The validity and reliability of the exposure index as a metric for estimating the radiation dose to the patient

Erenstein, H G; Browne, D; Curtin, S; Dwyer, R S; Higgins, R N; Pires Jorge, J A; Sauty, M; de Vries, G; England, A; Menzinga, Jacob; Hommel, S.F.

INTRODUCTION: With the introduction of digital radiography, the feedback between image quality and over-exposure has been partly lost which in some cases has led to a steady increase in dose. Over the years the introduction of exposure index (EI) has been used to resolve this phenomenon referred to as …

Inspiring radiographers to engage in research

Hogg, P; Alrehily, F; Sá Dos Reis, C; Buissink, C; Erenstein, H; Voet, Marcel

The value which research brings to health and wellbeing is unquestioned. Without it, progress in diagnosis, treatment and care would probably cease and the service offered to patients and clients would deteriorate. Engaging student radiographers, and radiographers who are early in their careers, with …

OPTIMAX

Thom Roding (Lid Lectoraat)

This year, OPTIMAX was warmly welcomed by University College Dublin. For the sixth time students and teachers from Europe, South Africa, South America and Canada have come together enthusiastically to do research in the Radiography domain. As in previous years, there were several research groups consisting …

Research article – A comparison of Sinogram Affirmed Iterative Reconstruction and filtered back projection on image quality and dose reduction in paediatric head CT: a phantom study

Bakker, Astrid; de Lange, René; Ahmed, Abdulfatah; Garcia, André; Tomkinson, David; Salamin, Julie; Buyvidovich, Sergey A.; Sohrabi, Tina; Dominguez, Alexandre; Campeanu, Cosmin

Background: Computed tomography (CT) is one of the most used modalities for diagnostics in paediatric populations, which is a concern as it also delivers a high patient dose. Research has focused on developing computer algorithms that provide better image quality at lower dose. The iterative reconstruction …

Review article – The impact of Sinogram-Affirmed Iterative Reconstruction on patient dose and image quality compared to filtered back projection: a narrative review

Plasman, Paul; Bakker, Astrid; de Lange, René; Ahmed, Abdulfatah; Garcia, André; Tomkinson, David; Salamin, Julie; Buyvidovich, Sergey A.; Dominguez, Alexandre; Campeanu, Cosmin; Sohrabi, Tina

Objective: Summarize all relevant findings in published literature regarding the potential dose reduction related to image quality using Sinogram-Affirmed Iterative Reconstruction (SAFIRE) compared to Filtered Back Projection (FBP). Background: Computed Tomography (CT) is one of the most used radiographic …

Review article - An evaluation of SAFIRE's potential to reduce the dose received by paediatric patients undergoing CT: a narrative review

Buissink, Carst; Vallinga, Anique; Rook, Jan Willem; Sanderud, Audun; Vouillamoze, Audrey

Introduction: The purpose of this review is to gather and analyse current research publications to evaluate Sinogram-Affirmed Iterative Reconstruction (SAFIRE). The aim of this review is to investigate whether this algorithm is capable of reducing the dose delivered during CT imaging while maintaining …

Research article – Optimisation of paediatrics computed radiographyfor full spine curvature measurements using a phantom: a pilot study

de Haan, Seraphine; Reis, Cláudia; Ndlovu, Junior; Serrenho, Catarina; Akhtar, Ifrah; Garcia, José Antonio; Linde, Daniël; Thorskog, Martine; Franco, Loris; Hogg, Peter

Aim: Optimise a set of exposure factors, with the lowest effective dose, to delineate spinal curvature with the modified Cobb method in a full spine using computed radiography (CR) for a 5-year-old paediatric anthropomorphic phantom. Methods: Images were acquired by varying a set of parameters: positions …
