Appeal No. 97/2300
Application No. 08/282,671
independent form including all of the limitations of the base
claim and any intervening claims.
The disclosed invention relates to a computed tomography
imaging system that uses a two-dimensional array of detector
elements. A switch assembly connected to the two-dimensional
array of detector elements through row enable lines
selectively enables the detector elements in response to
control signals.
Claim 1 is the only independent claim on appeal, and it
reads as follows:
1. A computed tomography imaging system which
comprises:
a two-dimensional array of detector elements for
receiving photons emanating from an x-ray source and producing
electrical signals proportional thereto, the detector elements
being located in rows which define an in-slice direction and
the same detector elements being located in columns which
define a slice direction; a digital acquisition system having
a set of pre-amplifiers, one pre-amplifier for each column of
the array of detector elements, and each pre amplifier being
connected to receive the electrical signals produced by the
detector elements in the pre-amplifier's corresponding column
of the two-dimensional array of detector elements;
a switch assembly connected to the two-dimensional array
of detector elements through row enable lines and being
operable in response to control signals to selectively enable
the detector elements in each row to apply their electrical
signals to their corresponding pre-amplifiers; and
