Digirad Corporation

Digirad Corporation will showcase its latest work-in-progress during ACC.08, the American College of Cardiology's 57th Annual Scientific Session and Exposition to be held, in Chicago. Digirad's Cardius X-ACT, a dedicated cardiac SPECT system, is expected to set a new clinical standard with X-ACT attenuation correction. The system uses the Cardius-3 XPO camera's solid state detectors with an x-ray tube. The revolutionary X-ACT approach exploits the high-count rate capabilities of solid-state detectors and takes advantage of the full 24-inch-wide triple-head detector geometry to eliminate truncation. The imaging system offers the benefits of high precision, faster speed, low dose and superb reliability. Digirad also recently released nSPEED, an advanced three-dimensional SPECT image reconstruction technique. This advanced algorithm provides clinicians with significant image quality improvement over existing 2D reconstruction techniques by producing images with better contrast and spatial resolution to help improve physicians' interpretation confidence. nSPEED rapid image-acquisition protocols have demonstrated equivalent diagnostic quality for stress and rest images in half the acquisition time of traditional 2D approaches while providing reliable function quantitation measurements from gated stress images and reliable quantitation of perfusion-defect severity on stress and rest images.
