Designed to seamlessly integrate into your CT department, iDose4 improves image quality* with the look and feel of conventional images. iDose⁴ || Reconstruction in 60 seconds o. Results available in seconds. The majority of reference protocols reconstructed using iDose⁴ are completed in 60 seconds or less.

Together they product high image quality with reduced artifacts. Sweden stands up for open access – cancels agreement with Elsevier LUBcat LIBRIS 2021-03-04 In addition to their clinical standard-dose (SD) CT (chest: 2.9mSv; abdomen: 5.6mSv), submSv images were reconstructed with low-dose (LD) FBP, iDose4 (idose levels ID2, ID4) and IMR (i1-5 The Power of two: O-MAR* reduces artifacts caused by large orthopedic implants. iDose4* improves image quality** through noise reduction and improvements in spatial resolution.

Li, L. HUI, C. Yan-Hai; Guangzhou/CN" 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 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.

Computed Tomography (CT) numbers, noise levels,  Mar 13, 2019 Relative agreement among iDose4 reconstructions was quantified using the Spearman's rank correlation coefficient. For all ROIs besides those  following which iDose4-3 and iDose4-5 were used for target reconstruction, of U-HRCT image was lower than that of the C-HRCT image of the same iDose4  Data were reconstructed using FBP and two different IR techniques iDose4™ and IMR (Philips Healthcare) at various iteration levels.
