using an established protocol.10 (link)
The pelvis and femur were imaged at 120 kVp and 200 to 400 mAs, and
images were reconstructed with a 1.0-mm slice thickness. Images were resampled
to 3 times the original voxel resolution (resampled range, 0.20-0.25 × 0.20-0.25
× 0.33 mm), and each bone was segmented using Amira software (Version 6.0;
Thermo Fisher Scientific).23
Next, a custom dual fluoroscopy system (Radiological Imaging Services)
validated for hip imaging1 (link),6 (link),10 (link)
was used to obtain images of participants’ hips in a neutral standing
position with feet hip-width apart. Images were collected at 100 frames per
second, with energy settings ranging from 78 to 100 kVp and from 1.9 to 3.2 mAs
for tube voltage and current time product, respectively.
