Intended Use

syngo InSpace 4D - Software Package is a self-contained image analysis software package. This real-time interactive evaluation in space and time for CT volume data sets provides the reconstruction of two-dimensional images into a three-dimensional image format. InSpace can be used to assist the physician in the diagnosis of blood vessels on the basis of a CT Angiography dataset (CTA). For a CTA examination a contrast media (CM) is administered into the patient's blood vessels to enhance the contrast of the vessels in the CTA dataset, i.e. high values for the Hounsfield Unit (HU). The goal is to visualize the blood vessels without other interfering anatomical structures. The syngo InSpace 4D is developed to facilitate a precise diagnosis by removing bone structures from a CTA data set. It can be used in the same way for Non CTA datasets to remove bones or extract and display selected bones, e.g. for the analysis of a fracture.

Device Story

syngo InSpace 4D is a self-contained image analysis software package for CT volume data. It transforms 2D CT images into 3D formats; enables real-time interactive evaluation in space and time. Primary function involves bone removal from CTA datasets to visualize blood vessels enhanced by contrast media; also extracts/displays selected bones for fracture analysis. Used by physicians in clinical settings to facilitate precise diagnosis. Output allows visualization of vascular structures without interfering anatomy; assists clinical decision-making by providing clearer anatomical views for surgical or diagnostic planning.

Clinical Evidence

No clinical data provided; safety and effectiveness supported by hazard analysis, software development, and verification/validation testing.

Technological Characteristics

Software-based image analysis package; operates on CT volume data; utilizes Hounsfield Unit (HU) thresholding for bone removal and vessel visualization; supports 2D to 3D reconstruction; self-contained architecture.

Indications for Use

Indicated for physicians requiring assistance in skeletal and soft tissue imaging, including blood vessel diagnosis via CT Angiography (CTA) and bone structure analysis (e.g., fractures) in CT datasets.

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.

# II. SAFETY AND EFFECTIVENESS INFORMATION SUPPORTING THE SUBSTANTIAL EQUIVALENCE DETERMINATION

# 1. General Safety and Effectiveness Concerns

The device labeling contains instructions for use and any necessary cautions and warnings, to provide for safe and effective use of the device.

Risk management is ensured via a hazard analysis, which is used to identify potential hazards. These potential hazards are controlled via software development, verification and validation testing. To minimize electrical, mechanical, and radiation hazards, Siemens adheres to recognized and established industry practice and standards.

# 2. Substantial Equivalence

The syngo InSpace 4D Software Package, addressed in this pre-market notification, is substantially equivalent to the following commercially available software package:

| Manufacturer | Product | 510(k) | Clearance date |
|--------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------|---------|----------------|
| Siemens | InSpace 3D | K011447 | Aug. 03, 2001 |
| ( Remark: | The current trade name of this software package is InSpace4D. This modification<br>refers to the temporal dependence and has been separately documented.) | | |

In summary, Siemens is of the opinion that syngo InSpace 4D Software Package does not introduce any new potential safety risks and is substantially equivalent to and performs as well as the predicate software components and the predicate device.

## 3. Intended Use

The syngo InSpace 4D software package is intended to assist the physician in skeletal and soft tissue imaging in addition to the originally approved indications.
