The Use of Digital Side Markers (DSMs) and Cropping in Digital Radiography

This article explores two phenomena in the general radiography environment—the increasing use of digital side markers (DSMs) by radiographers and the possibility for radiographers to “crop” radiographs post-exposure. This article offers originality by identifying the rationales of radiographers when using digital equipment. This study formed part of a larger ethnographic study undertaken in the United Kingdom (UK). Participant observation and semi-structured interviews were used. Overt participant observation identified cropping and DSM placement within the X-ray room. Semi-structured interviews later supported and/or refuted the rationale for DSMs and cropping clinically. Two themes are discussed. First, radiographers support the use of DSMs by suggesting that mistakes will happen regardless of using an ASM and/or DSM. Furthermore, it is proposed that ASMs and DSMs can be interchangeably used in practice. Second, radiographers acknowledge the use of cropping ensuring their radiographs resemble “a textbook image.” This leads to question the optimum use of collimation in the clinical environment and how it may go unnoticed. This article concludes by recognizing some challenges digital radiography currently provides. The rationale and continuing use of DSMs and cropping of radiographs by radiographers highlights alternate complexities with digital technology in the clinical environment and how we may best overcome such challenges that influence the profession. •Uncovers the rationale for cropping radiographs in the clinical environment.•Explores attitudes of digital side markers (DSM) by radiographers.•Offers original discussion and recommendations for such phenomena. Cet article explore deux phénomènes du milieu général en radiographie: l'utilisation accrue de marqueurs latéraux numériques (DSM) par les radiographes et la possibilité de « recadrer » les radiographies après l'exposition des images. Cet article examine les justifications des radiographes par rapport à leur utilisation de l’équipement numérique. Cette étude fait partie d'une plus grande étude ethnographique entreprise au Royaume-Uni (R.-U.). Les méthodes employées comprennent l'observation des participants et les entrevues semi-structurées. L'observation manifeste des participants a permis d'avoir des interactions étroites avec des radiographes tout en observant leur pratique radiographique. Vingt-deux entrevues semi-structurées, d'une durée d'environ 45 minutes chacune, ont été menées. Les ré
