Indications for Use
The intended use of syngo® Dosimetrist Workspace is as an accessory to the linear accelerator system to aid and support in the planning of delivery of x-ray photon and electron radiation for the therapeutic treatment of cancer. The syngo® Dosimetrist Workspace v2.7 is a comprehensive oncology workflow software package that allows for both CT simulation as well as inverse radiation therapy treatment planning and optimization to aid in the oncology clinical workflow where indicated. The syngo® Dosimetrist workspace is comprised of two major components, the CT Simulation component (VSIM) and the inverse radiation therapy treatment planning component (KonRad) to be used in the creation, modification, evaluation and approval of radiation treatment plans. The VSIM component permits CT simulation to be performed on the syngo® Dosimetrist workstation. The CT scans are imported into the VSIM software component and the user is able to create three-dimensional models of targets and organs. The VSIM application supports the use of automatic contouring and segmentation or a model based segmentation (MBS) library of anatomical regions may be used. The contours and segmentation can be manually adjusted prior to use by the treatment planning system. Additionally, the user is able to identify the patient isocenter, place treatment beams, and identify beam modifiers (blocks, apertures, and MLCs). The simulation is then available for radiation treatment planning for dose calculation via the KonRad software component or other treatment planning systems. The plans are then reviewed and approved by the clinician prior to transfer to the delivery system for the actual treatment. The KonRad software component is intended to optimize multi-leaf (MLC) positions or partial attenuation block shapes for intensity modulated external beam radiation therapy (IMRT). Once the optimization is complete, the dose distribution and dose volume histogram curves are displayed for the user to evaluate. After approval, the results are exported to the delivery equipment, linear accelerator, or record and verify system, for final verification prior to treatment delivery. The KonRad TPS software component allows for efficient inverse radiation therapy treatment planning and optimization.

# Description Summary for the syngo® Dosimetrist Workspace:
### Technoloqical Characteristics:
Zhe syngo® Dosimetrist Workspace v2.7 supports configuration of both a Virtual Simulation
[VSIM] and a Treatment Planning System [TPS] called KonRad™. The syngo® Dosimetrist Workspace v2.7 is based on the currently cleared SIEMENS COHERENCE™ Dosimetrist Workspace v2.2 and is intended to be marketed as an update. The basic design, safety features and function of the Dosimetrist Workspace v2.7 remain unchanged from their currently cleared intended use and functions.
The syngo® Dosimetrist Workspace v2.7 supports the visualization and clinical assessment of the treatment area using a variety of digital images. The VSIM application supports a three dimensional graphical representation allowing for a virtual setup and treatment of the patient without involving the patient. A variety of software tools are supplied to assist in the delineation of structures for rapid contouring plus segmentation tools for beam profiles and placement on target organ(s) or structures prior to the use by the treatment planning function ITPS1.
New features for the VSIM module are the Advanced Segmentation application for rapid contouring and segmentation using the Random Walker algorithm. Additionally, the contouring process can be assisted by the use of Model Based Segmentation for the prostate, bladder, rectum and femurs/hips based on anatomical libraries.
The syngo® Dosimetrist Workspace v2.7, when configured with the KonRad inverse planning system, is a radiation therapy treatment planning package designed to optimize multi-leaf collimator (MLC) positions or partial attenuation block shapes for intensity modulated external beam radiation therapy (IMRT). The KonRad component uses the defined anatomical structures for the optimization and treatment planning process.
The final treatment plan can be exported to the appropriate delivery equipment such as a medical linear accelerator, and/or record and verify system. The final treatment plan does not activate the radiation therapy delivery equipment, as all information must be verified by the user prior to the initiation of radiation therapy treatment. The approved treatment plan facilitates the delivery of radiation to defined target volumes while sparing surrounding normal tissue and critical organs from excess radiation using the conventional linear accelerator.
### Syngo®:
The syngo® Dosimetrist Workspace v2.7 software utilizes the syngo® software architecture and allows for a standardized graphical user interface across Siemens medical products. The syngo® -based software design consists of task cards allowing for a selection of modules of common software applications for image acquisition, reconstruction, post-processing, display, and archiving across the Siemens medical product lines. -

The syngo® Dosimetrist Workspace v2.7 is a comprehensive oncology workflow software package that allows for both CT simulation as well as inverse radiation therapy treatment planning and optimization to aid in the oncology clinical workflow where indicated. The syngo® Dosimetrist workspace is comprised of two major components, the CT Simulation component (VSIM) and the inverse radiation therapy treatment planning component (KonRad) to be used in the creation, modification, evaluation and approval of radiation treatment plans.
The VSIM component permits CT simulation to be performed on the syngo® Dosimetrist workstation. The CT scans are imported into the VSIM software component and the user is able to create three-dimensional models of targets and organs. The VSIM application supports the use of automatic contouring and segmentation or a model based segmentation (MBS) library of anatomical regions may be used. The contours and segmentation can be manually adjusted prior to use by the treatment planning system.
Additionally, the user is able to identify the patient isocenter, place treatment beams, and identify beam modifiers (blocks, apertures, and MLCs). The simulation is then available for radiation treatment planning for dose calculation via the KonRad software component or other treatment planning systems. The plans are then reviewed and approved by the clinician prior to transfer to the delivery system for the actual treatment.
The KonRad software component is intended to optimize multi-leaf (MLC) positions or partial attenuation block shapes for intensity modulated external beam radiation therapy (IMRT). Once the optimization is complete, the dose distribution and dose volume histogram curves are displayed for the user to evaluate. After approval, the results are exported to the delivery equipment, linear accelerator, or record and verify system, for final verification prior to treatment delivery.
