The software can be used for the creation of maps and statistical evaluations providing information on lung perfusion and ventilation. Results when interpreted by a radiologist yield information that may assist in diagnosis. The results shall not be used as only source for diagnosis. LungMaps is intended for patients aged 6 years and older who require evaluation of lung perfusion and/or ventilation.

Device Story

LungMaps is a post-processing software application (OpenApp) for MRI lung analysis; operates on the syngo.via platform. Inputs: 2D time series of lung MR images. Processing: deep learning-based U-Net algorithm performs automated lung segmentation; generates perfusion-weighted and ventilation-weighted maps; calculates statistics. Output: visual maps and statistical data for radiologist review. Used in clinical settings by healthcare professionals to assist in diagnosis; not for use as the sole diagnostic source. Benefits: provides quantitative/visual assessment of lung function to support clinical decision-making.

Clinical Evidence

Dear Milind Dhamankar:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898.

The MR LungMaps application offers a range of possibilities to users, including series selection of input data, algorithm processing, data export of results, image, and result visualization, editing tools, and statistics calculation. This application is deployed as an OpenApp.

LungMaps consists of new and modified features that are similar to what is currently offered on the predicate device. The subject device includes the following modifications in comparison to the predicate device:

- New body region compared to predicate device
- Perfusion-weighted and ventilation weighted maps of the lung
- One or multiple 2D time series

# 7. Substantial Equivalence

architecture, which is the established state-of-the art method for medical image segmentation tasks.

To train the network, manual annotations were used that were all reviewed by a radiologist before being used for training, tuning, or testing. For training and testing, the Dice coefficient was selected to optimize the model. The Dice coefficient represents the primary evaluation end point. The Hausdorff distance, the average surface distance, and the volumetric difference are secondary evaluation metrics.

To train the algorithm, 1912 MR lung images were used. Training was performed on 193 subjects from 6 different data sources. Tuning was performed on 46 subjects and 382 images.

To test the algorithm, 342 images were used. On this test set, an average Dice score of 0.91 was achieved. The average and standard deviation (SD) for the Hausdorff distance is 4.1 (SD = 3.9) pixels and the average surface distance is 0.8 (SD = 0.8) pixels. The average absolute volumetric difference is 2.5 (SD = 159.5) and the relative volumetric difference is 3.2 (SD = 21.4).

The data set is a representative data set that included images acquired on 0.55T, 1.5T, and 3T MRI systems. The data set contains subjects with an age distribution from 6 to 85 years.

Any update on the network will only be implemented as a part of a new software version.

The datasets used for training were not used for validating or testing the algorithm.

Non-clinical tests such as unit test, integration testing, and system test are passed.

The system test results indicate that open defects were identified which had no impact on safety and effectiveness of LungMaps with software version VA10A.

## 10. Clinical Tests / Publications

No clinical tests were conducted for the subject device.

Clinical publications and other support documents were referenced to provide information on the use, testing and validation of the Subject Device. LungMaps produces results that are consistent with the implementation that has been evaluated in various scientific publications. The implementation in the scientific publications has been shown to correlate with standard of care techniques like DCE MRI, SPECT and 129Xe imaging and the same holds true for LungMaps.

No animal testing has been performed.

## 11. Safety and Effectiveness

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

Risk Management is ensured via a risk analysis in compliance with ISO 14971, to identify and provide mitigation of potential hazards early in the design cycle and continuously throughout the development of the product. Siemens Healthineers AG adheres to recognized and established industry standards, to minimize hazards. Furthermore, the device is intended for healthcare professionals.

| 13-79 | Software/Informatics | Medical device software - Software life cycle processes | 62304 Edition 1.1 2015-06 CONSOLIDATED VERSION | IEC |

## 12. Conclusion as to Substantial Equivalence

The extensive testing of LungMaps with software version VA10A has been successfully completed. All risk mitigations, as identified in the Risk Analysis and all relevant requirements for LungMaps with software version VA10A have been tested and verified successfully.

Verification and validation of the product within the meaning of the Quality System Regulation (21 CFR § 820.30) have been performed by trained personnel. LungMaps with software version VA10A has been found to be validated for its intended use.

Indications for Use for subject device is different compared to the predicate device; however, it uses the same hosting platform syngo.via for both the subject device and the predicate device. Both the devices are integrated into the already cleared and marketed general *syngo*.via workflow concept. LungMaps processes perfusion-weighted and ventilation weighted maps of the lung, and predicate device *syngo*.MR Neuro fMRI processes fMRI statistical maps.

The difference between the predicate device and the subject device does not impact the safety and effectiveness of the subject device.

Therefore, it is Siemens’ opinion that the safety and effectiveness of the subject device have been fully verified by objective evidence, and that the subject device performs as safely and effectively as the predicate device (K182904) and the subject device is substantially equivalent to the predicate device.
