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 …

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 …

Experimental article – Reducing effective dose to a paediatric phantom by using different combinations of kVp, mAs and additional filtration whilst maintaining image quality

Huizinga, Elsbeth; Schaake, Wouter (Healthy Ageing, Allied Health Care And Nursing); Visser, Ruurd; Bloomfield, Charlotte; Boavida, Filipa; Chabloz, Diane; Crausaz, Emilie; Hustveit, Hanne; Knight, Heidi; Pereira, Anna; Harsaker, Vanja

Purpose: To determine whether using different combinations of kVp and mAs with additional filtration can reduce the effective dose to a paediatric phantom whilst maintaining diagnostic image quality. Methods: 27 images of a paediatric AP pelvis phantom were acquired with different kVp, mAs and additional …
