Intended Use

syngo® Dual Energy is designed to operate with Siemens Dual Source CT scanners. CT images taken at the same time, using two different kV levels, of the same anatomical region of a patient are used. Depending on the region of interest, contrast agents may be used. The differences in the energy dependence of the attenuation coefficient of the different materials provide information about the chemical composition of body materials. The images are combined to visualize and analyze information about anatomical and pathological structures. The functionality of the syngo® Dual Energy applications are as follows: Lung Nodules; Xenon (Lung Ventilation); Monoenergetic; Brain Haemorrhage; Gout Evaluation; Lung Vessels; Heart PBV; Dual Energy Bone Removal; Cartilage, Tendon, Ligament; Lung Perfusion; Liver; Hard Plaques in Vessels; Kidney Stones. Kidney Stones is designed to support the visualization of the chemical composition of kidney stones and especially the differentiation between uric acid and non-uric acid stones. For full identification of the kidney stone additional clinical information should be considered such as patient history and urine testing. Only a well-trained radiologist can make the final diagnosis under consideration of all available information. The accuracy of identification is decreased in obese patients.

Device Story

Post-processing software package for Siemens Dual Source CT scanners; inputs two series of CT images acquired at different kV levels (e.g., 80/140kV or 100/140kV). Performs material decomposition based on energy-dependent attenuation coefficients; outputs color-coded overlays on orthogonal anatomical slices (sagittal, coronal, axial). Used by radiologists in clinical settings to visualize tissue/material composition (e.g., kidney stones, gout, lung perfusion). Enables interactive adjustment of window values, color look-up tables, and masking. Assists clinicians in differentiating stone types; final diagnosis requires integration with patient history and lab results.

Clinical Evidence

Bench testing only. Phantom-based testing conducted using kidney stones of varying chemical compositions and sizes within cylindrical phantoms of varying diameters. Classification performance measured against CTDIval; performance limitations for small or multicomponent stones identified.

Technological Characteristics

Post-processing software embedded in workstation framework. Utilizes dual-energy material decomposition algorithms. DICOM compliant. Standards: IEC 60601-1-6 (usability), IEC 62304 (software lifecycle), ISO 14971 (risk management).

Indications for Use

Indicated for patients undergoing dual-source CT imaging for visualization and analysis of anatomical and pathological structures, including chemical composition of kidney stones (uric acid vs. non-uric acid). Contraindicated/limited in obese patients due to decreased accuracy.

Regulatory Classification

Identification

A computed tomography x-ray system is a diagnostic x-ray system intended to produce cross-sectional images of the body by computer reconstruction of x-ray transmission data from the same axial plane taken at different angles. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.

- Lung Nodules
Xenon (Lung Ventilation) .
- Monoenergetic .
- Brain Haemorrhage .
- Gout Evaluation .
- Luna Vessels .
- Heart PBV .
- . Dual Energy Bone Removal
- Cartilage, Tendon, Ligament .
- Lung Perfusion .
- Liver ●
- Hard Plaques in Vessels .
- Kidney Stones .

The output of the syngo® Dual Energy Software Package applications are shown within three orthogonal slices (sagittal, coronal, and axial) as overlay to anatomical grayscale information. Typically the anatomical information is built from a combination of the original dual energy scans (for example 80kV and 140kV or 100 kV and 140kV and/or by using different filters).

Window values, color look-up tables (LUTs) and masking operations for both datasets (anatomical and the material decomposition information) can be interactively defined and user modified. An additional side-by-side display of Dual Energy results is also supported, and navigation and rotation of datasets are provided.

After two series of dual energy images have been loaded from the patient browser (80kV and 140kV or 100 kV and 140kV), three orthogonal slices (sagittal, coronal, and axial) of both spectra are shown within the respective segments on the monitor in grayscale mode. The middle axial, sagittal and coronal view is used for the initial display.

The Kidney Stones application class is a post processing application that uses dual energy information to visualize the chemical composition in kidney stones. The basis for this approach is a material decomposition into tissue, uric acid, and oxalate stones. The result of material decomposition is shown as a color overlay to anatomical gray scale information.

Summary of Technical Characteristics of the Subject Device as 6. Compared with the Predicate Device:

The Kidney Stones application class is a post processing application included as part of syngo® Dual Energy Software Package. syngo® Dual Energy Software Package is a post processing application package embedded in the frame-work of a single user HW/SW architecture based on advanced workstations.

Non clinical tests were conducted for the Kidney Stones Application class during product development. Phantom based test were conducted using kidney stones of various chemical composition and sizes. The stones were put into cylindrical phantoms with varying diameters and scanned. Classification performance was measured as a function of CTDIval, and performance limitations for small or multicomponent stones are a result of the analysis.

The Risk analysis was completed and risk control implemented to mitigate identified hazards. The testing results supports that all the software specifications have met the acceptance criteria.

Testing for verification and validation of the device was found acceptable to support the claims of substantial equivalence.
