We considered chest, abdomen, and pelvis CT examinations before the installation of an iterative reconstruction algorithm ( iDose4) Sep 27, 2019 Average image noise was significantly lower when re- constructed with MBIR than with iDOSE4 at the same low radiation doses. The two iDose4 — the latest addition to Philips'. DoseRight tools — that provides significant improvements in image quality combined with dose reduction capabilities.

In addition, the Philips iDose4 Premium Package includes two leading technologies that can improve image quality – iDose4 and metal artifact reduction for large orthopedic implants (O-MAR). iDose4 improves image quality [4] through artifact prevention and increased spatial resolution at low dose. 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.

ClariCT2 and iDose4 were also equivalent in artifact and lesion conspicuity scores. However, these two denoising techniques failed to show significant differences in artifact and lesion conspicuity compared with FBP, possibly due to heterogeneity of study population and lesions.

The results show that the detection of the solid nodules is robust to imaging parameters, and for GGO detection, reconstruction methods “iDose4-YA” and “STD-YA” achieve better performance. For thin-slice images, higher performance is achieved across different nodule sizes with reconstruction method “iDose4 … 2019-10-29 Aurumskjöld, Marie-Louise, Kristina Norrgren, and Marcus Söderberg MODEL BASED ITERATIVE RECONSTRUCTION IMR GIVES POSSIBILITY TO EVALUATE THINNER SLICE THICKNESS THAN CONVENTIONAL ITERATIVE RECONSTRUCTION iDOSE4 – A PHANTOM STUDY.

When used in combination with the advanced CT scan technologies this provides a unique approach to managing important factors in patient care – a new era in low energy, low dose and low injected contrast imaging. The results show that the detection of the solid nodules is robust to imaging parameters, and for GGO detection, reconstruction methods “iDose4-YA” and “STD-YA” achieve better performance. For thin-slice images, higher performance is achieved across different nodule sizes with reconstruction method “iDose4-STD”.

The contrast-noise ratio of both slice thicknesses increased in order from FBP to iDose4 to IMR. The spatial resolution of reconstructed images was almost identical using IMR, FBP, and iDose4.
