More Information

Yes
The summary explicitly mentions "deep learning algorithm" and describes training and test sets, which are characteristic of AI/ML development.

No
The device is described as image processing software that provides analysis to support medical professionals in diagnosis and evaluation, not to directly treat or prevent disease.

Yes
The device is described as software that "supports radiologists and physicians...in the evaluation and assessment of disease of the lungs" and provides "quantitative and qualitative analysis from previously acquired Computed Tomography DICOM images." This indicates its role in assisting in the diagnosis of diseases.

Yes

The device description explicitly states "AI-Rad Companion (Pulmonary) is a software only image processing application". The entire summary focuses on the software's functionality, input data (DICOM images), and performance validation, with no mention of accompanying hardware components being part of the device itself.

Based on the provided information, this device is not an In Vitro Diagnostic (IVD).

Here's why:

  • IVDs analyze samples taken from the human body. The definition of an IVD typically involves the examination of specimens such as blood, urine, tissue, or other bodily fluids.
  • This device analyzes images of the human body. The input is explicitly stated as "Computed Tomography DICOM images," which are medical images, not biological samples.
  • The intended use is image processing and analysis. The software processes pre-acquired CT images to provide quantitative and qualitative analysis of the lungs.

While the device is a medical device that aids in diagnosis and assessment of disease, it does so by analyzing imaging data, not by performing tests on biological specimens. Therefore, it falls under the category of medical imaging software, not an In Vitro Diagnostic.

No
The provided text does not contain any explicit statement that the FDA has reviewed, approved, or cleared a PCCP for this specific device. The term "PCCP" is mentioned only in the context of a section title "Control Plan Authorized (PCCP)" with "Not Found" as its content, which does not indicate authorization.

Verification and Validation

Software Documentation for a Moderate Level of Concern software per FDA's Guidance Document "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices" issued on May 11, 2005, and "Off-The-Shelf Software Use in Medical Devices" is also included as part of this submission. The performance data demonstrates continued conformance with special controls for medical devices containing software. Non-clinical tests were conducted on the Subject Device AI-Rad Companion (Pulmonary) software version VA10 during product development.

The Risk analysis was completed, and risk control implemented to mitigate identified hazards. The testing results support that all the software specifications have met the acceptance criteria. Testing for verification and validation for the device was found acceptable to support the claims of substantial equivalence.

Bench testing in the form of Unit, Subsystem and System Integration testing were performed to evaluate the performance and functionality of the new features and software updates. All testable requirements in the Engineering Requirements Specifications keys, Subsystem Requirements Specifications keys, and the Risk Management Hazard keys have been successfully verified and traced in accordance with the Siemens product development (lifecycle) process. The software verification and regression testing have been performed successfully to meet their previously determined acceptance criteria as stated in the test plans. Electrical safety and EMC testing requirements are addressed as part of the host system (CT device or PACS system) to ensure compliance with the application IEC standards.

Siemens conforms to the cybersecurity requirementing a process of preventing unauthorized access, modifications, misuse or denial of use, or the unauthorized use of information that is stored, accessed or transferred from a medical device to an external recipient. Provided in this submission is a cybersecurity statement that considers IEC 80001-1:2010. The responsibility for compliance with IEC 80001-1-2010 is the hospital.

Clinical Data Based Software Validation

To validate the AI-Rad Companion (Pulmonary) clinical workflow, the following algorithms underwent a scientific evaluation:

  • Segmentation of lung lobes
    • The lung lobe segmentation algorithm computes segmentation masks of the five lung lobes (right upper (RUL), right middle (RML), right lower (RLL), left upper (LUL) and left lower lobe (LLL) for a given CT data set of the chest.
  • . Evaluation of the lung parenchyma

The algorithm receives a 3D CT data set and binary masks of the segmented lung lobes. It computes, the ratio of voxels below -950 HU (%LAV950) each lobe as well as for the complete lung.

For each algorithm of AI-Rad Companion the analysis is structured as follows:

  • Algorithm Description: purpose, functionality, technical description ●
  • . Data
    • Training cohort: size and properties of data used for training O
    • Description of ground truth / annotations generation O
    • Validation cohort: size and properties of data used for testing/validation o
  • Performance ●
    • Choice of performance metric O
    • Actual performance results O
    • Assessment of clinical relevance of achieved performance O
  • Related clinical research, e.g. publications (if applicable) .

The results of clinical data-based software validation for the subject device Al-Rad Companion (Pulmonary) demonstrated superior performance in comparison to the primary predicate device for segmentation. A complete scientific evaluation report is provided in support of the device modifications.

Performance of lung lobe segmentation of AI-Rad Companion.Pulmonary device has been validated in a retrospective performance study (n>4,500 CT data sets from multiple clinical sites from within and outside United States). In this study DICE coefficients, surface metrics and volume error have been computed by comparing the output of the algorithm to the manually established ground truth. The average DICE coefficients for the individual lung lobes ranged between 0.95 and 0.98 with a standard deviation (SD)
