Accuracy is essential when irradiating moving targets. Yet many traditional CT scanners cannot deliver the image quality necessary for this kind of treatment planning. During 4D acquisition, they produce either too much or too little data, which causes interpolation or motion artifacts.
Patients often breathe irregularly during the 4D acquisition, which potentially causes image artifacts.
Push the boundaries for lung/ liver imaging with DirectORGANS
Hospital Particular de Viana do Castelo, Portugal. Cinematic Volume Rendering Technique (VRT) is for visualization only. This software is not commercially available.
DirectORGANS1 (Optimized Reconstruction based contours trained by Generative Adversarial Networks) is a revolutionary OAR contouring solution. It leverages optimized and standardized reconstruction parameters to deliver input to the deep learning based contouring solution. This process runs in parallel to the reconstruction of the image for target contouring.
The result: Save time and reduce unwarranted variations with high-quality contours that approach the level of consensus-based contours.
Push the boundaries for breast imaging
Deep inspiration breath-hold (DIBH) is a widely accepted method of minimizing cardiac toxicity. Current CT simulators require a longer breath-hold (20 s)7 than is required in modern treatment techniques such as high-dose-rate therapies and fast cone beam CT.
Long breath-hold during CT simulation is uncomfortable for patients and can limit their access to tailored treatment.
Push the boundaries for head and neck imaging
TwinSpiralDual Energy1 is a new form of dual-energy acquisition that uses a Tin Filter to achieve optimal spectral separation. By reducing scan times, it is especially suitable for cases involving motion.
The result: Precise target delineation thanks to improved soft-tissue contrast.
Behind Direct i4D
Take a look behind the development of one of our latest technologies, Direct i4D1,4: The world's first 4D CT sequence that intelligently adapts to the patient's breathing in real time.
The flexible, intuitive system synchronizes data across all integrated components. It operates via one user interface and requires a single vendor service contract. This means you can spend less time managing CT simulation and more time focusing on your patients – in the comfortable and calming environment that SOMATOM go.Open Pro creates for them.

“We have steadily increased the number of 4D CT simulations we perform weekly and we are close to plan 100% of our lung cancer patients with Direct i4D1,4. It provides excellent images with barely any artifacts. It also provides superb images in the abdominal area to assess movement of liver lesions or adrenal glands. We have found it to facilitate our workflow massively.”10

The software version VA40 for the SOMATOM go.Sim and SOMATOM go.Open Pro is pending 510(k) clearance, and is not yet commercially available in all countries. Its future availability cannot be guaranteed.
As shwon by measurements with a Gammex 467 Tissue Characterization Phantom comparing standard reconstructionn 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.
