|
Virtual grid |
A processing algorithm used to reduce the effect of X-Ray scatter on image quality, similar to the use of a physical X-Ray anti-scatter grid. |
|
111641
|
Fixed grid |
A physical X-Ray anti-scatter grid that does not move during exposure. |
|
111642
|
Focused grid |
A physical X-Ray anti-scatter grid with radiation absorbing strips that are focused toward the focal spot, to eliminate grid cutoff. |
|
111643
|
Reciprocating grid |
A physical X-Ray anti-scatter grid that is designed to move during exposure, to eliminate the appearance of grid lines on the image. |
|
111644
|
Parallel grid |
A physical X-Ray anti-scatter grid with radiation absorbing strips that are parallel to each other and that is used only with long source to image distances. |
|
111645
|
Crossed grid |
A physical X-Ray anti-scatter grid with crossed radiation absorbing strips used for more complete cleanup of scatter radiation. |
|
111646
|
No grid |
No physical X-Ray anti-scatter grid was used due to low scatter conditions. |
