Introduction
Computed tomography (CT) is sometimes needed during pregnancy. In this case, assessment of radiation dose received by the fetus is required. Existing methods are either cumbersome or limited in their accuracy. The aim of this study is to develop and validate computational algorithm for fetal radiation dose assessment, which could be used in clinical routine.

Introduction
Grating interferometry (GI) breast CT (GI-BCT) aims to improve breast cancer diagnosis utilizing the enhanced soft tissue visibility by combining absorption, phase and dark-field contrast and acquiring three-dimensional data of the uncompressed breast. Due to interference and scattering phenomena in an X-ray GI and the use of incoherent X-ray sources there is no established...
Introduction
The prognostic value of radiomics for non-small cell lung cancer (NSCLC) patients has been investigated for images acquired prior to treatment, but no prognostic model has been developed that includes the change of radiomic features during treatment. Therefore, the aim of this study was to investigate the potential added prognostic value of a longitudinal radiomics approach...
Background: The aim of this study was to compare the effects of switching from automated to manual acquisition parameters on image quality and radiation dose in several simulated paediatric chest computed tomography (CT) scans. The comparison was made using a CT phantom in order to obtain the lowest possible dose–length product value while maintaining an adequate image quality. The scans were...
