Features |
Advantages |
Benefits |
|
High
Precision |
-
Uniformity over the
whole collimator
-
Precise geometry as
designed
|
-
No artifacts
-
No local
defects
|
|
Thin Wall
Capability |
-
Thinner walls
-
Larger opening
-
Smaller
periodicity
|
-
Thinner walls can
provide larger opening
area to allow higher
sensitivity
-
Allows small periodicity
and with high sensitivity
-
Thin walls can
match
the specifications of
digital solid-state
detectors
|
|
Wide Variety
of Materials |
-
Solid lead, gold or
copper
-
Metal powders, such as
tungsten powder
|
-
Gold has the highest
stopping power
-
Tungsten
powder
collimators offers
similar stopping power
as lead at
lower cost
-
Can be RoHS
compliant
|
|
All
Collimator Types |
-
Focused to
point (cone
beam)
-
Focused to
line (fan
beam)
-
Parallel
-
Single pinhole
or array
of pinholes
|
-
Can produce any
geometry depending on the need
|
|
Any
Collimator Hole Geometry |
-
Can be any
shape: for example, square,
circular, hexagonal,
rectangular
|
-
Can register with solid-state
detector pixels
-
Shape can be
optimized to match
detector
