Product Detail Information

X-Ray GRID




│ DESCRIPTION │


WONSOLUTION.CO offer full lines of aluminum interspaced X-ray grids of the highest and the most precise quality to the radiologist.
WONS Grids contain the purest lead available to ensure superior efficiency in removing scattered radiation.
Superior quality images are achieved through the use of aluminum inter spacers and lead strips which are precisely milled to uniformity.
Grid strips are sealed between a smooth aluminum cover and finished in enamel providing



│ THREE TYPES OF LEAD STRIP POSITIONING │


PARALLEL TYPE
In the use of a parallel grid, no matter where the tube is located, there is never a condition under which all of the strips will be aligned with the tube, since they are all vertical. Only the strips directly under the X-ray tube can be in true alignment with the primary rays. Thus there will be cut-off on the sides of the film whenever a parallel grid is used. Therefore, we generally do not make parallel grids with a ratio higher than 6:1. It is also recommended that a parallel grid not be used at any distance less than 150cm, since the lead shadows becomes smaller as the tube is moved away from grid.

FOCUSED TYPE
In a focused grid, the lead strips are tilted progressively as they move away from center. The dotted lines drawn through each of these strips converge at a point somewhere above the grid; this point is known as the grid focus. This is where the X-ray tube should be located for perfect alignment of the primary ray with each of the strips.

CRISS-CROSS TYPE
Criss-Cross
A crossed grid is actually two grids, one above the other, with the lead strips of one perpendicular to those of the other. When enclosed in a cover, these two grids become a crossed grid..

VARIOUS SIZES

Grid sizes correspond to available Film sizes. The grids are shipped one inch larger in each dimension, except for the standard Bucky size 17-1/4×18-7/8" Grid sizes are available in any inch sizes and metric size. Special size of Grids can be made by buyer's specification or drawings

VARIOUS DENSITY

WONS Grids are available In eight density types: 60 lines/inch (24 lines/cm), 70lines/inch (28 lines/cm), 85 lines/inch (34 lines/cm), 103 lines/inch (40lines/cm), I20 lines/inch (47 lines/cm), 150 lines/inch (60 lines/cm), 178lines/inch (70 lines/cm), 200 lines/inch (80 lines/cm).

VARIOUS RATIOS

WONS Grids ratio is the height of its lead strip Compared to the space between strips.
Superline grids are available with ratios ranging from 5:1 to 15:1

FOCAL RANGE
Short, medium and long...covering tube to film distance from 28" to infinity.
In the case of the 8:1 ratio grid, it has been made with a true focus of 38', and can be used satisfactorily from 34" to 44". With higher ratio grids it is considerably narrower. In the case of the 12:1 ratio grid, it would have a range of only 36" to 40".
