Intended Use

syngo.CT Dual Energy is designed to operate with CT images which have been acquired with Siemens Dual Source scanners. The various materials of an anatomical region of interest have different attenuation coefficients, which depend on the used energy. Depending on the region of interest, contrast agents may be used. These differences provide information on the chemical composition of the scanned body materials. syngo.CT Dual Energy combines images acquired with low and high energy spectra to visualize this information. The functionality of the syngo.CT Dual Energy applications is as follows: - Monoenergetic - Brain Hemorrhage - Gout Evaluation - Lung Vessels - Heart PBV - Bone Removal - Lung Perfusion - Liver VNC - Monoenergetic Plus - Virtual Unenhanced - Bone Marrow - 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 Description

Dual energy offers functions for qualitative and quantitative evaluations. Dual energy CT can be used to improve the visualization of the chemical composition of various energy dependent materials in the human body when compared to single energy CT. Depending on the organ of interest, the user can select and modify different application classes or parameters and algorithms. syngo.CT Dual Energy Software Package is a post processing application package consisting of several post processing application classes that can be used to improve visualization of various energy dependent materials in the human body. syngo.CT Dual Energy is a post processing software package designed to operate on the most recent version syngo via client server platform, which supports preprocessing and loading of datasets by syngo.via depending on configurable rules. Similar to the predicate device (K083524, clearance date April 01, 2009), syngo.CT Dual Energy allows the evaluation of CT data acquired via spiral or sequence scans at two sufficiently different energy spectra (for example 80 kV and 140 kV) achieved with dual source CT scanners.

AI/ML (Artificial Intelligence / Machine Learning)

No
The summary describes post-processing software that uses dual-energy CT data and algorithms to differentiate materials based on their attenuation properties. It does not mention any AI or ML techniques being used for this processing or analysis.

Therapeutic

No
The device is a post-processing software package that processes CT images for diagnostic purposes (e.g., visualizing chemical composition, differentiating kidney stones), but it does not directly treat or cure any medical condition.

Diagnostic

Yes

The device aids in visualization and evaluation of different materials in the human body, providing information on chemical composition and supporting differentiation (e.g., between uric acid and non-uric acid kidney stones), which are crucial steps in reaching a diagnosis. The text explicitly states that for kidney stones, it 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" and that "Only a well-trained radiologist can make the final diagnosis under consideration of all available information." This indicates its role in the diagnostic process.

SaMD (Software as a Medical Device)

Yes

The device is described as a "post processing software package" that operates on a client-server platform and processes CT images. While it relies on images from a hardware device (CT scanner), the device itself is solely the software for post-processing and visualization.

IVD (In Vitro Diagnostic)

Based on the provided text, this device is not an IVD (In Vitro Diagnostic).

Here's why:

IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to obtain information for diagnostic purposes.
Device Function: The description clearly states that syngo.CT Dual Energy is a post-processing software package that operates on CT images acquired from a scanner. It analyzes and visualizes information already obtained from the body through imaging, rather than analyzing biological specimens.
Input: The input is CT image data, not biological samples.
Output: The output is processed and visualized image data, not results from laboratory tests on specimens.

While the device provides information that can be used for diagnostic purposes (e.g., differentiating kidney stone composition), it does so by processing medical images, not by analyzing biological samples in vitro.
