Clear real-time guidance delivers 25¹–40² seconds less setup time per fraction vs. standard SGRT.
What is the Postural Video module?
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.
Two independent, head-to-head studies demonstrate that Postural Video can reduce setup time vs. standard SGRT. In the 2025 study, setup time was reduced by 40 seconds per fraction, and positional accuracy was maintained². In an earlier head-to-head trial, Postural Video cut setup time by 25s / fraction and reduced repeat imaging by 63%.¹
Utilizing the high resolution and fast frame rate of the AlignRT camera pods, the outlines guide to ensure the patient is in the correct position and also helps to quickly identify and correct when a patient does move out of position.
The Postural Video module is only available with AlignRT.
What our customers say
“It is much easier to prepare and edit the patient data in AlignRT Advance. The best feature is the Postural Video module because it allows fast recognition of misalignments. It is a powerful tool to understand exactly where the changes happen when the patient falls outside tolerance during the treatment.”
Dr. Vania Batista, Medical Physicist Heidelberg University Hospital
“There was definitely a time and accuracy advantage with implementing AlignRT Advance, especially with the postural positioning element. It has helped us increase our patient volume without extending our hours or straining our resources and we are still able to maintain a very high-level quality of care, while still keeping our patients comfortable.”
