Background: Lung ultrasound (LUS) is a safe and non-invasive tool that can potentially assess regional lung aeration in newborn infants and reduce the need for X-ray imaging. LUS produces images with characteristic artifacts caused by the presence of air in the lung, but it is unknown if LUS can accurately detect changes in lung air volumes after birth. This study compared LUS images with lung volume measurements from high-resolution computed tomography (CT) scans to determine if LUS can accurately provide relative measures of lung aeration.

- This study presents a new approach using a scientific-CMOS (sCMOS) detector for X-ray imaging, effectively addressing issues like dark current and read-out noise.
- The detector achieves high spatial resolution (6.71 µm) by analyzing photon interactions with visible light that is produced from X-ray-induced fluorescence.
- Additionally, it offers good energy resolution (61.2% at 17 keV) and combines well with other imaging techniques to enhance signal quality, achieving a signal-to-noise ratio of 15 with very low X-ray exposure.
