Mobile chest imaging of neonates in incubators: Optimising DR and CR acquisitions

Introduction Neonates are a particularly vulnerable patient group with complex medical needs requiring frequent radiographic examinations. This study aims to compare computed radiography (CR) and direct digital (DDR) portable imaging systems used acquire chest x-rays for neonates within incubators. Methods An anthropomorphic neonatal phantom was imaged under controlled conditions using one machine but captured both CR DDR technology. Other variables explored were: image receptor position (direct incubator tray), tube current kV. All other parameters were kept consistent. Contrast-to-noise ratio (CNR) measured ImageJ software dose-area-product (DAP) recorded. Optimisation score calculated by dividing CNR the DAP each acquisition. Results The images highest those acquired exposures lowest placed tray. is also supported optimisation scores which demonstrated produced optimal combination regards radiation dose. had mean increase of 50.3% when comparing respectively. evident in-tray acquisitions, increasing 43.5%. A 20.4% seen in tray direct. Conclusion CNR, reducing DDR. However, still better quality compared Implications practice Where possible, should be system choice examinations on owing its superior at lower
