The iTFlow software will be utilized in situations where visualization of blood flow in a heart and its major vessels are required for a cardiac diagnosis. iTFlow allows for the viewing, post-processing, and the quantitative evaluation of cardiovascular MRI data (in DIRECTOR-compliant format)

It enables:

- The import of DICOM-compliant MR Images.

- The support of a clinical diagnosis by the quantitative analysis of the imported images.

- Quantitative measurement of the size, area, blood flow, volume and mass of the heart and adjacent vessels.

-Advanced correction options such as offset correction, background phase correction, and anti-aliasing.

-Data visualization as a graph or output as an image or numerical data.

iTFlow software will assist clinicians with proper training in cardiac treatment decision making and in providing a conclusive diagnosis for patients. It is intended to analyze cardiovascular MRI image data, that are acquired via electrocardiogram gated acquisition, gradient echo cine sequence, and phase contrast time-resolved multi-slice sequence, without any-contrast medium for MR angiography. Patient populations are not restricted.

Indications for use as stated in the FDA summary.
