Experience Unmatched Precision and Efficiency in Proton Therapy with SGRT
Proton therapy’s strength is its ability to deliver radiation directly to tumors near critical organs, sparing surrounding healthy tissue. This precision demands extremely accurate patient positioning – even more so than with photon therapy – as minor misalignments can impact treatment effectiveness.
AlignRT enhances proton therapy by offering patient setup and tracking accuracy within 0.5mm, ensuring optimal alignment throughout the treatment process. With AlignRT, you can enhance both patient setups and intra-fraction monitoring to deliver unparalleled treatment accuracy and efficiency.
AlignRT, alongside Postural Video‘s high resolution and fast frame rate, helps reduce setup times by 29% compared to standard SGRT and reduce repeat imaging by 63%¹.
AlignRT is operational with proton systems manufactured by Hitachi*, IBA*, Varian, and Mevion.
*Gating interface is currently available on selected models.
More than 60 clinics globally are already using AlignRT for proton.
MapRT for Proton Therapy*
Clearance mapping for advanced proton planning
MapRT helps to make treatments fast, easy and safe. It uses SGRT to deliver a “clearance map”, which planners use to check which beams are deliverable during plan creation.
Better Plans Made Easy.
- Check treatment clearances before sim.
- Potentially improve dose plan using clearance map beam options.
- Avoid dry runs and replans for non-deliverable plans.
*In development.
Clinical Evidence on Proton Treatments with SGRT:
Published data shows the use of AlignRT with Proton Therapy for various treatment indications, including pelvis, limb, chest and spine, and demonstrated:
| “The use of surface imaging allows postmastectomy chest wall patients to be positioned more accurately and substantially more efficiently than radiograph only-based techniques²”. |  |
Research on the feasibility and reliability of optical surface imaging in proton therapy has shown its ability to accurately measure air gaps and SSD, providing an efficient method to verify target depth during treatment.³.
Research found that combining initial and weekly X-ray acquisition with daily surface imaging is effective for routine PMRT positioning and monitoring changes in the treatment area⁴.
A study comparing the dosimetric accuracy of proton breast treatment plans using SGRT and CBCT setups supports the daily use of SGRT to ensure precise dose delivery in proton breast therapy⁵.
Evidence from Qubala et al shows that SGRT significantly reduces setup time, and reimaging frequency, and enhances workflow efficiency. Additionally, optimized ROI design further improves positioning reliability with SGRT⁶.
Proton workflow with SGRT:
Sim
Helping to eliminate physical markers, belts, or blocks, SimRT offers non-invasive, non-ionizing, accurate patient positioning, reducing discomfort and the risk of damaging healthy tissue.
Plan
MapRT helps to make non-coplanar treatments fast, easy and safe. It uses SGRT to deliver a “clearance map”, which planners use to check which beams are deliverable during plan creation.
Treat
If a patient moves out of position, AlignRT can automatically signal the system to pause treatment, typically within 50-100ms. The Postural Video module gives you a multi-angle, real-time view of the patient’s overall alignment relative to their reference position during setup and monitoring by using an outline of the reference surface and a live video stream of the patient.
