[Poster Presentation] Improving Accuracy of Airway Wall Thickness in MDCT Using a Deconvolution Technique: A Swine Phantom Study
Sang Joon Park, Jin Mo Goo, Jong Hyo Kim (Seoul National Univ.)
Abstract (in Japanese) (See Japanese page) 
(in English) Airway wall thickness (AWT) is an important bio-marker for evaluation of pulmonary diseases such as asthma, and bronchiectasis. While an image-based analysis of the airway tree can provide precise and valuable airway size information, quantitative and qualitative measurement of AWT in MDCT images involves various sources of error and uncertainty. So we have developed an accurate AWT measurement technique for small airways with deconvolution approach. To evaluate performance of these techniques, we used a swine phantom with small airways to have three different sizes of wall thickness. The wall thickness of each airway was obtained with full-width-half-maximum (FWHM) method for the line profiles before and after deconvolution processing. Results show that significant improvement was achieved over the conventional FWHM method in the measurement of AWT.
