If the OsteoGram can analyze one x-ray exposure then why the need for two exposures?
For Quality Assurance (QA) purposes the technology of the OsteoGram was developed for two exposures. This QA process consists of two stages. The first QA stage serves in verifying x-ray equipment. The second QA stage (when the first complies) serves in verifying the consistency of results between the two exposures for each finger. However, the OsteoGram can adequately analyze one x-ray exposure, which is an option that can be seen upon choosing a “New Test”. This option has been made available for rare cases where one exposure (out of two) is not suitable for analysis and an assessment is still needed. To obtain the best results, the OsteoGram must always be used with two valid exposures.
