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
