade Costs and Downtime
Retrofitting standard tables often requires mechanical redesign or software adaptation within the LINAC architecture.
This increases engineering effort, slows time-to-market, and raises system costs — limiting flexibility in responding to new clinical requirements.
