Taking the trouble out of your tracer development

The SurgVision Explorer Air* camera uses patent pending, high-fidelity Multi-Spectral Normalized Imaging (MSNI) technology, developed specifically for the visual assessment of fluorescence in tissue. MSNI uses optical detection and processing at multiple wavelengths – as relevant to the molecular probe – to produce an overlay of the color and fluorescence images at flicker-free video frame rates.

Sensitivity and linearity

  • A detection limit around 60 picomolar – only made feasible by innovative technology – making low tracer detection a reality. Apart from reducing side-effects and costs, this allows for microdosing and dose-finding trials.
  • Excellent linearity - regardless of variations in tracer dose, gain and exposure time.
  • The SurgVision Explorer Air* provides an unsurpassed dynamic range, removing the need to adjust the gain or exposure times, for example to accommodate variations in individual tracer uptake from case to case.

* All specifications are preliminary and subject to change based on additional testing.

Flexible image formats

  • Apart from industry standard image formats – and of course video files – the SurgVision Explorer Air* provides 16 bit RAW sensor data. This lets you do full image analysis with applications such as ImageJ or Matlab.
