Case Study: Femur Analysis with UKE, Hamburg¶
In collaboration with the Institute of Osteology and Biomechanics, UKE we used XamFlow and CLIP to analyse subchondral cysts in femoral heads.
“I’m really impressed!” – Felix Schmidt, Institute of Osteology and Biomechanics, UKE
Multiple samples of femoral head measured with SCANCO XtremeCT II
17 GB per image
6 images analysed initially
We used CLIP to implement four stages in a multi-object segmentation workflow:
Bone mask and hull
Cartilage mask and loss area
Subchondral area mask
The CLIP curvelet filter was used to identify the subchondral area.
