More Information

Not Found

No
The document describes image acquisition, reconstruction, and display software for an MRI accessory, but does not mention AI or ML.

No
The device is described as an accessory to magnetic resonance diagnostic devices, intended to acquire and display images for diagnostic purposes, not for therapeutic intervention.

Yes
The device is described as producing images that, when interpreted by a trained physician, "provide information that may assist in the determination of a diagnosis." This indicates its role in the diagnostic process.

No

The device description explicitly states that the HeartVista Workstation consists of a "stand-alone linux-based computer workstation, color monitor, keyboard and mouse," in addition to the RTHawk software. This indicates the device includes dedicated hardware components beyond just software.

Based on the provided text, the HeartVista Workstation with the RTHawk application software is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD Definition: In Vitro Diagnostics are devices intended for use in the examination of specimens derived from the human body (such as blood, urine, or tissue) to provide information for diagnostic purposes.
  • Device Function: The HeartVista Workstation with RTHawk is an accessory to an MRI system. It acquires and processes images of the internal structures and/or functions of the entire body using magnetic resonance. It does not analyze specimens derived from the body.
  • Intended Use: The intended use is to acquire real-time and accelerated images from an MRI system to assist a trained physician in the determination of a diagnosis based on the interpretation of these images. This is a function of an imaging device, not an IVD.

Therefore, the HeartVista Workstation with the RTHawk application software falls under the category of a medical imaging device accessory, not an In Vitro Diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Clinical images were acquired using RTHowk, and were compared to images acquired on the same patient during the same imaging session using, where possible, equivalent pulse sequences and postprocessing as necessary from the predicate device. Images from both devices were evaluated and rated on the basis of diagnostic accuracy and image quality. Where no directly comparable images were available from the predicate device, RTHawk images were evaluated directly based upon radiologist expertise.

8.0 Indications for Use

The HeartVista Workstation with the RTHawk application software is an accessory to 1.5T and 3.01 whole-body magnetic resonance diagnostic devices (MRDD or MR). The HeartVista Workstation with the RTHawk application software is intended to operate alongside, and in parallel with, the existing MR console to acquire real-lime and accelerated images. The HeartVista Workstation with the RTHawk application software is indicated for Cardiovascular MR (CMR) applications.

The HeartVista Workstation with the RTHawk application software produces static and dynamic transverse, coronal, sagittal, and oblique cross-sectional images that display the internal structures and/or functions of the entire body. The images produced reflect the spatial distribution of nuclei exhibiting magnetic resonance. The magnetic resonance properties that determine image appearance are proton density, spin-lattice relaxation time (T1), spin-spin relaxation time (T2) and flow. When interpreted by a trained physician, these images provide information that may assist in the determination of a diagnosis.

The HeartVista Workstation with the RTHawk application software is intended for use as an accessory to the following OEM, MRI system, and software release versions:

  • O GE Healthcare (GEHC) Signa HDxt 1.5T, 3.0T. Software versions 15 and 16.

Technological Characteristics Comparison to Predicate Device 9.0

The RTHawk software is comprised of the following functional modules, and the predicate device's Operating System contains the same or similar functional modules:

  • C Acquisition - responsible for the transfer of MR raw data from the MR scanner to the HeartVista Workstation
  • O . Analysis contains the image post-processing tools
  • Application HeartVista APPs. Each APP is comprised of a pulse sequence, user parameters, a o reconstruction pipeline, and a specific user interface
  • O Information System - the central repository of all relevant MRI system configuration, patient, study, scan, etc., parameters associated with the current patient study
  • Reconstruction responsible for the efficient processing of raw data to generate MR images 0 via a flexible, pipelined topology
  • Scan Control responsible for the real-time network transfer of controlling orders for APPs, APPs 0 parameters modifications, and dynamic information from the MR host in response to user or program requests
  • Sequencer creates and provides a specific set of pulse sequence waveforms to control the o MR scanner
  • Storage obtains current patient and scan information, performs non-volatile local storage, O exports images and data in DICOM format, and logs events.
  • Visualization implements all aspects of the user iterface, including APP selection, controls to O modify APP parameters, image display, graphical slice prescription, and image review, save, and export.

There are subtle differences between the RTHawk's and the predicate device's intended use; the predicate device produces spectroscopic images and/or spectra, while RTHawk does not.

Both RTHawk and the predicate device offer pulse sequences with high resolution, high signal-tonoise ratio, and short scan times. HeartVista APPs are currently optimized for cardiovascular MR (CMR) applications, and the predicate device's pulse sequences and post-processing offer the same or similar imaging capabilities, including the same indications for use.

Instructions for use are included within the device labeling, and the information provided will enable the user to operate the device in a safe and effective manner.
