It will give you everything you need to achieve the ultimate starting point for optimal RT planning, and will help you produce the most successful outcomes possible.

    Be certain in simulation

    The challenges in CT Simulation.

    60% of all RT incidents are caused by manual operation and data exchange4

    • Successful CT simulation needs efficient and fail-safe workflows
    • Current processes mean users have to switch between multiple software and hardware solutions

     

    Streamlined workflows reduce sources of errors

    Lack of integration leads to errors and uncertainty in CT simulation.

    Our solution: Go for a trendsetting mobile workflow

    Integration is a key factor to avoid potential error-prone CT simulation workflows

    SOMATOM go.Sim comes with fully integrated hardware and software tailored specifically to your requirements. It offers unparalleled operational flexibility, and intuitive guidance.

    Drive precision for contouring

    Poor scope for accurate contouring hinders confident treatment planning

    • Modern treatment techniques require precise planning
    • CT simulation must consistently deliver high-quality patient modeling for the tumor and surrounding organs
    • Yet the data provided for contouring are often not precise enough
    Contouring is the main cause of variability

    Contouring is a major source of variability in RT planning6

    Drive precision for OAR contouring

    Suboptimal image quality leads to suboptimal autocontouring

    Radiation oncology professionals have to spend time manually correcting poor autocontouring

    • The quality of autocontouring depends on the quality of the CT images
    • Suboptimal image quality (caused by metal artifacts, poor soft-tissue contrast, etc.) leads to suboptimal autocontouring7,8
    OAR contouring is very time-consuming

    In the worst-case scenario, radiation oncology professionals have to redo the OAR contouring entirely by hand.

    Consistent OAR contours generated directly by the CT simulator with DirectORGANS3

    SOMATOM go.Sim features DirectORGANS3 (Optimized Reconstruction based contours trained by Generative Adversarial Networks) an AI-powered OAR contouring that automates and standardizes key steps in the CT simulation pathway. The high-quality information arrives directly as TPS-ready data.

    An autocontouring algorithm needs a specific type of image to perform contouring

    DirectORGANS3 optimizes the images specifically for the algorithm.
    This paves the way for consistent OAR contouring powered by AI.

    AI Siemens Healthineers

    DirectORGANS3 is a revolutionary, AI-based OAR contouring solution. The result reduces unwarranted variations with high-quality contours that approach the level of consensus-based contours. It leverages optimized and standardized reconstruction parameters to deliver input to the deep learning based contouring solution.

    Your benefits

    • OAR contouring directly in the system, no need for manual interaction
    • Optimized images designed for the deep-learning algorithm
    • High-quality contours that approach the level of consensus-based contours

    Drive precision in target contouring

    A powerful combination of three innovative solutions delivers confident tumor visualization, precise target contours, and a straightforward 4D workflow: iMAR3 reduces metal artifacts, DirectDensity2,3 unlocks optimal kV settings with a single calibration curve, and Respiratory Motion Management3 optimizes scan parameters based on the patient’s breathing.

    Your benefits

    • Confident tumor visualization thanks to automated metal artifact reduction with iMAR3
    • Precise target contours with optimum kV imaging and a single calibration curve thank to DirectDensity2,3
    • Straightforward 4D workflow thanks to comprehensive respiratory motion management3
    DirectDensity2,3 unlocks a wider range of tube voltages in CT scanners for better imaging quality while maintaining similar dosimetric accuracy.9

    Care for patients and users

    Dialysis Treatment Patient

    Anxious patients and time-pressured operators can lead to suboptimal CT simulation

    • Current CT simulation can create anxiety for patients and pressure for operators
    • Operators have to spend a lot of time outside the examination room
    • Installing and maintaining a multi-vendor system is complex and time-consuming
    CT simulation can create anxiety for patients and pressure for operators

    49% of patients feel distressed and anxious.10

    If operators are under less time pressure, they can devote more time to caring for patients and generating high-quality results. If patients feel at ease, their CT simulation will be more successful.

    Improved patient experience through patient-centric design

    Improve the patient experience with a patient centric design, co-created with RT professionals

    • Total freedom over how and where you set up the simulation, and more time with your patient thanks to the mobile workflow

    As shown by measurements with a Gammex 467 Tissue Characterization Phantom comparing [T]standard reconstruction and DirectDensity reconstruction. Image value to relative electron/mass density conversion for the standard reconstruction was based on a two-linear-equations approach with individual calibration for each tube voltage. For DirectDensity images, a single tube-voltage-independent linear conversion was used.

    DirectDensity reconstruction is designed for use in Radiation Therapy Planning (RTP) only. DirectDensity reconstruction is not intended to be used for diagnostic imaging.
