Intended Use

The MR Cardiac Function Analysis software option for use with Ziostation is intended for noninvasive post-processing of DICOM compliant cardiac MR images to semi-automatically calculate and display various functional parameters, such as left ventricular ejection fraction, end diastolic volume, end systolic volume, stroke volume, cardiac output, cardiac index, wall thickness, wall thickness ratio and regional wall motion display. These measurements can be used to assist the clinician in a cardiac evaluation.

Device Story

Software add-on for Ziostation image management system; processes ECG-gated cardiac MR images. Inputs: multi-phase DICOM cardiac MR data. Operation: semi-automatically extracts left ventricular parameters including ejection fraction, volumes (end diastolic/systolic, stroke), cardiac output/index, wall thickness/motion, and volume curves. Output: quantitative functional metrics and regional wall motion displays. Used in clinical settings by physicians/clinicians to assist in cardiac evaluation. Benefits: provides objective functional measurements to support clinical decision-making regarding cardiac pathology.

Clinical Evidence

No clinical data. Bench testing only; software integration testing, verification, and validation performed.

Technological Characteristics

Software-only device; no physical materials. Operates as an add-on to the Ziostation image management system. Processes DICOM-compliant cardiac MR images. Connectivity via Ziostation platform.

Indications for Use

Indicated for clinicians requiring noninvasive post-processing of DICOM-compliant cardiac MR images to calculate and display left ventricular functional parameters and wall motion for cardiac evaluation.

Regulatory Classification

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.

Special Controls

*Classification.* Class II (special controls; voluntary standards—Digital Imaging and Communications in Medicine (DICOM) Std., Joint Photographic Experts Group (JPEG) Std., Society of Motion Picture and Television Engineers (SMPTE) Test Pattern).

#### Device Description

MR Cardiac Function Analysis is an add-on software package designed to be used with the basic Ziostation image management system to further aid clinicians in their analysis of anatomy and pathology. Universal functions such as data retrieval, storage, management, querying and listing, and output are handled by the basic Ziostation software. The additional capabilities provided by this new device are:

MR Cardiac Function Analysis software post-processes ECG-gated cardiac MR images and extracts the following left ventricular parameters from multi-phase data.

- · Left ventricular ejection fraction
- End diastolic volume
- End systolic volume
- Stroke volume
- Cardiac output
- Cardiac Index
- Wall thickness
- Wall thickness ratio
- Wall movement
- Volume Curve
- Peak Ejection Rate
- Peak Filling Rate

#### Materials

The MR Cardiac Function Analysis tool consists entirely of software. No materials are contained in this product.

#### Testing Summary

The MR Cardiac Function Analysis software package will successfully complete integration testing/verification testing prior to Beta validation. Software Beta testing/validation will be successfully completed prior to release. In addition, potential hazards have been addressed by the Ziosoft Risk Management process.

#### Summary of Substantial Equivalence

MR Cardiac Function Analysis is substantially equivalent in intended use and function to the predicate device and other devices already marketed in the US.
