Groundwork Projects

These projects investigate (and resolve) scientific questions underlying QIBA Profile work.

VolCT - Group 1A - Analyze Bias/Variance where Ground Truth is Known Deterministically
VolCT - Group 1B - Focus on Volume Change Analysis of Pulmonary Nodules in Diagnostic Settings
VolCT - Group 1C - Model Sources of Variability from a Systems Engineering Analysis
VolCT - Group 3A - Characterize variability due to algorithms (using phantoms / clinical data)
VolCT - Group 3B - Characterize clinical utility/efficacy with respect to clinical endpoints
VolCT - Colorado Group - Quantifying variability in measurement of pulmonary nodule

Radiology 2007 - Coronary Calcium Scoring - This paper by Dr. McCollough et al is may be seen to be analaogous to our work in that it addresses similar issues (e.g. achieving "standard" noise levels). It could be thought of as an early draft of a Calcium Scoring profile, including both groundwork and equipment specifications.
