| dc.description.abstract | Small point targets can be difficult to detect in medical ultrasound images, but they are important in applications such as imaging of breast microcalcifications, kidney stones, and point tracking. The thesis explores how to enhance and detect point scatterers. It introduces new multilook techniques that optimize the spatial frequency spectrum of the image. Modern software methods affect the image statistics and the point detectability. The thesis presents an objective methodology for assessing the detection performance of point scatterers. | en_US |
