Philips introducerar en ny CT-plattform som ger lika bra

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”. 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.

Arapakis I, Efstathopoulos E, Tsitsia V, Kordolaimi S, Economopoulos N, Argentos S, Ploussi A, Alexopoulou E. 4 The iDose4 advantage Web 2.0 described the evolution of the web from being data-driven to user-centric, redefining the way people connect, share, and use the Internet. 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.
