Intended Use

AI-Rad Companion (Cardiovascular) is image processing software that provides quantitative and qualitative analysis from previously acquired Computed Tomography DICOM images to support radiologists and physicians from emergency medicine, specialty care, urgent care, and general practice in the evaluation and assessment of cardiovascular diseases. It provides the following functionality: - Segmentation and volume measurement of the heart - Quantification of the total calcium volume in the coronary arteries - Segmentation of the aorta - Measurement of maximum diameters of the aorta at typical landmarks - Threshold-based highlighting of enlarged diameters The software has been validated for non-cardiac chest CT data with filtered backprojection reconstruction from Siemens Healthineers, GE Healthcare, Philips, and Toshiba/Canon. Additionally, the calcium detection feature has been validated on non-cardiac chest CT data with iterative reconstruction from Siemens Healthineers. Only DICOM images of adult patients are considered to be valid input.

Device Story

AI-Rad Companion (Cardiovascular) is image processing software for post-processing previously acquired adult non-cardiac chest CT DICOM images. It utilizes deep learning algorithms to perform heart segmentation, coronary artery calcium volume quantification, aorta segmentation, and identification of nine anatomical landmarks for aortic diameter measurement. The software computes cross-sectional multi-planar reformats (MPRs) and applies AHA-based thresholds to categorize aortic diameters. Used in clinical settings (emergency, specialty, urgent, general practice) by radiologists and physicians, the device provides color overlays of MPR and volume-rendered images with evaluation results. These outputs assist clinicians in assessing cardiovascular disease, potentially improving diagnostic accuracy and workflow efficiency. The software is compatible with CT data from multiple vendors (Siemens, GE, Philips, Toshiba/Canon) using filtered backprojection or iterative reconstruction.

Clinical Evidence

Retrospective performance studies on non-cardiac chest CT data from multiple U.S. clinical sites. Cardiac function validation showed a logarithmic correlation coefficient of 0.96 (N=381) for total coronary calcium volume compared to the predicate. Aorta diameter measurement validation showed an average absolute error of 1.6 mm (95% CI: [1.5 mm, 1.7 mm]) across nine landmarks (N=193). Performance was consistent across vendors and slice thicknesses.

Technological Characteristics

The output segmentation mask is then used to compute of the heart volume and to define a region of interest for the coronary calcium detection algorithm. #### . Detection of coronary calcium The algorithm detects calcifications in the coronary arteries for a given non-cardiac chest CT data set (without contrast, maximum slice thickness is 3 mm). The output is the total volume of the detected coronary calcium. #### ● Segmentation of aorta The algorithm computes segmentation masks of the aorta for a given non-cardiac chest CT data set. #### . Detection of aortic landmarks Detection of anatomical landmarks (salient 3D points) is used to find out if and where a particular structure is located within the 3D image data. In particular the aortic landmarks are used to identify locations for diameter measurements. #### . Aorta diameter measurements Based on a segmented mask of the aorta and a series of detected aortic landmarks, the algorithm computes aortic landmarks according to guidelines of the American Heart Association (AHA)} provides the corresponding maximum aortic diameters. #### . Threshold-based categorization of diameter measurements The algorithm receives maximum aortic diameters at AHA-locations and applies the thresholds given in the AHA standard. The results are then labelled accordingly. 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 (Cardiovascular) demonstrated equivalent performance in comparison to the primary predicate device. A complete scientific evaluation report is provided in support of the device modifications. The performance of the AI-Rad Companion (Cardiovascular) device has been validated in retrospective performance studies on non-cardiac chest CT data from multiple clinical sites across the United States. With respect to the cardiac function, logarithmic correlation coefficient of total coronary calcium volume between subject and predicate device was 0.96 (N=381). With respect to the average absolute error in aorta diameters was 1.6 mm (95% confidence interval: [1.5 mm, 1.7 mm]) across all nine measurement locations and varied between 0.9 mm and 2.4 mm per location (N=193). Performance was consistent for all critical subgroups, such as vendors or slice thickness. ### Summary AI-Rad Companion (Cardiovascular) was tested and found to be safe and effective for intended users, uses and use environments through the design control verification process and clinical data-based software validation. The Human Factor Usability Validation showed that Human factors are addressed in 4 LF Hiratzka, GL Bakris, JA Beckman, et al., "2010 ACCF/AHA/AATS/ACR/SCA/SCA/SCA/SCA/SIR/STS/SVM guidelines for the diagnosis and management of patients with thoracic aortic disease", Circulation. 2010; 121:e266-e369 {8}------------------------------------------------ the system test according to the operator's manual and in clinical use tests with customer report and feedback form. Customer employees are adequately trained in the use of this equipment. #### VIII. General Safety and Effectiveness Concerns The device labeling contains instructions for use as well as necessary cautions and warnings to provide for safe and effective use of the device. Risk management is ensured via a system related Risk analysis, which is used to identify potential hazards. These potential hazards are controlled during development, verification and validation testing according to the Risk Management process. In order to minimize electrical, mechanical, and radiation hazards, Siemens adheres to recognized and established industry practice and standards. ### IX. Conclusions AI-Rad Companion (Cardiovascular) has the same intended use as the predicate devices. The indication for use has been modified to include a more succinct summary of device specific performance but is still within the scope of the intended use and regulatory classification as the predicate devices. The fundamental technological characteristics such as image visualization and image manipulation are the same as the predicate device. The result of all testing conducted was found acceptable to support the claim of substantial equivalence. The predicate devices were cleared based on non-clinical supportive information including bench testing and software validations. The results of these tests demonstrate that the predicate devices are adequate for the intended use. The comparison of technological characteristics, non-clinical performance data, and software validation demonstrates that the subject device is as safe and effective when compared to the predicate device that is currently marketed for the same intended use. For the subject device, AI-Rad Companion (Cardiovascular), Siemens used the same testing with the same workflows as used to clear the predicate device to demonstrate safety and performance of the technical workflow. Clinical applicability was demonstrated via software-data based validations that were derived in the same intended environment as the predicate devices. Since both devices were tested using the same methods, Siemens believes that the data generated from the AI-Rad Companion (Cardiovascular) software testing supports a finding of substantial equivalence
