Abstract:
1. A calibration method for a radiography system comprising the steps of: providing a calibration member having a first portion comprised of x-ray attenuation material simulating x-ray attenuation properties of soft tissue and a second portion comprised of x-ray attenuation material simulating x-ray attenuation properties of bone; imaging the calibration member to generate a calibration image, the calibration image including a first and second imaged portion representing the first and second portions, respectively; determining a soft calibration measurement of the first imaged portion; determining a bone calibration measurement of the second imaged portion; providing a soft tissue calibration threshold value; providing a bone calibration threshold value; comparing the soft tissue calibration threshold value with the soft calibration measurement; comparing the bone calibration threshold value with the bone calibration measurement; and configuring the radiography system in response to the steps of comparing.
