The LightSpeed VCT CT scanner for cardiac imaging reportedly reduces a patient�s radiation exposure by up to 70 percent for diagnostic cardiac scans, while maintaining optimal image quality.
The LightSpeed VCT XT captures images of the heart and coronary arteries in as few as five heartbeats. With new SnapShot Pulse technology, which applies a process called prospective triggered gating, an automated response to a patient�s heart rate ensures that the X-ray is only on for portions of a scan, thus significantly reducing a patient�s X-ray exposure time.
