Applications
Motorised DICOM-driven positioning — TPS to patient skin
DICOM 3.0/RT TPS workflow
The treatment planning system exports the virtual iso-centre in DICOM RT. The moving laser system reads the DICOM coordinates and drives directly to the planned position — no manual coordinate entry, no transcription error.
CT-simulator patient marking
Radiation therapist loads the TPS plan, presses go, watches the lasers drive to the planned iso-centre on the patient surface, marks the patient. The ±0.2 mm reproducibility means the same marks land in the same place every time.
Virtual iso-centre tattooing
Many plans use a virtual iso-centre offset from the patient surface. The 3- or 5-axis configuration positions the cross-hair at any offset point; tattoo the patient at that exact location.
Five-axis SBRT setup
Stereotactic body radiotherapy plans often use complex multi-axis iso-centres. The five-axis configuration handles non-orthogonal coordinate systems without requiring patient re-orientation on the couch.
Re-simulation mid-treatment
Patient anatomy changes (weight loss, oedema, gas filling) often require re-simulation. The moving system marks the new iso-centre without requiring physical adjustment of fixed lasers in the room.
Multi-modality CT-sim
A CT-sim room used for both megavoltage planning and brachytherapy planning needs flexible laser positioning. The same system serves both workflows — different iso-centre locations driven from the same control interface.
Why Saxsons Moving Laser Positioning System?
±0.2 mm accuracy is five times tighter than the AAPM TG-142 stereotactic-class 1 mm threshold. Same patient marked the same way twice ends up in the same place within ±0.2 mm. The reproducibility that virtual iso-centre tattooing absolutely requires, and that SBRT / SRS planning workflows depend on.
The treatment planning system exports the virtual iso-centre in DICOM RT. The moving laser system reads the DICOM coordinates directly — no manual coordinate entry by the radiation therapist. The transcription-error class of failure is eliminated by removing the transcription.
A single-axis system for routine patient marking; a three-axis for standard radiotherapy workflows; a five-axis for stereotactic and complex-anatomy treatments. The same Saxsons engineering scales from the basic CT-sim to the SBRT-capable theranostic suite.

FAQ
Moving laser positioning — questions we hear from Indian radiotherapy teams
Why virtual-isocentre CT-sim workflows need motorised lasers, what ±0.2 mm reproducibility buys for SBRT/SRS planning, how DICOM integration removes transcription error, and how to pick 1 / 3 / 5-axis configuration.
Q.Why do CT-simulator marking workflows need moving (motorised) lasers rather than fixed lasers?
A fixed laser projects one alignment reference — the machine isocentre. But a treatment plan often uses a virtual isocentre offset from the CT-simulator isocentre — the tumour position is not necessarily at the machine centre. On a fixed-laser system the therapist has to physically move the patient on the couch until the tumour lies at the isocentre, then tattoo. A moving laser drives to the virtual-isocentre coordinates from the TPS and marks the tumour position directly on the patient without shifting them — the mark lands at the exact planned coordinates.
Q.How does ±0.2 mm positioning accuracy translate into real clinical benefit?
AAPM TG-142 stereotactic-class laser tolerance is 1 mm. The Saxsons moving laser delivers ±0.2 mm — five times tighter. The reproducibility that virtual-isocentre tattooing absolutely requires — same patient marked the same way twice ends up in the same physical location within ±0.2 mm — is what SBRT and SRS planning workflows depend on for their setup-error budget. Under-tolerance lasers force the planning margin to expand to swallow the alignment uncertainty.
Q.What does DICOM 3.0/RT integration remove from the CT-sim workflow?
On a manual-entry moving-laser system the therapist reads the virtual-isocentre coordinates from the TPS screen, types them into the laser controller, drives the laser and marks the patient. Every transcription is a potential error source. DICOM 3.0/RT integration exports the virtual-isocentre coordinates from the TPS directly to the laser system — no manual entry, no transcription error. The class of error that comes from typing wrong numbers is eliminated by removing the typing.
Q.When does the department need 1-axis vs 3-axis vs 5-axis configuration?
Single-axis handles routine patient marking where the tumour lies in the coronal plane. Three-axis covers standard radiotherapy workflows where the virtual isocentre needs X / Y / Z translations. Five-axis handles stereotactic SBRT and SRS plans with complex multi-axis iso-centres and non-orthogonal coordinate systems. Configure to your treatment complexity — you don't need to buy the five-axis if the workflow is routine IMRT.
Q.How is the moving laser system supplied and supported in India?
Distributed across India by Saxsons Group. Supply covers the movable laser platform, axis configuration (1 / 3 / 5), DICOM integration with the department's TPS, installation, commissioning against the room isocentre and optional annual position-reproducibility-verification service. Passive Class II red-laser accessory — no AERB licence required for the device itself; CDSCO medical-device import registration handled by Saxsons.
