Modified Portable A-Scan Ultrasound Instrument from a USB B-Scan Device.
Introduction: Affordable, portable A-scan ultrasound technology is important to the pediatric or mission cataract surgeon. Some units (i.e.; Biopen) are no longer marketed and report poorly on atypically shaped eyes.
Methods: A clear plastic tube-housing was shaped to accept a USB-portable B-scan for supine immersion ultrasonography.
Results: With IRB approval and consent, 34 eye surgery subjects, aged 0.3 to 70 years, had both conventional contact A-scan compared with modified B-scan immersion measurements. The correlation between them was: A-Scan = 0.995 (B-Scan) +0.197. r2 = 0.995.
Discussion: The immersion B-Scan closely matched conventional A-Scan over a range of axial lengths from 18 to 26 mm.
Conclusions: Affordable combined B-Scan and A-Scan technology can be useful for the pediatric and mission cataract surgeon.
