The description focuses on manual and semi-automatic image processing techniques (drawing tools, seed points, filters) and quantitative measurements, with no mention of AI or ML algorithms.
No
The device is described as an image analysis software application for assisting clinicians in the evaluation of lung lesions, providing visualization and quantitative information, but it does not directly treat or prevent a medical condition.
Yes
The device is a diagnostic device as it assists radiologists and clinicians in the evaluation of lung lesions and provides quantitative information for measurement of lesion volume and other characteristics to track changes in nodules or lesions.
Yes
The device is explicitly described as a "PC-based, stand-alone, non-invasive, image analysis software application" and a "software tool." The description focuses solely on software functionalities for image processing and analysis, with no mention of accompanying hardware components being part of the device itself.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: Lung CAR I.1 is a software application that analyzes medical images (CT scans) of the lung. It does not perform any tests on biological samples. Its purpose is to assist clinicians in evaluating lung lesions based on imaging data.
Therefore, while it is a medical device used in the diagnostic process, it falls under the category of medical imaging software rather than an in vitro diagnostic device.

Intended Use / Indications for Use
Lung CAR I.1 is a PC-based, stand-alone, non-invasive, image analysis software application for the display and visualization of 2D and 3D medical image data of the lung derived from CT scans, for the purpose of assisting radiologists and other clinicians in the evaluation of lung lesions (e.g. nodules). The software provides functionality for the user to extract the region of interest (ROI) either manually using a drawing tool, or "semi-automatically" through the user selecting either a single or double seed point followed by interactive fine-tuning the boundaries of the ROI. Lung CAR I.1 provides quantative information for measurement of lesion volume and other measured characteristics over time allowing the user to review and track any changes in the physician-indicated nodules or lesions.
Lung CAR 1.1 contains additional imaging tools which allow enhancement of specified features, and which the clinician can view simultaneously with the nonenhanced view.

Device Description
Lung CAR™ (Computer Assisted Reader) 1.1 is a software tool designed to assist radiologists and other clinicians in the evaluation of nodules and other lesions in the lug. The software allows the user to select Regions of Interest either manually or by selecting a single or double seed point, followed by semi-automatic detection of the ROI boundary. It provides 2D and 3D visualisation of nodules and other lesions, and measurement of nodule characteristics such as size and volume. The further features of Lung CAR™ 1.1 as compared to the cleared device are a series of filters, the results of which are presented in a Joint Reader filter view (enhanced and non-enhanced data viewed simultaneously). These filters are an edge enhancement filter, noise removal filters and a sphericity filter. The sphericity filter enhances structures of images with spherical elements within certain Hounsfield Unit (HU) ranges that are defined by the user. This enhancement can aid the user when looking at a highlighted area (sphere) as a potential spherical nodule.

§ 892.2050 Medical image management and processing system.
(a)
Identification. A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management. The software components may provide advanced or complex image processing functions for image manipulation, enhancement, or quantification that are intended for use in the interpretation and analysis of medical images. Advanced image manipulation functions may include image segmentation, multimodality image registration, or 3D visualization. Complex quantitative functions may include semi-automated measurements or time-series measurements.(b)

Image /page/0/Picture/0 description: The image shows a stylized eye with a white ring around the iris. The background is black, which contrasts with the white ring and the detailed texture of the iris. The iris has a lighter spot, possibly a reflection, adding depth to the image. The overall design is simple yet striking, focusing on the eye as a central element.

Comparison to Predicate Device:
As in the predicate devices, MedicLung 1.0, GE ALA and Siemens LungCare CT NEV, Lung CAR1.1 assists users in assessing CT images for the identification and evaluation of nodules and other lesions in the colon.
Test data are provided to validate the performance of the system and its substantial equivalence to the predicate devices. The functional features and the intended use of Lung CAR 1.1 are substantially equivalent to the predicate devices. The modifications to the original device did not introduce any new potential safety risks.

Image /page/2/Picture/0 description: The image shows a stylized logo featuring an eye within a partial circle. The eye is detailed with a pupil and iris, suggesting a realistic representation. The partial circle surrounds the eye, creating a 'C' shape that frames the eye. The logo has a simple, monochrome color scheme, with the eye and 'C' shape appearing in white against a black background.
Safety:
A comprehensive hazard analysis was carried out on Lung CAR 1.1, which concluded that any residual risks were as low as reasonably practicable and judged as acceptable when weighed against the intended benefits of use of the system.
Conclusion:
Lung CAR 1.1 does not raise any new potential safety risks and is equivalent in performance to existing legally marketed devices. Lung CAR 1.1 is therefore substantially equivalent with respect to safety and effectiveness to the predicate devices.
