Benefits |
|
Two-dimensional Cellular Grid |
-
Better scatter reduction
-
Contrast Improvement
Factor increases by
5% -- 15% for 2 cm to 8 cm thick
breast,
respectively
-
Superior image clarity
|
-
Easier analysis
-
More accurate
interpretation
|
|
Air-core Structure |
-
Transmission of
desired primary
radiation increases
from 72% to 90%
|
-
X-ray dose can be
reduced by 3% - 13% for 2 cm to 8 cm
thick breast, respectively
|
|
Uniform Wall Thickness |
-
Uniform primary
transmission
-
Reduced noise
|
-
Superior image clarity
-
Easier analysis
-
More accurate
interpretation
|
|
Continuously Focused Walls |
-
Eliminates variation
across the grid
|
-
More accurate
interpretation
|
|
Smooth Wall Surface |
-
Provides a highly
reflective surface
|
-
Grid can be coated
with reflective material and filled
with scintillators. The smooth wall
can act as light guide of the
optical light produced by
scintillator to the
detector
|
|
Proprietary Grid Pattern |
-
No grid shadow
-
Shorter grid travel
-
Grid motion more
tolerant of speed and distance
variation
-
No Moire patterns
|
-
Ease of
implementation by
manufacturers
-
Applicable to existing and new
systems
-
Applicable to film
screen and digital
systems
