1. A portable, dual-energy radiographic x-ray imaging and bone density measuring system, comprising:
a power source selected from the group consisting of: an internal battery, an external battery, an internal AC power source, an external AC power source, an internal DC power source, and an external DC power source; an X-ray source configured to emit an X-ray beam through a filter positioning mechanism, wherein the X-ray beam comprising a first voltage and a second voltage, the first voltage being higher than the second voltage, wherein the filter positioning mechanism comprising a high energy filter, a low energy filter, and a shutter configured to block transmission of the X-ray beam; an X-ray imaging detector; a housing positioning the X-ray source at a distance from the X-ray beam imaging detector, wherein the housing is configured for positioning a bone between the X-ray source and the X-ray imaging beam detector; a system configured to activate the X-ray source and to control the position of the filter positioning mechanism and imaging data acquisition. |
