No
The summary describes image processing and 3D modeling from CT data, but there is no mention of AI, ML, or related concepts like training/test sets for algorithms. The algorithm validation focuses on orientation mismatch and optimal projection determination, not learning-based tasks.
No.
The device assists physicians in analyzing images and navigating tools during cardiovascular interventions by providing a 3D model and composite images; it does not directly treat or diagnose a disease or condition.
No
Explanation: CT TrueView assists physicians during interventions by providing a 3D model and composite images for navigation, and includes measurement tools. Its intended use is to support procedural guidance and visualization rather than to diagnose a condition or disease.
Yes
The device description explicitly states "CT TrueView is a software medical device". While it operates on existing hardware platforms (Allura Xper FD series X-ray System and Interventional Workspot), the device itself is described as the software component.
Based on the provided information, no, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information about a person's health. This information is used for diagnosis, monitoring, or screening.
- CT TrueView's Function: CT TrueView processes medical images (CT and X-ray) to create a 3D model and composite images for use during cardiovascular interventions. It assists physicians in navigating catheters and guide wires.
- Lack of Specimen Analysis: The device does not analyze any biological specimens taken from the patient. Its input is imaging data, not biological samples.
Therefore, CT TrueView falls under the category of medical imaging software or image processing software used for procedural guidance, not In Vitro Diagnostics.

Device Description
CT TrueView is a software medical device with the following characteristics:
The proposed CT TrueView is considered an accessory to the currently marketed Allura Xper FD series X-ray System (Philips Medical Systems Nederland B.V., K141979). It operates on the currently marketed Interventional Workspot (Philips Medical Systems Nederland B.V., K121296) software hosting platform. The proposed CT TrueView assists physicians during cardio-vascular interventions by providing a 3D model of the coronary vessel tree. The 3D model is created from a pre-acquired 3D CT dataset segmented by the user. The proposed CT TrueView supports the physician navigating a catheter or guide wire through the coronary arteries by providing a composite image that combines a 2D X-ray exposure with a CT based 3D visualization of the heart and/or coronaries. The proposed CT TrueView provides a range of viewing angles that result in an unobstructed and minimally foreshortened projection of a specific segment and/or bifurcation. The selected viewing angles are programmed automatically on the connected Allura Xper FD series X-ray system. The proposed CT TrueView includes measurement tools to estimate the length and diameter of a segment of the 3D model and to estimate the bifurcation angle of a bifurcated segment. The proposed CT TrueView provides a CTO Navigator feature that allows the user to combine a 2D X-ray image with the 3D model of the heart and/or coronaries in one composite image.

Technological At a high level, the subject and predicate device are based on the following same technological elements: characteristics:
- Both are intended to be used in combination with the currently marketed . Allura Xper FD series X-ray System (Philips Medical Systems Nederland B.V., K141979). They both have X-ray system integration, can be controlled from the table side of the Allura Xper FD series X-ray system and get input data from the aforementioned Allura Xper FD series X-ray system.
- Both use a segmentation technique to create a 3D model of the coronary ● tree.
- Both use a cardiac modeling technique to obtain a still 3D model of the heart and /or coronary arteries.
- Both can display data that indicates the lesion length and diameter present in the segment without foreshortening.
- Both allow the physician to determine an optimal projection to visualize a specific vessel segment or bifurcation.
- Both offer visualization tools that allow the physician to manipulate and view the 3D model in different ways.
The following technological differences exist between the subject and predicate device:
- CT TrueView has automatic segmentation instead of semi-automatic . segmentation. The user can correct the segmentation results.
- o CT TrueView not only uses 2D images generated by the Allura Xper FD series X-ray system, but also uses previously acquired 3D CT data.
- CT TrueView allows the physician to assess and determine the angle of ● bifurcating vessel branches.
- CT TrueView offers curved reformat and cross sections views of the 3D model.
- CT Trueview contains an optional CTO Navigator image fusion functionality that provides a static composite image that combines a 2D Xray angiographic image with the CT based 3D model of the heart and/or coronaries. This static composite reference image assists the physician in navigating the catheter or guide wire through the coronary arteries.
As these differences/additional technological characteristics are considered low risk (only providing further support to the clinicians in performing interventions) and the functionalities were verified and validated with equivalent methods, these differences do not raise new questions on safety or effectiveness.
Therefore, CT TrueView is substantially equivalent to the currently marketed predicate device Allura 3D-CA Release 1 in terms of technological characteristics.

The results of the two studies show that the algorithms provide the user with correct information required to support the clinical procedure within the scope of the intended use of CT TrueView.
All of these tests were used to support substantial equivalence of the subject device. The test results in this 510(k) premarket notification demonstrate that CT TrueView:
- complies with the aforementioned international and FDA-recognized ● consensus standards and FDA guidance document, and
- meets the acceptance criteria and is adequate for its intended use. ●
