Project Description
Objective
- Calculate the ratio between the diameters of aorta and pulmonary artery, as a biomarker of acute exacerbations of COPD.
- Calculate in a fast way the ratio of the major and minor axis of the aorta in a chest CT slice where the pulmonary artery is clearly visible. This ratio is a biomarker used in pulmonary vascular disease and has been associated with outcomes like exacerbations.
For more information about the medical need: Pulmonary Arterial Enlargement and Acute Exacerbations of COPD
Approach, Plan
- Phase 1:
- Give the expert a simple mecanism to measure the aorta and pulmonary artery is in the best slide possible (this could include an automatic tool to detect which is the best slide)
- Calculate the ratio automatically.
- Phase 2:
- Completely automatic measurement of aorta and pumonary artery for an expert validation.
Progress
- Markups are automatically set according to the structure that the user has selected
