Intended Use

The Diagnosoft, Inc. HARP 2.06 is a stand-alone software package which provides the capability to review, analyze, and report on magnetic resonance (MR) images. HARP can import images from an MR system and display them in a viewing area on the computer screen. Images can be organized and displayed by study and series and organized into three-dimensional and temporal (multi-phase) collections. Temporal sequences can be displayed in a cine mode to facilitate visualization. Tagged MR images can be imported, displayed, and analyzed. Available measurements include displacement, twist, and radial, circumferential, and principle strains. Tools are provided for display of regional motion properties of the heart. A report interface is provided. Measurement tools provide information that can be output in standardized or specialized report formats. This interface makes it possible to quickly and reliably fill out a complete clinical report of an imaging exam. The results of the measurement tools are interpreted by the physician and can be communicated to referring physicians in supporting the determination of a diagnosis.

Device Story

HARP 2.06 is a stand-alone software package for cardiac MR image analysis; imports tagged MR images from MR systems; processes images to quantify regional/global cardiac function; calculates displacement, twist, and radial/circumferential/principle strains; provides cine visualization and report generation interface. Used in clinical settings by physicians to interpret cardiac motion properties; supports clinical decision-making by providing quantitative data for diagnosis. Benefits include fast, reproducible measurement of myocardial motion and strain.

Clinical Evidence

Bench testing only. Testing demonstrated that the device fulfills prospectively defined performance criteria and meets user needs.

Technological Characteristics

Stand-alone software package; utilizes HARP (Harmonic Phase) methods for myocardial motion and strain analysis; processes tagged MR images; provides GUI for image organization, cine display, and reporting.

Indications for Use

Indicated for clinical review, analysis, and reporting of magnetic resonance (MR) images, specifically tagged MR images for the assessment of cardiac function, including displacement, twist, and strain measurements in patients undergoing cardiac MR imaging.

Regulatory Classification

Identification

A magnetic resonance diagnostic device is intended for general diagnostic use to present images which reflect the spatial distribution and/or magnetic resonance spectra which reflect frequency and distribution of nuclei exhibiting nuclear magnetic resonance. Other physical parameters derived from the images and/or spectra may also be produced. The device includes hydrogen-1 (proton) imaging, sodium-23 imaging, hydrogen-1 spectroscopy, phosphorus-31 spectroscopy, and chemical shift imaging (preserving simultaneous frequency and spatial information).

Special Controls

*Classification.* Class II (special controls). A magnetic resonance imaging disposable kit intended for use with a magnetic resonance diagnostic device only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.
