Application No. 09/710,395
collection of each of emission data and transmission data.”
Independent claim 21 recites the detector head being segmented
“into a first portion for detecting emission radiation events for
generating emission image data and a second portion for detecting
transmission radiation events and generating transmission data.”
Independent claim 22 recites a collimator for restricting
radiation received by an emission imaging region of at least one
of the detector heads only to emission radiation traveling along
a desired projections path” with “the collimator blocking the
transmission radiation from being received by the emission
imaging region and enabling transmission radiation to be received
by a transmission imaging region of the at least one detector
head.”
Since none of the applied references, nor any combination of
those references, discloses or suggests these specific
limitations, no prima facie case of obviousness has been
established.
