The system can be used with any combination of these features. Enabling is handled via licensing or configuration options.

Device Story

Veolity is a software-only medical imaging platform for chest CT analysis; operates on standard PCs in standalone or client-server configurations. Inputs include digital chest CT images; processes data via automated image registration, lung segmentation, and nodule segmentation. Provides CAD findings for solid pulmonary nodules (4-30 mm) as an adjunct to initial radiologist review; calculates quantitative metrics (volume, mass, doubling time, density) and supports temporal comparison of studies. Includes a malignancy risk calculator based on the McWilliams et al. (2013) model. Radiologists use the output to identify, characterize, and track nodules; facilitates clinical decision-making in diagnostic and screening evaluations (e.g., Low Dose CT Lung Cancer Screening). Benefits include improved detection of overlooked nodules and standardized quantitative assessment of growth patterns.

Clinical Evidence

No clinical testing conducted. Substantial equivalence is supported by non-clinical bench testing, including verification and validation of software specifications and performance assessment of the CAD system. CAD performance (sensitivity and false positive rates) was compared to the primary predicate using a multi-center dataset of modern, multi-vendor CT data, demonstrating equivalent detection of solid actionable pulmonary nodules.

Technological Characteristics

Software-only medical imaging platform; runs on standard off-the-shelf PCs. Supports standalone or distributed client-server network architecture. Features automated image registration, lung/nodule segmentation, and volumetric analysis. Implements CAD for solid nodule detection (4-30 mm) and a malignancy risk calculator based on the McWilliams et al. (2013) model. Connectivity via standard network protocols for image transfer. No direct patient contact; non-sterile.

Indications for Use

Indicated for radiologists to review and analyze chest CT examinations in asymptomatic populations, specifically for the detection and characterization of solid pulmonary nodules (4-30 mm).

### 5 Device Description

Veolity is a medical imaging software platform that allows processing, review, and analysis of multi-dimensional digital images.

The system integrates within typical clinical workflow patterns through receiving and transferring medical images over a computer network. The software can be loaded on a standard off-theshelf personal computer (PC). It can operate as a stand-alone workstation or in a distributed server-client configuration across a computer network.

Veolity is intended to support the radiologist in the review and analysis of chest CT data. Automated image registration facilitates the synchronous display and navigation of current and previous CT images for follow-up comparison

The software enables the user to determine quantitative and characterizing information about nodules in the lung in a single study, or over the time course of several thoracic studies. Veolity automatically performs the measurements for segmented nodules, allowing lung nodules and measurements to be displayed. Afterwards nodule segmentation contour lines can be edited by the user manually with automatic recalculation of geometric measurements post-editing. Further, the application provides a range of interactive tools specifically designed for segmentation and volumetric analysis of findings in order to determine growth patterns and compose comparative reviews.

Veolity requires the user to identify a nodule and to determine the type of nodule in order to use the appropriate characterization tools. Additionally, the software provides an optional/licensable CAD package that analyzes the CT images to identify findings with features suggestive of solid pulmonary nodules between 4-30 mm in size. The CAD is not intended as a detection aid for either part-solid or non-solid lung nodules. The CAD is intended to be used as an adjunct, alerting the radiologist – after his or her initial reading of the scan – to regions of interest that may have been initially overlooked.

{5}------------------------------------------------

The system can be used with any combination of these features. Enabling/disabling is handled via licensing or configuration options.

From workflow perspective, incoming chest CT data is processed and prepared by the CAD server software. Ready to read data is transferred to the viewing client software. Radiologists can read and analyze the data by using different tools and compare current and prior images. Finally, findings can be reported and forwarded to long-term archives.

Veolity may be utilized in both diagnostic and screening evaluations supporting Low Dose CT Lung Cancer Screening1.

- 9. Computer-Aided Detection (CAD) of solid pulmonary nodules between 4-30 mm in size (only to be used as an adjunct, alerting the radiologist - after his or her initial reading of the scan - that mav have been initially overlooked)
## Additional Information for Risk Calculator:

The malignancy risk calculator feature in Veolity is based on the full model with spiculation developed by Brock University as described in McWilliams, et al (2013). This model allows estimating the probability that lunq nodules detected on baseline screening low-dose CT scans are malignant.

The model's performance was validated using two large population-based prospective studies: the Pan-Canadian Early Detection of Lung Cancer Study (PanCan) and the chemoprevention trials at the British Columbia Cancer Agency (BCCA), sponsored by the U.S. National Cancer Institute.

Further details can be found in McWilliams, A., Tammemagi, M.C., Mayo, J.R., Roberts, H., Liu, G., Sochrati, K., Yasufuku, K., Martel, S., Laberqe, F., Gingras, M. and Atkar-Khattra, S., (2013). Probability of cancer in pulmonary nodules detected on first screening CT. New England Journal of Medicine, 369(10), pp.910-919

{7}------------------------------------------------

### 7 Technological Characteristics Comparison

Veolity is a modified version of the previously cleared primary predicate device ImageChecker CT CAD Software System (K043617). As the new device Veolity integrates the functionality of the predicate devices and the reference device to a single device, the new device and the entirety of the predicate and reference devices are substantially equivalent in the areas of technical characteristics, general function, application, and intended use. The integrated usage was addressed and cleared for each predicate/reference device. The new device does not raise any new potential safety risks and is equivalent in performance to the existing legally marketed devices.

{8}------------------------------------------------

#### 8 Performance Data

## Non-clinical Tests Discussion:

As Veolity is the result of combining the predicate and reference devices into a single new device, the intended use changed and summarizes the intended use of all predicate devices. However, the individual functionalities of the predicate devices are used technically unchanged.

The complete functionality of subject device is covered through the Validation and Verification Plan and has been tested with respect to conformance to specifications.

In addition, the subject device's CAD system performance provides equal results in terms of sensitivity and false positive rates compared to the primary predicate device. This performance assessment is based on the panel review results that were subject in the initial submission of the predicate device.

Furthermore, the performance has been re-evaluated with a multi-center dataset with modern and multivendor CT data in terms of sensitivity and false positive rate per case. A comparable study design to the clinical study of the primary predicate device was used. The study demonstrated that the performance to detect solid actionable pulmonary nodules on modern data with subject device is equivalent to the primary predicate device.

In general, the performance of subject device is maintained using test data enriched with modern CT data.

## Clinical Tests Discussion:

N/A - No clinical testing has been conducted to demonstrate substantial equivalence.

#### 9 Conclusion

MeVis Medical Solutions has determined that its device, Veolity, is substantially equivalent to the entirety of the predicate and reference devices listed above. Resulting from the new product setup of combining the three formerly cleared separate medical devices to one medical device. the intended use changed. However, the main functionalities of the former devices remain unchanged. A comparison with the legally marketed predicate and reference devices indicates that it is substantially equivalent to the entirety of these devices, has the same (combined) intended use, principles of operation and technological characteristics and that it does not raise any new safety or efficacy concerns. Non-clinical tests demonstrate that the device is safe. effective, and is substantially equivalent to the entirety of the predicate and reference devices.
