CardioGraphe

CardioGraphe

CardioGrapheTM is the first dedicated cardiovascular CT scanner designed to provide comprehensive clinical information for diagnosis and therapy planning. CardioGraphe is optimized for imaging the entire heart and cardiovascular system with 140 mm coverage at a rotation speed of 0.24 sec per rotation.

The system uses a lower radiation dose than whole-body CT scanners. Further, the imaging based on a single heartbeat as well as the fast speed of the scan reduce contrast volumes and reduce the need for administration of beta blocker. Clinical applications from Calcium Scoring to Cardiac CTA and peripheral vascular imaging are executed easily and successfully even for patients with high or unstable heart rates and for obese patients

Key technology enablers include:

  • Unique Stereo CT®technology. Two overlapping x-ray beams rotate around the patient in parallel trajectories, achieving excellent image quality and wide z-axis coverage with no need for two detectors.
  • Focused field-of-view (FOV).CardioGraphe’s focused FOV of 250mm generates high-resolution images of the area of interest, while highly reducing radiation dose to peripheral anatomies compared to whole-body CT systems.
  • Fast gantry rotation. The 0.24 second rotation speed with partial scan mode achieves excellent cardiac imaging, with a temporal resolution of 120 msec.
  • Unique imaging chain hardware and Stereo CT®reconstruction algorithm. Unique imaging chain and reconstruction technologies generate outstanding image quality.
  • ASiR-CV. Integrated, advanced iterative reconstruction technology reduces noise and improves low-contrast detectability even at very low signal levels. This technology is designed to deliver reduced noise levels, improved low contrast detectability and may enable a reduction in dose for all clinical applications (A consultation with a physician and a physicist should be made to determine the appropriate dose to obtain diagnostic image quality for the particular clinical task).
  • Ultra-short gantry geometry. The ultra-short geometry makes efficient use of the x-ray sources.
  • Small footprint.It easy to deploy CardioGraphe, even in small rooms.

Thanks to its innovative design, CardioGraphe provides the user with breakthrough clinical applications for cardiovascular imaging:

  • One-beat, high-definition, motion-free coronary images at any heart rate, with intelligent motion correction
  • Comprehensive cardiac assessment for every patient – coronaries, structure & function
  • Temporal resolution of 120 msec in cardiac scans
  • Peripheral vascular imaging, from carotids to aorta, main pulmonary, renal and femoral arteries
  • Whole organ acquisition for 4D imaging to visualize vascular flow, organ motion or kinetic properties
  • Rapid & comprehensive TAVR planning with dedicated protocols, allowing ECG-gated and non-gated acquisitions in a single exam
