From: Clinical evaluation of semi-automatic landmark-based lesion tracking software for CT-scans
Experimental setup. In a consensus assessment of three readers the centre of each RECIST target and non-target lesion was marked in every baseline and follow-up CT-scan (red X). Next, the readers applied the lesion-tracking software by clicking on each defined centre of the lesions in the baseline CT-scans. Thus, the software automatically navigated to the predicted corresponding location in the follow-up CT-scan (yellow crosshair). The deviation between lesion’s centre and the navigation result of the software was documented as distance (blue dotted line) in all three special dimensions (cranio-caudal, ventro-dorsal, lateral).
