Improvement of CT image quality with iterative reconstruction iDose4 Aurumskjöld, Marie-Louise LU ; Norrgren, Kristina and Söderberg, Marcus LU ( 2014 ) European Congress of Radiology, 2014 Mark
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.
This study assessed the variability in radiomics features due to variations in iDose4 reconstruction level. A database of 109 normal head and neck (HN) computed tomography (CT) scans was obtained for analysis with three levels idose: ( ī'dōs ), One of the aldohexoses, isomeric with galactose; l -idose is epimeric with d -glucose. See: sugar . The iDose4 portion will present the algorithms used for iDose4 as well the different levels.
The meaning of different levels of iDose4 available will be presented and quantified. Guidelines for selection iDose4 parameters based on the imaging need will be explained. Usefulness of Ultra Low-dose (sub mSv) Chest CT Using iDose4 Iterative Reconstruction for Initial Evaluation of Sharp Fish-bone Esophageal Foreign Body, SSA05-05, 13019872, Boram Yi, The assessment of tissues depicted in medical images using radiomics has been shown to depend on a number of imageacquisition and reconstruction parameters. This study assessed the variability in radiomics features due to variations in iDose4 reconstruction level. A database of 109 normal head and neck (HN) computed tomography (CT) scans was obtained for analysis with three levels of iDose4 2013-06-11 · The Philips iDose4 iterative reconstruction software includes a metal artifact reduction feature, O-MAR, to help better reconstruct photon starved areas of CT images caused by metal implants.

While iDose4 only began shipping in March, its success validates the desire of radiologists to be able to both acquire and reconstruct images in less time, with improved image quality at low dose.
i [Host publication title missing]. European Congress of Radiology, 2014, Vienna, Österrike, 2014/03/06. One year after the installation of iDose4, the corresponding dose reduction expressed by CTDI vol, compared with the situation before the installation of iDose4, was 35%.
iDose4 (Philips Healthcare, Cleveland, OH) is a commercialized statistical IR that has a higher quality of chest–abdomen–pelvis CT images than that of FBP.
SPIE Medical Imaging, 2015, 21 Feb 2015, Orlando, United States, Abstract, 2015. 2021-04-06 The company's Brilliance iCT 256 scores highly, and there is much progress made with the iDose and iDose4 packages.
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.

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). The aim of this study is to evaluate the effect of iDose4 iterative reconstruction algorithm on radiation dose and imaging quality at chest–abdomen–pelvis (CAP) CT examinations.

iDose⁴ Results available in seconds 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]. A reconstruction speed of 18 slices per second can be reached using iDose4, which is slightly slower than Ct idose brochure 1.

The scanner provides high image quality at low dose with up to 57% improvement in spatial resolution. Personalize image quality based on your patients’ needs at low dose. Ingenuity Core128 with iDose4, reconstruction is achieved in 60 seconds or less. 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. Philips provides two leading technologies that can improve image quality. iDose4* improves image quality* through artifact prevention and increased spatial resolution at low dose.
