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. AVISO is used in most of the ultrasound teaching institutions across the world. 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.

AVISO is used in most of the ultrasound teaching institutions across the world. B-Scan Ultrasonography 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.

A survey of the current status of B Scan ultrasonography in ophthalmology, with examples of ultrasound photographs, is presented.

1 It currently stands as the principal diagnostic tool for a number of conditions within the eye and as a supplement to the radiologic imaging capabilities of B-scan ultrasound plays an important role in the diagnosis and management of various intraocular disorders in both clear and opaque ocular media. Although B-scan has been considered a useful tool in ophthalmology for several decades, continual developments in ultrasound technology have enhanced the ability of practitioners to detect and differentiate an array of intraocular lesions.

A-scan and B-scan are both types of ultrasound examinations performed for eye evaluation.; A detailed eye examination tells not only about the structures of the eyes but also about any underlying health conditions such as high blood pressure and diabetes.

It can be performed directly on the anesthetized eye. In cases of trauma or in children, B-scan can be performed over the eyelid with coupling jelly. Ocular ultrasound, also known as ocular echography, “echo,” or a B-scan, is a quick, non-invasive test routinely used in clinical practice to assess the structural integrity and pathology of the eye. It can provide additional information Given that ophthalmic examinations require little in the way of tissue penetration (an eye being 23.5 mm long on average) and much in the way of tissue resolution, ultrasound probes used for ophthalmic B-scan are manufactured with very high frequencies of about 10 million oscillations per second, or 10 MHz. Ocular ultrasound, also known as ocular echography, "echo," or a B-scan, is a quick, non-invasive test routinely used in clinical practice to assess the structural integrity and pathology of the eye. It can provide additional information not readily obtained by direct visualization of ocular tissues, and it is particularly useful in patients The B-Scan Plus’ and B-Scan Plus Vet's proprietary software combined with unique probe electronics make it the only portable High Definition B-Scan.

B-scan Ultrasonography, often called just B-scan or Brightness scan, offers two-dimensional cross-sectional view of the eye as 16 May 2012 Introduction; Purpose; Pioneers of Ophthalmic Ultrasound; The Original Contact B-Scan Equipment; Linear scanning technology; 'Non-Contact' It allows for a better visualization of the eye structures and the orbit hence a better Ultra-compact A/B/P ultrasound system; New 15MHz Probe generation Ultrasonography of the globe and orbit.

The B-scan mode scans 400 lines over 60 degrees. There is no PC or external printer required.

Ultrasound technology has a unique role in ophthalmology since it can contact transducer for this type of image acquisition which led to the rapid dissemination of ultrasound devices within ophthalmology clinics. The B-mode images could be used to The B-scan mode can be used to obtain radial and transverse scans to
