    • Analysis of image quality and effective dose in adult chest phantom radiography with high BMI. 

      Sanderud, Audun; Aymon, Emmanuel; Burke, Andrea M.; Dijkstra, Susanne; Fosskaug, Julie; Silva, Andreia; Soares, Flavio Augusto (OPTIMAX 2017: Radiation dose, image quality optimisation, the use of new technology in medical imaging;, Chapter; Peer reviewed, 2018)
      Aim: To investigate the impact of different kVp and mAs values on effective dose and image quality using a chest phantom that simulates a normal sized and an obese patient. Methods and materials: A chest phantom with ...

    • Experimental article Maintaining image quality for paediatric chest CTs while lowering dose: FBP versus SAFIRE 

      Borge, Synnøve Devik; Campbell, Nina; Gomes, Ana; Raszkowski, Aysha Malgorzata; Rook, Jan Willem; Sanderud, Audun; Vallinga, Anique; Vouillamoz, Audrey; Buissink, Carst (Peer reviewed; Chapter, 2015)
      Objectives: Children have a greater risk from radiation, per unit dose, due to increased radiosensitivity and longer life expectancies. It is of paramount importance to reduce the radiation dose received by children. This ...

    • The impact of pitch values on image quality and radiation dose in an abdominal adult phantom using CT 

      Lança, Luis; Barros, Pietro; Løvlien, Ine M.; Derech, Rodrigo D’Agostini; Higgins, Daniel; Kleiker, Marjolein; McNally, Kevin; Thevenaz, Manon; Hogg, Peter; Liardet, Sebastien (Chapter; Peer reviewed, 2017)
      Purpose: To identify the impact of different pitch values on image quality and effective radiation dose for axial and coronal plane in abdominal adult CT. Methods and materials: Three scans were conducted on an abdominal ...

    • Impact of the anode heel effect on image quality and effective dose for AP pelvis: a pilot study 

      Buissink, Carst; Bowdler, Matt; Abdullah, A; Al-Murshedi, S; Custódio, S; Huhn, Andrea; Jorge, Jose; Ali, Mohammed; Peters, Annastagia Lily; Robin, Rey Yohan; Urdahl, Therese Kristin; Hogg, Peter (Chapter; Peer reviewed, 2017)
      Purpose: Using phantoms, this pilot study aims to outline a method and generate initial data to determine whether the anode heel effect has an impact on image quality and the effective dose. Methods and Materials: A ...
