A/B/S/UBM Ultrasound Platform ABSolu - Quantel medical

A/B/S/UBM Ultrasound Platform ABSolu

  • 20Mhz B probe with 5 ring annular array technology
  • Enhanced UBM imaging
  • Patented motion sensor in B probes and UBM
  • DICOM standard display


Quantel Medical has made a decisive leap forward with a new 5 ring annular technology on a 20 MHz probe. The principle is to emit alternating ultrasounds by 5 concentric transducers located in a single probe.

The images thus obtained are spectacular as the entire eye is now visible with an exceptional level of detail.


The annular 5 ring 20 MHz B probe:

  • Increases depth of field by 70%,
  • Increases lateral resolution by 27%,
  • Maintains high axial resolution.

The annular technology allows to simultaneously examine pathologies of the vitreous, the retina and the orbital part.


UBM technology makes it possible to diagnose the structures behind the iris, that other technologies cannot visualize.

Quantel Medical now offers optimised UBM technology:

  • New signal processing for enhanced resolution and penetration,
  • Linear transducer motion to optimise image quality,
  • Electromagnetic technology to increase speed acquisition and comfort of use,
  • Clearscan™ compatible: rapid and comfortable examination.


The B15, B20 and UBM probes are equipped with a position sensor that provides real-time essential information such as:

  • The position of the probe on the eye,
  • The direction of the ultrasound beam.

This helps the operator to identify the area of examination more rapidly.
