Abstract: The design and development of computer aided diagnosis (CAD) systems is done based on the features extracted from medical images. It will be appropriate to combine the information obtained from different images for better diagnosis. Diagnosis capability of ultrasound elastography and echography are analysed using the images obtained from tissue mimicking phantoms and patient images. The results of this analysis can be used to select the feature set for the design of CAD system for the diagnosis of solid lesions. Ultrasound B mode and elastography images were obtained from the commercial available scanner. Parameters are extracted from the analysis of these images.

Keywords: medical image analysis; ultrasound elastography; echography; strain index; tissue phantom; medical images; image processing; computer aided diagnosis; feature extraction.
