GE Ultrasound Feature

Lung Sweep

Imaging Technology

Lung Sweep automates the process of scanning across lung fields by capturing a continuous panoramic image as the probe moves from apex to base. Instead of the standard 12-point assessment where clinicians manually position the probe at each intercostal space, Lung Sweep acquires overlapping frames and stitches them into a single extended view. This gives emergency physicians and intensivists a complete bilateral lung assessment in a fraction of the time, with consistent image quality regardless of operator experience. The feature is particularly valuable in trauma, ICU, and emergency department settings where rapid detection of pneumothorax, pleural effusion, or consolidation drives immediate clinical decisions.

Key Benefits

Why Lung Sweep matters

Complete lung assessment in one continuous scan

Lung Sweep captures all lung zones in a single sweep rather than requiring separate acquisitions at 12 individual probe positions. This cuts bilateral lung assessment time and provides a spatial overview that static images cannot match.

Consistent image quality across the entire lung field

The system maintains uniform gain, depth, and processing settings throughout the sweep. This eliminates the image variability that occurs when manually adjusting parameters at each scanning position, particularly for less experienced operators.

Faster pneumothorax localization in trauma

The panoramic view clearly shows where lung sliding stops along the pleural line, making it faster to identify and localize a pneumothorax. In trauma and emergency settings, this accelerates the decision to decompress.

Lower barrier to entry for non-specialist operators

Emergency physicians, hospitalists, and ICU nurses performing bedside lung ultrasound benefit from the automated acquisition workflow. Lung Sweep reduces the technical skill required to obtain a diagnostic-quality bilateral lung assessment.

About Lung Sweep

Traditional lung ultrasound follows a structured multi-zone protocol, typically scanning 6 zones per hemithorax (anterior, lateral, and posterior at upper and lower positions). Each zone requires manual probe placement, image acquisition, and interpretation. Lung Sweep replaces this stepwise approach with a continuous sweep motion that the system tracks in real time. As the clinician moves the probe across the chest wall, the system captures overlapping frames at high frequency and assembles them into a single panoramic view of the lung field. This panoramic output shows the pleural line, A-lines, B-lines, and any consolidation or effusion across the entire scanned region in one image. For pneumothorax detection, the continuous view makes it easier to identify the transition point where lung sliding stops, which marks the boundary of the pneumothorax. For pleural effusion, the sweep shows the fluid collection in spatial context relative to the diaphragm and lung parenchyma. The automated image assembly reduces inter-operator variability because the system maintains consistent gain and depth settings throughout the sweep. On GE Venue systems, Lung Sweep integrates with the point-of-care workflow presets, making it accessible to clinicians who may not be ultrasound specialists.
