Key Investigators

  • U. of Iowa: Eric Hoffman, Janice Cook Granroth, Keith Gunderson
  • Kitware, Luis Ibanez


The research is funded by SARP -- Severe Asthma Research Program
Severe asthma affects a small subset of asthma patients but uses a disproportionate amount of health care resources. It is also responsible for a significant amount of the morbidity and mortality associated with asthma. The purpose of this study to establish a collaborative program to investigate the mechanistic basis for severe asthma and how it differs from mild-to-moderate asthma.

Technical specifics

  1. Compare the results of different scanner brands and kernels quantitatively
  2. Investigate homoegeneity (w/ respect to objective 1)
  3. Investigage MTF (w/ respect to objective 1)
  4. Investigate airway size and wall thickness algorithms (w/ respect to objective 1)

Approach, Plan


Add rotational registration feature.
Investigate porting issues


Pre-NAMIC status

Objective 1,2,3 completed
Objective 4 is in progress

Post-NAMIC updates

  1. Registration details understood, coding underway
  2. Two new segmentation approaches to be investigated (Model-based & Projection/HoughTransform2DCircles)
  3. CMake improvents & CTest/ CDash integration begun (i.e. introduction to CMake-ish tools)
  4. Regression & Uniting testing being added
