GE Ultrasound Feature

SignalMax

Imaging Technology

SignalMax is GE's signal processing technology for the Vscan Air CL handheld ultrasound. It optimizes the signal-to-noise ratio by boosting the useful acoustic return while suppressing background noise and artifacts. The result is improved image contrast and resolution from a device small enough to fit in a coat pocket. SignalMax makes the biggest difference in technically challenging scenarios: imaging patients with high BMI, scanning through dense tissue, or working at greater depths where signal attenuation degrades image quality on standard handheld devices.

Key Benefits

Why SignalMax matters

Close the image quality gap between handheld and cart-based systems

SignalMax processing extracts more diagnostic information from the Vscan Air CL's compact transducer. Clinicians get images closer to what they expect from larger systems, making the handheld viable for clinical decisions that would otherwise require a full-size ultrasound.

Improved visualization in technically difficult patients

Patients with high BMI, dense tissue, or unfavorable acoustic windows benefit most from SignalMax. The noise suppression and signal amplification help maintain image quality in scenarios where standard handheld devices produce non-diagnostic images.

Maintain resolution at deeper scanning depths

Signal attenuation increases with depth, degrading image quality in abdominal and cardiac applications. SignalMax compensates by processing the weakened deep-tissue returns more aggressively, preserving usable image detail at depths that challenge other handheld devices.

Active across all imaging modes automatically

SignalMax processing runs in B-mode, Color Doppler, PW Doppler, and M-mode. Clinicians benefit from improved signal quality regardless of the exam type, without activating a separate setting for each mode.

About SignalMax

SignalMax addresses the fundamental physics challenge of handheld ultrasound: smaller transducers with limited power produce weaker acoustic signals, which means more noise in the image compared to cart-based systems. SignalMax applies signal processing algorithms to the raw acoustic data before the image is displayed. The processing amplifies the clinically relevant signal (tissue reflections) while filtering out electronic noise, reverberation artifacts, and other interference that muddies the image. This processing improves both contrast resolution (the ability to distinguish between tissues of similar echogenicity) and spatial resolution (the sharpness of tissue boundaries). For clinicians using the Vscan Air CL in ICU, emergency, or primary care settings, SignalMax narrows the image quality gap between handheld and cart-based systems. This is particularly noticeable in abdominal imaging, where depth penetration matters, and in MSK imaging, where fine tissue detail determines diagnostic confidence. The technology works across all four imaging modes (B-mode, Color Doppler, PW Doppler, M-mode), improving visualization quality regardless of the exam type.
