Atlas of Brain perfusion SPECT

• Systems should be capable of sequential image acquisition. The option to acquire multiple short studies back to back makes it possible to subsequently discard segments degraded by patient motion.

• Software should support
  

  (a) Dynamic filtering
  (b) Multiple angle (oblique) reconstructions
  (c) Surface variable attenuation corrections and
  (d) Three dimensional as well as conventional cross-sectional displays.

• Morphological and physiological image coregistration, i.e. the merging of anatomic information from CT or MRI with SPECT, is also necessary for accurate diagnosis and localization, and should be a critical element of the software. Click here to see an example.

• Three-head and annular systems should be capable of Xenon-133 SPECT imaging.
