ABSTRACT:
A projectional densitometry system performs a scan of an individual's left and right femora by using the location of one femur to estimate a starting location for scanning the opposite femur. The estimated starting location of the second femur scan is based on metric data inputted by the operator or extracted from the first femur scan. Alternatively, the densitometry system performs an initial bone-locating scan of both femora, after which it performs a second, density-measuring scan based on the metric data extracted from the initial scan. A special leg positioning device is used to properly orient both femora for scanning, obviating the need to reposition the individual after scanning the first femur.
