Why temporal imaging?

Today’s PET scanners offer a very sensitive functional image for oncology and brain imaging but they suffer from:

  • poor image definition;
  • poor spatial resolution and signal/noise ratio.

Today’s PET technology is working at its physical limits:

  • A trade-off between detection efficiency and spatial resolution is limiting the localization of a 511 KeV photo-electric events to 4*4*20 mm (LSO pixels 4mm).
  • Time of Flight accuracy limited by DOI effect in the pixels and light propagation statistics to 350 ps on real size pixels (15-20 mm long).

Temporal Imaging

It's a new, patented concept (6 patents) for locating a scintillation event inside a crystal using a timing information.

It’s a new logic of decoding the signal like Anger logic or Array logic using monolithic crystals.

It works at the detector module level and dramatically improves the precision of localisation of a γ scintillation event in both space (X,Y,Z) and time (T) and Energy (E).
