FastSPECT II Imager
  • Key Features:
  • 16 cameras in 2 rings of 8 with adjustable radial position
  • 5 axis robotic stage for calibration and imaging subject positioning
  • Exchangeable cylindrical imaging apertures for choice of magnification/field-of-view
  • Listmode data acquisition architecture
  • Full dynamic imaging capability for periodic and non-periodic processes
  • Gigabit data link for compute-intensive processing on mini Beowulf cluster
  • Mini Beowulf cluster installed.
what makes it fastspect
What makes it FastSPECT?
  • Enough modular cameras (24) to collect entire data set required for tomographic reconstruction without camera or imaging subject motion
  • Maximum likelihood estimation techniques via pre-computed 20-bit lookup tables
  • Full calibration of camera position response functions (MDRF’s)
  • Full calibration of imaging matrix (PSF) ie No idealized modelling

What makes the new imager FastSPECT II?

  • Enlarged camera active area with larger PMT array
  • Listmode data acquisition with no binning, compression or other information loss – all raw data available for processing
  • Dynamic imaging capability without requirement for gating - every event is timed to 30 ns
  • Improved robotic stage for more convenient and precise calibration and subject positioning
