The x-ray is now ready for BMD testing using the OsteoGram system OsteoGram x-ray settings: The first time you take an OsteoGram hand x-ray you may need to experiment with the settings to optimize the results. Once the optimum settings are determined, they can be reused thereafter as long as the film type or CR plate are the same. Choose x-ray settings to obtain a hand radiograph with a background Optical Density of 1.1 ± 0.2, this can be verified on a light box by: Comparing the background of your x-ray to the background of the provided sample x-ray Comparing the background of your x-ray to an optical calibration step wedge Measuring the density of the background of your x-ray using an optical densitometer
