| Résumé : | Digital image-based elasto-tomography technology relies on obtaining high-resolution images of a breasts surface under high-frequency actuation, typically in the range of 50-100 Hz. Off-the-shelf digital cameras and imaging elements are unable to capture images directly at these speeds. A method based on strobe imaging is presented for obtaining the required high-speed image capture at a resolution of 1280 times 1024 pixels and actuation frequency of 100 Hz. The final working system produced images that enabled effective 3-D motion tracking of the surface of a silicon phantom. The motion is tracked accurately using a novel Euclidean Invariant signature method. |
