    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
    A lack of integration leads to errors and uncertainty in CT simulation.

    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 a major source of variability in RT planning5

    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

    49% of patients feel distressed and anxious.9

    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.

    The DirectBrachy positioning board is currently under development; it is not for sale in the U.S.A.

    The DirectBrachy positioning board is not commercially available in all countries. Its future availability cannot be guaranteed.

    The urology stirrups (leg support) seen here are optional. The information contained here refers to products from third party manufacturers and are therefore in their regulatory responsibility.

    The CT simulator and the CT table seen here are not part of the DirectBrachy positioning board.

    DirectBrachy positioning board is only compatible with SOMATOM go.Sim and SOMATOM go.Open Pro with Multi-index RTP Overlay. Afterloader needed for brachytherapy. Shielding of the CT room is required when it its used for brachytherapy.

    Verification of mutual compatibility of medical devices combined in a system in accordance with Article 22 (MDR Regulation (EU) 2017/745) on Medical Devices is pending. The combination is not commercially available in the European Union.

    The DirectBrachy positioning board does not yet fulfill all applicable General Safety and Performance Requirements according to the European Medical Device Regulation 2017/745. The product is not commercially available. Its future availability cannot be guaranteed.
