B-scan

A USG B-scan confirms diagnosis in the presence of a cataract.

A cross-sectional tomograph (B-scan) may be achieved by laterally combining a series of these axial depth scans (A-scan).

The doctor may also perform physical and lab examinations, such as an X-ray, an EKG, a slit lamp test, an ultrasound B-scan, or an A-scan.
