An investigation of iterative reconstruction method iDOSE4
Attenueringskorrektion - CT - Yumpu
The iterative reconstruction technique's advanced algorithms provide up to 57 percent improvement in iDose 4 allows radiologists to personalize image quality based on each patient’s needs. This advanced iterative reconstruction technique provides up to 57 percent improvement in spatial resolution at low dose, and the majority of iDose 4 reference protocols are reconstructed in 60 seconds or less. 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. The end result is an image that looks more like traditional FBP. For example, compared to first-generation IR software, which had a 30 percent shift in the noise frequency spectrum, Philips’ current iDose4 AIM only has an 8-10 percent shift. “That is a remarkable difference in the visual appearance of the image,” Mendel explained. Philips provides two leading technologies that can improve image quality. iDose4* improves image quality* through artifact prevention and increased spatial resolution at low dose.
For thin-slice images, higher performance is achieved across different nodule sizes with reconstruction method “iDose4-STD”. For 1-mm thickness images, iDose4-STD and FBP-STD shows a better result in both sensitivity and precision metrics. As for 2-mm thickness images, iDose-YA and FBP-YA gain a better performance. The results of this phantom study demonstrated that high stability and flexibility of deep learning model can be used in daily clinical and screening practice.

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.

The sharper filter (C) increases the resolution.

Overall, “iDose4-YA” is suggested to achieve the best balanced results for both solid and GGO nodules. The results suggest that reconstruction methods “iDose4-STD” and “iDose4-YA” can be used for thin-slice and thick-slice, respectively, for different nodule types and sizes. 2. Methods2.1.
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. 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. The end result is an image that looks more like traditional FBP.
