Cardiovascular Applications

Step & Shoot Cardiac enables low dose, high quality cardiac CT imaging.  This axial prospective ECG-gated acquisition technique achieves full heart coverage within a short breath-hold.  It is ideally suited for patients where low radiation dose is needed. Arrhythmias are detected by proprietary algorithms; scanner acquisitions are adjusted accordingly.

DoseRight Cardiac

ECG Dose Modulation reduces the mA of the X-ray beam up to 80% during acquisition of non-desired phases. For example, only one phase may be required for coronary CTA, and the system will reduce the mA during the other portions of the acquisition, saving considerable dose.

Retrospective Tagging

Spiral Retrospective Tagging allows the Brilliance CT system to acquire a volume of data while the patient's ECG is recorded. The acquired data is "tagged" and reconstructed retrospectively at any desired phase of the cardiac cycle.  This phase selection is accomplished using the Philips' patented Beat-to-Beat™ Variable Delay Algorithm, which automatically finds the best phase for cardiac CT imaging.

Prospective Gating

Prospective Gating automatically triggers axial multislice scan acquisitions using patient information from the ECG monitor. This feature uses Philips patented Beat-to-Beat variable delay algorithm for accurate and reproducible calcification scoring studies.

Integrated ECG Monitor

Philips’ advanced ECG monitor is used to collect the patient's ECG signal and then transfer the signal to the scanner for gated cardiac CT imaging. This can be used to correct reconstruction artifacts caused by irregular heartbeats.

COBRA™ Reconstruction (COBRA Cardiac)

This adaptive multi-cycle reconstruction algorithm delivers the best temporal resolution possible at all times, as low as 42mseconds, in full 3-D conebeam resolution.

This is a complete cardiac evaluation package that provides simplified workflow and minimal user interaction. This high-tech cardiac analysis tool helps you visualize coronary trees, perform detailed coronary artery evaluations and analyze ventricular function. You can substantially reduce the time and complexity of a cardiac evaluation, opening the doorway to quicker, more accurate analysis for the operator and faster clinical results.

Included:

• A no-click total cardiac segmentation with complete cage removal
• Globe™ View (Globe, 3D Map and 2D Map)
• Unique “IVUS-like” view for the central cross-sectional cut
• 3D-QCA vessel measurements
• Outstanding Slab tools (including cut planes)
• New and advanced LV Functional Assessment
• Continuous identification of C-arm angles

This application uses a 3-D CT segmentation of the coronary tree to select – and visualize the best 2D C-arm projections for use in the planning for percutaneous coronary interventional (PCI) procedures in the cath lab.

Included:

• Fully integrated with Comprehensive Cardiac Analysis package
• 3D-QCA chart with stenosis calculations
• C-arm coordinates displayed
• Percent foreshortening (for best stent deployment) displayed
• Used for bifurcations, CTO’s and complex anatomy

This is a pre- and post-procedural planning tool that enables the clinician to obtain an anatomic CT view of the left atrium and the pulmonary veins before carrying out an interventional RF ablation procedure for treating arrhythmia.

May accelerate the procedural time, reduce radiation exposure and improve patient outcomes.

Provides a comprehensive set of user tools that allows quick visualization of one or multiple cardiac phases, synchronization of multiple cardiac phases with interactive slab-MIP tools for review purposes, cine mode for cardiac axes views and a simple “Area-Length” calculation of End Systolic Volume (ESV), End Diastolic Volume (EDV), Cardiac Output (CO) and Ejection Fraction (EF) for basic ventricular functional assessment.

Cardiac scoring program which provides Agatston, Volume and Mass scores. Incorporates a database of   > 5,000 asymptomatic multislice cardiac scoring patients.

CT Reporting

Provides reporting capabilities for digital transfer or paper print of clinical results from the Philips Brilliance Workspace including display of key images and results frames.
