Irving, B.J., et al. Computer assisted detection of abnormal airway variation in CT scans related to paediatric tuberculosis. Med. Image Anal. (2014), dx.doi.org/10.1016/j.media.2014.05.007

Interactive figures that illustrate the method are provided below. A modern webgl compatible browser is required to view these figures.

PCA mode 1

(+ λ → 0 → - λ)

Click and drag figure to rotate. Scroll to zoom.

Move the slider to show the variation along one statistical mode

Slider for each transform

Move each slider to the right to perform template warp

Click and drag figure to rotate. Scroll to zoom.

The airway shape models and matlab code to load and displays the modes of variation are downloadable below

Download model and example codeThe statistical shape models are stored in:

- trachea_ssm.mat - Trachea-LMB-RMB
- rmb_ssm.mat - RMB-RUL-BI

- Running demo1.m illustrates how the data can be loaded in matlab and visualised.
- For a selected mode of variation is produces three plots of the mean shape, and 3 standard deviations along the mode of variation.
- Figure 1 shows just the ROI and Figure 2 shows the ROI in terms of a representative airway
- The representative airway is just for illustrative purposes
- These figures can be rotated to view the 3D shape

The authors intend to release parts of this analysis algorithm
