## 7.0 Device Description
RTHawk is a software system designed from the ground up to provide a platform for efficient real-time MRI data acquisition, data transfer, image reconstruction, and interactive scan control and display of static and dynamic MR imaging data.
RTHawk is an accessory to clinical 1.5T and 3.0T MR systems, operating 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, color monitor, keyboard and mouse. It is designed to operate alongside, and in parallel with, the existing MR console with no hardware modifications required to the MR system or console. This RTHawk Workstation is sourced by the Customer in conformance with HeartVista-provided specifications, and verified prior to installation.
A private ethernet network connects the RTHawk workstation to the MR scanner computer. When not in use, the RTHawk workstation may be detached from the MR scanner with no detrimental, residual impact upon MR scanner function, operation, or throughput.
The RTHawk application is written to run on top of the Linux operating system, much like application software for word processing, accounting, graphics, etc. Additional software is installed on the MR scanner computer, for receiving communications and control commands from RTHawk, and for directing MRI raw data to RTHawk for image reconstruction, display and processing.
RTHawk is an easy-to-use, yet fully functional, MR Operating System environment. The RTHawk operating system has been designed to provide a platform for the real-time acquisition, control, reconstruction, display, and storage of high-quality static and dynamic MRI images and data.
Data is continuously acquired and displayed. By user interaction or data feedback, fundamental scan parameters can be modified. Real-time and high-resolution image acquisition methods are used throughout RTHawk for scan plane localization, for tracking of patient motion, for detection
{5}------------------------------------------------
Image /page/5/Picture/0 description: The image shows the word "HEARTVISTA" in a stylized, futuristic font. The letters are black, except for a small, cyan-colored dot above the "i". The font is bold and angular, giving the word a modern and technological feel.
of transient events, for on-the-fly, sub-second latency adjustment of image acquisition parameters (e.g., scan plane, flip angle, field-of-view, etc.) and for image visualization.
Conventional MR scanners queue an entire scan ahead of time and provide for little or no modification to a scan already in progress. Conversely, the RTHawk software prepares scan waveforms just as they are needed. RTHawk's efficient management of pulse sequence waveforms and instructions for modifying those pulse sequence waveforms uses the entire scanning interval for preparation of the next sequence. Scan parameters may be manipulated in real time, while providing all checks necessary to assure patient safety. Additional features are provided to automate and facilitate the set of tasks performed during a typical cardiac exam.
RTHawk makes extensive use of spiral image acquisition techniques to maximize scan efficiency. While conventional scans acquire data line-by-line in a Cartesian grid, RTHawk collects data more efficiently in a spiral pattern. Spiral-pattern raw data must be reformatted for correct reconstruction and display, requiring additional computing resources and image correction procedures to reduce image artifacts and distortions, ensuring high-quality reconstructed images.
RTHawk implements the conventional MRI concept of anatomy- and indication-specific Protocols (e.g., ischemia evaluation, valvular evaluation, tissue characterization, etc.). Protocols are pre-set by HeartVista, but new protocols can be created and modified by the end user.
RTHawk Apps (Applications) are composed 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 (traditional) 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
- . Scan automation tools including automatic push-button localization of standard cardiac views, automatic determination of inversion time, automatic detection of artifacts, and automated myocardial segmentation
- . High spatial resolution imaging, including single breath-hold, multi-slice high-resolution GRE app offering near total heart coverage

The font is modern and geometric, with sharp angles and clean lines, giving the word a futuristic appearance. The overall design is simple yet eye-catching, with the cyan dot adding a pop of color.
- Free-breathing, multi-slice SSFP and GRE apps that rapidly acquire high-quality images - 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 imaging.
- Continuous flow quantification
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.
