DirectDensity1: When Standardization Meets Personalization
In radiotherapy treatment planning, the CT image HU values must be converted to electron density. The method for conversion is sensitive to several imaging parameters, including the kV. To simplify the process, users generally calibrate at 120 kV and request that all patients be imaged at this kV. Therefore, there is no patient-optimized image quality so that accurate dose calculation is ensured—a compromise between standardization and personalization.
The new SOMATOM Confidence RT Pro uses the DirectDensity1 algorithm, which can be used to reconstruct images that can be interpreted as showing relative electron density. The use of DirectDensity1 eliminates the need for more than one calibration curve. The SOMATOM Confidence RT Pro also opens up the possibility of using CARE features to optimize imaging protocols based on each individual patient’s anatomy.
Advanced Visualization with Dual Energy
With the SOMATOM Confidence RT Pro, you can access the world of Dual Energy on your large bore CT. The images acquired with two photon spectra can be manipulated for various purposes, such as reducing artifacts or characterizing tissues in terms of electron density and effective atomic number. With FAST DE results, you can automatically generate monoenergetic datasets at the control console for a straightforward and easy-to-use workflow.
Metal Artifact Reduction with iMAR
With iMAR, Siemens Healthineers delivers metal artifact reduction capabilities on a completely new level. The algorithm combines three advanced approaches: beam hardening correction, normalized sinogram inpainting, and frequency split. iMAR can reduce metal artifacts for a wide variety of implants, including dental fillings, screws, prostheses, and pacemakers. iMAR can be used in conjunction with 4DCT acquisitions, Dual Energy acquisitions, HD FoV Pro, and SAFIRE.
syngo.via RT Image Suite
As imaging for RT advances, incorporating all available imaging information to guide treatment decisions has become a challenging undertaking. syngo.via RT Image Suite was developed for radiation oncology professionals. With its user-friendly design, RT Image Suite can aid you in transforming a range of imaging studies into insightful, actionable clinical information—even for the most complex cases. Benefit from a comprehensive solution for simulation, 3D and 4D image management and contouring, and powerful tools to support treatment decisions and response assessment—for more efficiency, more standardized output, and more integration.
Protocol Optimization with DirectDensity1
CARE kV offers an automated image quality-optimized selection of the X-ray tube voltage (kV) depending on the examination type. It is the industry’s first tool that automatically determines the appropriate kV and scan parameter settings to help deliver optimal image quality for each patient.
CARE Child enables dedicated pediatric CT imaging, including 70 kV scan modes and specific CARE Dose4D curves and protocols.
Special clinical protocols with 70 or 80 kV selection and a wide range of mAs settings. The X-ray exposure is adapted to the child’s (and small adult’s) weight and age, substantially reducing the effective patient dose while maintaining user-defined image quality.
Touch Panel Controls
Every minute spent in front of the patient versus behind a workstation, positively impacts the patient experience. This new gantry design features two Touch Panel Controls that allow therapists to spend more time at the scanner for a more personal patient experience. In addition, the location of the Touch Panels allows for convenient patient positioning, reducing the back-and-forth between the scan room and the control room.

1DirectDensity™ reconstruction is designed for use in Radiation Therapy Planning (RTP) only. DirectDensity™ reconstruction is not intended to be used for diagnostic imaging.
2As shown by measurements with a Gammex 467 Tissue Characterization Phantom comparing standard reconstruction (kernel D30) and DirectDensity™ reconstruction (kernel E30). HU value to relative electron 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.
