Is an ophthalmic ultrasound machine safe?<\/strong><\/span><\/p>\n<p>Yes, ophthalmic ultrasound is generally very safe, using non-ionizing energy, but requires prudent use by trained professionals with appropriate, eye-specific settings to avoid potential minor heating or mechanical effects, especially with prolonged exposure or advanced modes like Doppler, and it should be avoided if there&#8217;s a suspected globe rupture.<\/p>\n<\/div>\n<div class=\"auto-hide-last-sibling-br paragraph_48351 paragraph-element\">\n<p><span style=\"font-size: 12pt;\"><strong>2. Can I use the same probe for A-scan and B-scan?<\/strong><\/span><\/p>\n<p>Yes, in modern ophthalmic ultrasound systems, you often can use the same probe for both A-scan (quantitative measurements) and B-scan (imaging), especially with newer(Shanghai LINK), multi-frequency or broadband transducers designed for flexibility, though traditional setups used specialized probes for each function, with A-scans often at lower frequencies (8MHz) and B-scans at higher (10MHz+) for better resolution.<\/p>\n<\/div>\n<div class=\"auto-hide-last-sibling-br paragraph_48351 paragraph-element\">\n<p><span style=\"font-size: 12pt;\"><strong>3. How much does an eye ultrasound machine cost?<\/strong><\/span><\/p>\n<p>The eye ultrasound machine (ophthalmic ultrasound) can cost anywhere from a few hundred dollars for basic used models to over $70,000 for high-end new systems, with typical ranges for new specialized machines falling between $5,000 and $75,000, depending on brand, features (like B-scan, A-scan, or combined), portability, and whether it&#8217;s new or refurbished.<\/p>\n<\/div>\n<div class=\"auto-hide-last-sibling-br paragraph_48351 paragraph-element\">\n<p><span style=\"font-size: 12pt;\"><strong>4.
