An efficient medical image fusion method has been proposed based on contourlet transform and multi fusion rules. The multimodal medical images were first decomposed using the contourlet transform then fusion rules were applied to low frequency components and high frequency components of contourlet coefficients. For low frequency components principle component analysis (PCA) method was adopted. While for high frequency components region based contourlet contrast was adopted. The final fusion image is obtained by directly applying inverse contourlet transform to the fused low and high frequency components. Using four image quality indicators experimental results showed that the proposed method give extensive fused image on multimodality CT/MRI.

    ABSTRACT: Ultrasonography is an invaluable and widely used medical imaging tool. Nevertheless, automatic texture analysis on ultrasound images remains a challenging issue. This work presents and investigates a texture representation scheme on thyroid ultrasound images for the detection of hypoechoic and isoechoic thyroid nodules, which present the highest malignancy risk. The proposed scheme is based on the Contourlet Transform (CT) and incorporates a thresholding approach for the selection of the most significant CT coefficients. Then a variety of statistical texture features are evaluated and the optimal subsets are extracted through a selection process. A Gaussian kernel Support Vector Machine (SVM) classifier is applied along the Sequential Floating Forward Selection (SFFS) algorithm, in order to investigate the most representative set of CT features. For this experimental evaluation, two image datasets have been utilized: one consisting of hypoechoic nodules and normal thyroid tissue and another of isoechoic nodules and normal thyroid tissue. Comparative experiments show that the proposed methodology is more efficient than previous thyroid ultrasound representation methods proposed in the literature. The maximum classification accuracy reached 95% for hypoechoic dataset, and 92% for isoechoic dataset. Such results provide evidence that CT based texture features can be successfully applied for the classification of different types of texture in ultrasound thyroid images.
