The number of CT examinations giving a relatively high patient exposure is increasing. It is therefore important to optimize the imaging conditions at these investigations. Many steps have been taken to reduce the radiation doses in CT examinations. Currently much work is related to iterative image reconstruction methods as alternative to the filtered back projection method. The aim of this

iDose4™ substantially improves image quality and lesion conspicuity and reduces noise in low-dose chest CT. Compared to RDCT, high iDose4™ levels provide equivalent image quality in LDCT, hence suggesting a potential dose reduction of almost 80%.

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 Objective image noise was significantly less using IMR than iDose4 (P < 0.0001).

Contrast-to-noise ratio significantly increased with iDose4 and IMR compared to FBP (p<0.05).
