RayStation

RayStation 8.1 is an advanced software system designed to streamline and enhance radiation therapy by providing comprehensive tools for treatment planning, dose calculation, and analysis using imaging data. It leverages technologies like machine learning, multi-criteria optimization, and deformable registration to create precise, individualized treatment plans, while offering improved usability and computational speed for clinical efficiency.

RayStation 8.1 is a sophisticated software system designed for the comprehensive planning and analysis of radiation therapy treatments. Its primary purpose is to generate precise treatment plans that provide radiation treatment unit set-up parameters and estimate dose distributions for proposed treatments, which are then reviewed and approved by clinically qualified radiation therapy staff before administration. The system integrates various imaging modalities such as CT, PET, and MRI, and allows for configurable functionality based on user needs, ensuring its adaptability to diverse clinical scenarios. The system operates through a detailed workflow that begins with patient data and image import (DICOM), followed by structure definition using advanced contouring tools, and plan setup specifying machine parameters and beam configurations. RayStation 8.1 incorporates advanced computational methods like collapsed cone convolution for dose computation and supports 4D data. Key technological advancements include machine learning for planning and segmentation, multi-criteria optimization, dose tracking, treatment adaptation, and deformable registration, all unified within a single platform. Compared to its predecessor, RayStation 7.0, version 8.1 offers significant improvements in usability, computational speed, and connectivity, while being built on the same core software platform and design principles.
