EBME Forums Forums Maintenance Technical Assistance B Scan, Ophthalmic Ultrasound Scanner

Do you know of a test tool that can verify the performance of an eye scanner. Pls share your experience.

Hi Roger,

That is an interesting question! For opthalmic A scanners, you can use a test cylinder that produces an echo at a known distance, and check that the scanner measuring 'calipers' gives the same distance reading.

For B scanners, I guess ideally you would have some sort of phantom, containing targets to check the penetration and resolution etc of the probe/scanner. These phantoms are available for abdominal/obstetric etc scanners, but I don't know if anyone makes them for opthalmic scanners.

Oh thanks Tony!

BTW is the test cylinder a standard test object available in the market. I try the Alcon test object onto another manufacturer but it doesn't seem to fall into the acceptable range of measurement.

Regards

Hi Roger,

The test cylinder I have used came from Sonomed, who manufacture Ophthalmic A and B scanners.
