Grid Cassettes - parallel
The fogging of X-ray images resulting from scattered radiation reduces contrast and decreases diagnostic value of the radiograms Optimal X-ray images can only be obtained with help of scattered-radiation grids.
Grid cassettes conform in all dimensions (14mm thickness) to DIN standards and can therefore be used in all common cassette holders. Parallel grids are used wherever the high focussing and centering precision demanded by foccused grids cannot be met e.g. at the beside, in the operating room or in the accident ward.
Parallel grids generally employ the "prosmatic cross-section design" in which the lamella height decreases progressively from the center towards the edges running parallel to the lamellae.
This feature is especially advantageous in the case of large film sizes and short filmfocus distances. In this way the absorption of primary radiation in the perpheral zones is largely prevented.
Parallel grids with constant lamella height are also available on request. Grid cassettes with Lysholm parallel grids which are available in all sizes, incorporate lead grids with an interposed medium of aluminium. Parallel grid cassettes can be used in the focussing range from 95 cm to infinity.
We also offer parallel grids, please state drid size and direction of the lamellae. For the 70-line grid, higher grid ratios can also be provided.

Grid Cassettes - fokussed
Focussed grids offer optimal absorption of scattered radiation with maximum passage of primary radiation.Our grid cassettes conform in all dimensions to the DIN standards and can therefore be used in all common cassette holders.
The grid is factory-mounted in the cassette and is joined with the bottom of the cassette (the tube side) across its entire surface. The aluminium plate usually interposed between the grid and the bottom of the cassette can be dispensed with, since the grid and the cassette bottom form an integral unit.
The grid in the cassette is provided with a metal cover. This form represents the ideal solutionfor protecting both sides of the grid against physical damage and is especially recommenable for use in conjunction with scattered-radiation grids.
We deliver lead-grid cassettes in all commonly used sizes al well as in any special size requested. No restriction is placed on length and width.
Grids having a length of more than 50 cm are composed of two or three pieces fitted together. do not hesitate to consult us regarding special sizes and special foci. The grid cassettes in stock incorporate the Siemens lead grid Pb 8/40/115.
This reference number indicates that this universal grid has a grid ratio of 8, a lamella density of 40 per cm, and a focal distance of 105 cm. This focal distance is suitable for use with focus-film distances of 96-150 cm. The grid is also available in any other desired focal distance. Please consult us.
