X-Ray Parameters

While taking the initial frontal and lateral x-rays of the patient and fitted frame, some measurements should be made and recorded here. The software will then generate matching views of the frame with a coordinate grid, for use in determining the deformity parameters. Note that this may take some time.

If you enter a frame identifier for which you have previously defined x-ray parameters, and leave the data fields empty, then the saved data will be used and can be edited if required. Enter example-frame for example definitions.

Frame identifier

The distance from the x-ray source to the film cartridge defines the image projection. Numbers identifying the point on each ring nearest to the x-ray source define the frame orientation. The fixing holes provide a convenient scale; for example, if a point midway between hole 11 and hole 12 is nearest the x-ray source, enter 11.5. The software assumes that both rings are in contact with the film cartridge, and that the x-ray target point is the middle of the line joining these nearest points.
