Three dimensional heat-induced echo-strain imaging is a potentially useful tool for monitoring the formation of thermal lesions during ablative therapy. Heat-induced echo-strain, known as thermal strain, is due to the changes in the speed of propagating ultrasound signals and to tissue expansion during heat deposition. This paper presents a complete system(More)

C-arms are increasingly being used to assist in a large number of surgical procedures. Fairly accurate and fast pose estimates are needed for non-encoded c-arms that are commonly available in most operating rooms in order to attain quantitative feedback from the x-ray images. We propose the use of an image-based fiducial composed of a set of coplanar(More)
