OVERVIEW

 

Image quality first

High resolution digital imaging, with the latest probe technology.

Its high signal to noise ratio helps differentiate the finest structures at all frequencies.

Wide range of probes

Flagship ultrasound system from Quantel Medical, Aviso S offers a large choice of probe frequencies to cover a wide range of applications:

  • 10MHz -> Visualization of the entire globe
  • 20MHz -> High resolution imaging of the perpendicular wall and posterior pole
  • 25MHz -> Linear scanning probe for anterior segment visualization
  • 50MHz -> Linear UBM probe for glaucoma diagnosis

Easy to use

Examination is fast and easy using Aviso S software via touchscreen remote or the computer terminal.

Exclusive Standardized Echography

Technique for tissue characterization

Standardized echography with Aviso S provides detailed and crucial information the eye, orbit and ocular annexes including:

  • Internal reflectivity of the structures
  • Location and dimension of the structures
  • Tissue differentiation
  • Certified by Prof K. Ossoinig

B-Scan examination at 10 and 20 MHz

Management of patients with trauma, uveitis, vitreoretinal disorders and differentiation of intraocular tumors

A-Scan biometry

  • Routine use prior to cataract surgery
  • Axial length measurement (easy with
  • Auto+Save Mode) and IOL calculation with all formulas

UBM examination at 25 and 50 MHz

  • Management of anterior chamber disorders
  • Analysis and Diagnosis of glaucoma

Standardized A Scan

  • Automatic video recording of the last 40 seconds of examination to review and select the best image frame
  • High performance post-processing image tools, including complete semi-automated tools for glaucoma diagnosis: AOD 500 & 750, TIA, IT 750 & 2000, ARA 500 & 750, TISA 500 & 750, LV

Standardized A Probe

A specific parallel beam probe with the same sound intensity along length of scan with an 8 MHz narrow band receiver

Unique Technology for Standardized

S Curve

An S curve amplifier that combines adequate acoustic acuity and perfect acoustic field allowing for precise visualization of reflectivity levels

Unique Tissue Model

A unique tissue model is used to calibrate the probe, which standardizes tissues Sensitivity measurements for consistent and accurate diagnosis


Unique and Extensive Diagnosis Capabilities
