Popis: The aim of this study was to improve uterine target localization in cervix cancer radiotherapy by improving ultrasound image quality. This was achieved through the development of a novel technique called “3D extended-aperture spatial compounding” (3D-EASC), which used the optical probe-tracking technology of the Clarity system to improve ultrasound image quality by extending the field of view, reducing ultrasonic speckle, and enhancing the ultrasound amplitude from tissue boundaries. Changes in image quality due to 3D-EASC were quantified using non-compounded image volumes as a reference in both phantom and in vivo studies. 3D-EASC increased the contrast-to-noise ratio, maintained spatial resolution, and improved the mean observer ranking of image quality of in vivo images of the uterus compared with non-compounded images.
