The examiner adds Kaplan to Hasegawa and N’Guyen for a
teaching of multiple detector heads with opposing transmission
sources for reducing scan time.
All of the claims recite, in one form or another, the
detector head having first and second regions, as discussed supra
with regard to claim 28. Independent claim 1 recites “detecting
emission radiation events...with only the first region of each
detector head” during an emission imaging phase and “detecting
transmission radiation events...with only the second region of
each detector” during a transmission phase. Independent claim 8
recites “detecting single photon emission radiation events...with
the second region of each detector head” during an emission
imaging phase and “detecting transmission radiation events...with
the first region of each detector head” during a transmission
phase. Independent claim 16 recites “detecting emission
radiation events...with the first region of each detector head”
during an emission imaging phase and “detecting transmission
radiation events...with the second region of each detector”
during a transmission phase. Independent claim 19 recites
“segment selector circuitry connected with the detectors for
selectively disabling a different portion of each detector during
