Case study: visualization of 3D ultrasonic data
Georgios Sakas, L.-A. Schreyer, Marcus O.W. Grimm · IEEE Visualization · 1994
3D Ultrasound is one of the most interesting non-invasive, non-radiative tomographic techniques. Rendering 3D modells from such data is not straight-forward due to the noisy, fuzzy nature of ultrasound imaging containing a lot of artefacts. In this paper we first apply speckle, median and gaussian prefiltering to improve the image quality. Using several semi-automatic segmentation tools we isolate interesting features within a few minutes. Our improved surface-extraction procedure enables volume rendering of high quality within a few seconds on a normal work-station, thus making the complete system suitable for routine clinical applications.
