Subjective image quality was rated significantly higher at IMR reconstructions in comparison to iDose4 and FBP. Conspicuity of central and segmental PE significantly improved with the use of IMR. In subsegmental arteries, iDose4 was superior to IMR. Together they produce high image quality with reduced artifacts. iDose⁴ gives you control of the dial so you can personalize image quality based on your patients’ needs at low dose. Designed to seamlessly integrate into your CT department, iDose4 improves image quality* with … Using "iDose4" iterative reconstruction algorithm in adults' chest-abdomen-pelvis CT examinations: Effect on image quality in relation to patient radiation exposure iDose⁴ gives you control of the dial so you can personalize image quality based on your patients’ needs at low dose. Designed to seamlessly integrate into your CT department, iDose4 improves image quality* with the look and feel of conventional images. Images from the standard examination were reconstructed with a hybrid iterative reconstruction method (iDose4), and images from the low-dose examinations were reconstructed with both iDose4 and IMR. Image quality was evaluated subjectively by three observers, according to modified EU image quality criteria, and evaluated objectively based on the noise observed in liver images. iDose4, a hybrid IR technique, filters noise iteratively in both the projection domain and the image domain [17]. Dose reductions of up to 76% have been reported without a loss of image quality [18].

Compared to RDCT, high iDose4™ levels provide equivalent image quality in LDCT, hence suggesting a potential dose reduction of almost 80%. Contrast-to-noise ratio significantly increased with iDose4 and IMR compared to FBP (p<0.05).

Results: iDose4 decreased the noise by 15–45% compared with FBP depending on the level of iDose4. The IMR reduced the noise even further, by 60–75% compared to FBP.

Objectives The aims of this study were to compare a commercially available reconstruction algorithm (iDose4) with filtered back projection (FBP) in terms of image quality (IQ) for both retrospective electrocardiographically gated and prospective electrocardiographically triggered cardiac computed tomographic angiography (CCTA) protocols and to evaluate the achievable radiation dose reduction. Results: Compared with the FBP protocol, there was an overall 46.5% significant decrease in effective dose with the use of iDose4 protocol. Conclusion: Objective image quality was higher in iDose4 June 22, 2012 — Philips introduced the iDose4 Premium Package, which includes two technologies that can improve image quality: the iDose4 iterative reconstruction technique, and metal artifact reduction for large orthopedic implants (O-MAR).
