What is the difference between a scan and B-scan?

There are two main types of ultrasound used in ophthalmologic practice currently, A-Scan and B-scan. In A-scan, or time-amplitude scan, sound waves are generated at 8 MHz and converted into spikes that correspond with tissue interface zones. In B-scan, or brightness amplitude scan, sound waves are generated at 10 MHz.

What does B-scan stand for?

B-scan Ultrasonography, often called just B-scan or Brightness scan, offers two-dimensional cross-sectional view of the eye as well as the orbit. A B-scan is used on the outside of the closed eyelid to view the eye.

How does a B-scan work?

B-scan ultrasound uses high frequency soundwaves that are transmitted from a probe/transducer into the eye. As these soundwaves strike the intraocular structures, an echo is reflected back to the probe and converted into an electrical signal. This signal is then reconstructed into a two-dimensional image on a monitor.

What is a retinal B-scan?

B scan, or Bright Scan ultrasonography is a diagnostic imaging tool utilized when the view to the back of the eye, or posterior segment is hindered. The posterior segment of the eye is the back two-thirds of the eye and consists of the vitreous, retina, optic nerve, and choroid.

What is the most commonly used technique to perform a B-scan?

The most effective method to examine the extent of the retina during a B-scan is to use the limbus-to-fornix technique. To perform this technique, the ultrasonographer should gently glide the probe from the limbus of the eye to the fornix in a sweeping motion to maximize the amount of retina visualized during the scan.

How many clock hours does a typical B-scan image show?

The transverse probe position most commonly is used. This technique demonstrates the lateral extent of the pathology and encompasses approximately 6 clock hours.

What are the advantages of B-scan?

Advantages Of The B-Scan They include: Images of the eye can be obtained from all patients. Accurate results. Painless procedure.
