    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.

  2. 35. Development of semi-classical Monte Carlo techniques for the simulation of clinical grating interferometry breast CT modules

    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...

  3. 41. Longitudinal radiomics using CBCT for prognosis in non-small cell lung cancer
    Dr Janita VAN TIMMEREN (The D-Lab: Decision Support for Precision Medicine, GROW - School for Oncology and Developmental Biology, Maastricht University Medical Center, Maastricht, the Netherlands)

    Oral

    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...

  4. 29. Evaluation, comparison, and optimization of the effects of manual versus software-automated protocols on radiation dose and image quality in simulated paediatric chest computed tomography
    Dr Gianluca ARGENTIERI (Ente Ospedaliero Cantonale – IIMSI - Servizio di Radiologia del Sottoceneri - Ospedale Civico Lugano), Dr Luca BELLESI (EOC)
    22/11/2019, 10:30
    Oral

    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...
