Description	Není k dispozici (cs) Ultrasound B-mode images of thyroid gland were previously analyzed to distinguish normal tissue from inflamed tissue due to Hashimoto's Lymphocytic Thyroiditis. This is a two-class recognition problem. Sensitivity and specificity of 100% was reported using Bayesian classifier with optimal texture features. These results were obtained on 99 subjects at a fixed setting of the sonograph, for a given manual thyroid gland segmentation and sonographic scan type (longitudinal, transversal). To evaluate the reproducibility of the method, sensitivity analysis is the topic of this paper. A general method for determining feature sensitivity to variables influencing the scanning process is proposed. Jensen Shannon distances between modified and unmodified inter- and intra-class feature probability distributions capture the changes induced by the variables. It is shown there are stable features insensitive to small sonograph gain changes and gland segmentation.
