Dose Iterative Reconstruction Technique Delivers Improved Image at Low Dose

An iterative reconstruction technique has been developed that gives radiologists control of the dial so they can customize image quality depending on clinical needs at low dose.

Philips Healthcare (Best, The Netherlands) announced that Philips iDose4, the latest generation of Philips iterative reconstruction technique, has nearly 500 sales. While iDose4 only began shipping in March 2011, its success confirms the need of radiologists to be able to both acquire and reconstruct images in less time, with improved image quality at low dose.

When used in combination with the advanced technologies of the iCT, Ingenuity, and Brilliance computed tomography (CT) 64 scanner families, this provides a novel approach to managing important factors in patient care--a new era in low energy, low dose, and low injected contrast imaging.

With iDose4, radiologists can customize image quality-based on each patient’s specific needs. The iterative reconstruction technique’s sophisticated algorithms provide up to 57% improvement in spatial resolution at low dose, and the majority of factory protocols are reconstructed in 60 seconds or less with iDose4.

“We’re not just talking about a scan. We’re talking about detailed pictures of the coronary arteries being obtained in three seconds noninvasively. That’s revolutionary,” said Harvey Hecht, MD, director of cardiovascular CT at Lenox Hill Hospital (New York, NY, USA).

iDose is easy to use and simple for radiologists to adopt into their existing standard of care. Designed to integrate into a CT department, iDose provides the look and feel of conventional higher-dose images without long processing times. “Philips has an ongoing commitment to expand clinical possibilities and patient care,” said Jamie Valliant, global director, CT product portfolio, for Philips Healthcare. “Nowhere is this more important than in image quality and at low dose. With iDose4, we provide a personal, holistic approach to patient care.”

iDose4 is now available globally for the iCT, Ingenuity CT and Brilliance 64 scanners. It can be integrated into a standard CT department.
