# 7.0 Device Description
RTHawk is a software platform intended for the efficient real-time MRI data acquisition, data transfer, image reconstruction, and interactive scan control and display of static and dynamic MR imaging data.
As an accessory to clinical 1.5T and 3.0T MR systems, RTHawk operates alongside, and in parallel with, the MR scanner console with no permanent physical modifications to the MRI system required. RTHawk is designed to run on a stand-alone linux-based computer workstation, with color monitor, keyboard and mouse. A private ethernet network connects the workstation to the MR scanner computer. When not in use, the workstation may be disconnected from the MR scanner with no detrimental, residual impact upon MR scanner function, operation, or throughput.
RTHawk is a linux operating system-level software application that is intended to control the MR scanner, acquiring high quality, real-time MRI image data and performing post-processing. The RTHawk software includes optimized image acquisition applications, a pipelined raw data image reconstruction engine, a rich graphical user interface for interactive scan control, real-time adjustment of pulse sequence parameters, and display of reconstructed images, and drivers and protocols for communications with, and control of, the OEM MR scanner console.
RTHawk Apps (Applications) are comprised of a pulse sequence, predefined fixed and adjustable parameters, reconstruction pipeline(s), and a tailored graphical user interface containing image visualization and scan control tools. RTHawk Apps may provide real-time interactive scanning, conventional (fraditional) batch-mode scanning, accelerated scanning, or calibration functions, in which data acquired may be used to tune or optimize other Apps.
The HeartVista Cardiac Package is a collection of RTHawk APPs that enables the performance of a comprehensive cardiovascular MR (CMR) study in a clinically feasible amount of time. These APPs are designed and optimized to acquire, reconstruct, and display CMR images, with features including:
- On-the-fly, sub-second latency adjustment of image acquisition parameters (e.g., scan plane, ○ flip angle, field-of-view, etc.)
- Real-time imaging, enabling less reliance on ECG gating and artifact suppression techniques. Real-time imaging may be used for scan plane localization, instantaneous tracking of patient motion, and clinical user observation of transient events
- High spatial resolution imaging, including single breath-hold, multi-slice high-resolution GRE app offering near total heart coverage
- Free-breathing, multi-slice SSFP and GRE apps that rapidly acquire high-quality images -O potentially useful for patients who suffer from arrhythmia or who cannot hold their breath
- Multi-slice dynamic SR GRE app with one heartbeat temporal resolution for time-course O imaqing.
- Continuous flow quantification o
The conventional MRI concept of anatomy- and indication-specific Protocols is implemented within the HeartVista Cardiac Package. APPs within the HeartVista Cardiac Package are organized into basic Protocols pre-set by HeartVista. The clinical user may modify APP parameters from default values within their ranges. These modified APPs may be saved into new or existing user-created Protocols to create unique CMR-indicated protocols tailored to the user's clinical interests.
RTHawk operates compatible MR scanners within the safety parameters listed in the table below:
| Safety Parameter | Safety Level |

#### 9.0 Technological Characteristics Comparison to Predicate Device
The structure of the RTHawk software is identical to the predicate device, and is comprised of the following functional modules:
- O 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 ○ reconstruction pipeline, and a specific user interface
- 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 O via a flexible, pipelined topology
- O Scan Control responsible for the real-time network transfer of controlling orders for APPs, APPs parameters modifications, and dynamic information from the MR host in response to user or program requests
- O Sequencer creates and provides a specific set of pulse sequence waveforms to control the 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.
The predicate device was described as the "HeartVista Workstation with the RTHawk application software." With the current release of RTHawk software, the workstation is specified and validated by HeartVista, and procured by the end-user.
As with the predicate device, RTHawk Apps (Applications) are comprised of a pulse sequence, predefined fixed and adjustable parameters, reconstruction pipeline(s), and a tailored graphical user interface containing image visualization and scan control tools. RTHawk Apps provide real-time interactive, batch-mode, and accelerated scanning, as well as calibration functions, in which data acquired may be used to tune or optimize other Apps. For safety, the RTHawk software is enhanced for display of worst-cast B1 RMS that the APP can potentially reach while scanning, in addition to already-displayed worst-case SAR, dB/dt.
