Our market-leading SGRT solution

What is AlignRT?

AlignRT® is a system that tracks a patient’s position before and during radiation therapy, to aid in setup and treatment accuracy. Using proprietary 3D stereo camera units, AlignRT tracks the skin’s surface and compares it to the ideal position with submillimetric† accuracy. AlignRT can automatically signal for the treatment delivery system to pause radiation if the patient moves out of the desired position, and there is no need for tattoos or permanent marks.

AlignRT has been shown to help deliver this “optimal patient positioning”, across many different cancer treatment sites, and is commonly used for “Deep Inspiration Breath-hold”.  Vision RT systems are deployed in all 15 of the top 15 US News “Best Hospitals for Cancer*” and have been extensively studied with more than 100 published clinical studies. We have comprehensive interoperability and assured long-term collaboration with both major linac vendors.

AlignRT has been shown to help deliver “optimal patient positioning”, across many different cancer treatment sites. Many clinics first adopt SGRT because of its advantages in delivering Deep Inspiration Breath-hold treatments, but it can be used for every patient and for every fraction. There are already more than 250 peer-reviewed clinical studies on the effectiveness of SGRT with AlignRT and Vision RT’s systems are being used in all 15 of the top 15 US News “Best Hospitals for Cancer*”

We have comprehensive interoperability and assured long-term collaboration with both of the major linac vendors.

Every patient, every fraction

AlignRT is safe, non-invasive and can be used for fast and accurate patient setup and monitoring for all forms of cancer, including:

Control the tech, focus on the patient

Reduced Treatment Time

AlignRT is proven to save time and reduce imaging. Northside Hospital Cancer Institute (NHCI) reduced patient treatment time by 50%  due to less repeat imaging and more accurate initial setup with AlignRT.


There are multiple peer-reviewed papers that demonstrate how AlignRT enables sub-mm, and sub-degree accuracy through the entire treatment process across indications including DIBH, SRS, SBRT, pelvis and sarcoma.

Increased patient comfort

AlignRT can eliminate the need for permanent marks or tattoos and reduces the need for pediatrics anesthesia. Currently, more than 100 centers across the world have gone tattoo and mark-free with AlignRT.

"A Wise Investment"

A recent oncology technology brief from the Advisory Board’s health care think tank (with 4,500 member organizations) recommended the use of SGRT as a “wise investment” for cancer centers.

10 ways SGRT with AlignRT can help your clinical practice

1. Automatic Beam-Hold

AlignRT offers automatic beam-hold on all Linac platforms if the patient moves or rotates in any direction.


2. Reliable Detection

Continuous monitoring through the entire treatment process, ensuring reliable detection of any clinically relevant movement; including pre, during and post-verification imaging.


3. Peer-Reviewed Data

Peer-reviewed, published data on AlignRT, showing it offers equivalent accuracy to other solutions; including systems which rely on additional internal imaging.


4. Four-Week Training Program

We offer a four-week installation and training program, run by a team with clinical experience. We will be with you, on-site, when you go live.


5. Peer-to-Peer Learning Opportunities

You will have access to free online courses and the chance to join an active SGRT Community to connect with your peers. We also offer a mentorship program where you can learn from centers already using SGRT.


6. Best-in-Class Support Team

Our sole aim is to provide minimum disruption and maximum effectiveness for your team and the system you’ve invested in. Our support has been rated “best in class” in the radiation oncology space.


7. Patient Comfort

AlignRT is completely contactless and doesn’t require additional immobilization or fixation. This helps with infection prevention and means less anxiety and more comfort for your patients.


8. Accuracy & Tattoo-free

With a simple and efficient workflow, AlignRT enables quicker and more accurate set-ups, which means your center can treat more patients every day. Less time in treatment, along with the option to forgo marks or tattoos means more patient satisfaction.


9. Integration with all R&V systems

AlignRT is fully integrated with all R&V systems; allowing quick, seamless data transfer and automatic patient selection. You will be able to place patients at isocentre more quickly and with less manual handling, thanks to AlignRT’s automated couch movements. This also means intra-fraction corrections can be applied automatically, from outside the treatment room.


10. AlignRT Can Be Used On All Sites

We offer business case support and flexible financing options. AlignRT can be used for multiple indications, with similar workflows, making it a sound investment for your clinical practice.
