Contact B-scan and diagnostic A-scan are most commonly used to evaluate the posterior globe and orbit. Anterior ocular structures can be evaluated with a modified immersion B-scan examination, but are most commonly evaluated with ultrasound biomicroscopy . This chapter describes the proper methods for performing A- and B-scans.


2018-05-09 · What is B-Scan Ocular Technology? B-scan technology refers to brightness scan, and can be performed directly on an anesthetized eye. For trauma cases or for children, B-scan can be performed over the eyelid with coupling jelly. With B-scan, two-dimensional sound waves are generated at 10 MHz or higher.

Nidek Echoscan US-4000. Nidek’s Echoscan US-4000 is a three-in-one unit including B-scan, biometry and pachymetry. The B-scan mode scans 400 lines over 60 degrees. There is no PC or external printer required. On B-scan ultrasonography, the hemangioma appears as an acoustically solid mass, which is almost always identical in character to the surrounding normal choroid (Fig.

B-scan ultrasonography, or B-scan, is a diagnostic test used in optometry and ophthalmology to produce a two-dimensional, cross-sectional view of the eye and the orbit. It is otherwise called brightness scan. It is commonly used to see inside the eye when media is hazy due to cataract or any corneal opacity.

2012-02-25 are represented as vertical spikes from a baseline (A-scan) in 1956. Baum and Greenwood (1958) co-developed two dimensional, brightness mode (B-scan) ultrasonography for ophthalmology in 1958.2 Most workers prefer B-scan for ocular investigations, as it facilitates orientation and permits better recognition of tissue AN A/B SCAN & UBM ULTRASOUND PLATFORM. With an installed base of more than 2500 units worldwide, AVISO is the reference in ophthalmic ultrasound imaging thanks to its excellent image quality for posterior pole and anterior segment diagnosis.
