Advanced Commissioning and High-Precision Dosimetry for Multi-Target SRS, SBRT, and Adaptive Radiotherapy

Core Focus: Multi-Target Radiosurgery

Most commissioning processes establish baseline functionality. Fewer address the limits of accuracy for small off-axis targets, and multi-target stereotactic treatments. Default beam modeling parameters recommended by the manufacturer are often not well suited to achieve optimal dosimetric accuracy for these cases.

We offer services and guidance for multi-target SRS programs, including:

  • Guidance and mentoring for clinics updating or implementing a new SRS/SBRT program, or working to improve dosimetry for all multi-target scenarios

  • Beam data collection & validation for central and off axis small fields

  • Beam modeling to achieve accurate dosimetry for all multi-target clinical scenarios

  • End-to-end validation strategies

  • Image guidance and immobilization strategies

  • Strategies for accurate, robust, & efficient pre-treatment QA, independent dose calculation, & routine linear accelerator and TPS QA

  • Development of Standard Operating Procedures & Documentation

Flexible Support to Meet Your Needs

Every clinic’s path to a robust SRS program is different. Whether you are launching a new program, expanding existing capabilities, addressing dosimetry or workflow challenges, or seeking independent review, Axis Radiotherapy Physics provides scalable support tailored to your institution’s goals, resources, and level of experience.

We support new and developing SRS/SBRT programs as well as established centers seeking additional expertise, independent review, or workflow optimization. Services are designed to be flexible and practical, with solutions adapted to the clinical and operational realities of each institution. Engagements may range from a single workflow review or technical consultation to ongoing collaboration for full program development.

Axis Radiotherapy Physics collaborates with community clinics, academic centers, and international institutions to help develop safe, efficient, and sustainable stereotactic radiotherapy programs. Remote-first support options are available where appropriate, allowing institutions to access specialized expertise in a cost-effective and efficient manner.

Support may include:

  • Remote consultation and mentorship

  • Independent workflow and treatment planning review

  • SRS/SBRT commissioning support

  • Small-field dosimetry and beam modeling guidance

  • End-to-end testing and validation

  • Adaptive radiotherapy workflow implementation

  • Protocol, QA, and documentation development

  • Staff education and training

  • On-site or remote collaboration

Services can range from focused guidance on specific challenges to comprehensive support for full program development and implementation. Our goal is to help clinics build confident, reliable, and clinically practical SRS programs — regardless of program size, geography, or starting point.

Adaptive Radiotherapy

Adaptive radiotherapy requires robust integration of imaging, planning, delivery, and QA workflows. Axis Radiotherapy Physics provides support for commissioning, validation, and implementation of adaptive treatment programs, with an emphasis on practical clinical workflows and independent verification.

Stereotactic Body Radiation Therapy (SBRT):

SBRT demands accurate treatment delivery under challenging motion, imaging, and dosimetric conditions. Axis Radiotherapy Physics provides support for commissioning, validation, and implementation of SBRT programs, with emphasis on workflow reliability, motion management, and independent verification.
