RT Elements (4.5)
Overview
RT Elements (4.5) is an advanced software platform for radiation therapy treatment planning, developed by Brainlab AG. It is designed to assist medical professionals, including radiation oncologists, medical physicists, and neurosurgeons, in creating precise and efficient treatment plans for various lesions. The system leverages AI and machine learning for tasks such as tumor segmentation, enhancing the accuracy and speed of contouring and dose optimization.
The software provides a comprehensive suite of applications, including tools for multiple brain metastases radiosurgery (SRS), cranial SRS, spine SRS, and a general RT Planning Platform. Key functionalities encompass dose review, retreatment review, and advanced segmentation capabilities for anatomical regions like cranial, basal ganglia, head & neck, pelvic, spine, and extracranial areas.
RT Elements (4.5) aims to streamline workflows, spare organs at risk, and deliver highly conformal radiation doses, ultimately improving patient outcomes in stereotactic, conformal, and Linac-based radiation treatments.

What Physicians Need to Know
Familiarize yourself with the AI/ML-powered cranial tumor segmentation to potentially expedite contouring workflows. Leverage the 'Retreatment Review' for comprehensive patient history when managing recurrent metastases. Utilize the advanced optimization tools and predefined templates to standardize and streamline your SRS planning. Consider attending Brainlab Academy courses to refine your skills, especially for complex radiosurgery cases and advanced plan optimization techniques. Ensure your team is adequately trained to maximize the benefits of the software's advanced features and to correctly interpret the processed images.
RT Elements 4.5 is designed for broad integration within the Brainlab ecosystem, including seamless connections with Curve™ Image Guided Surgery and Buzz® Digital O.R. It also offers an interface to third-party contouring systems like Art-Plan for extracranial workflows. For optimal end-to-end workflow and precise patient positioning, integrate with Brainlab's ExacTrac System. The platform's compatibility with mobile devices and workstations facilitates collaborative planning and review across different departments and locations.
