  9. The Image Tagging Interface A 2-D X-ray image is read, and then notes are entered into the radiologist’s report

  10. <feature type="Ellipse" label="Tumor"> <ellipse> <xCenter>277</xCenter> <yCenter>278</yCenter> <xRadius>44</xRadius> <yRadius>34</yRadius> </ellipse> </feature> Instead, a 3-D image can be annotated by the radiologist with searchable tags, so the notes can be integrated with the image in a relational database system. The Image Tagging Interface <feature type="Ellipse" label="Tumor"> <ellipse> <xCenter>277</xCenter> <yCenter>278</yCenter> <xRadius>44</xRadius> <yRadius>34</yRadius> </ellipse> </feature> Poster R3B P4 - "Online Image Tagging System"

  11. 4-D Radiotheraphy – 3D + Time • New visualization tools to allow physicians to rapidly segment and identify regions of interest in 3D or 4D • Leverages SCI-Run (Univ. of Utah) – a visual programming problem solving environment • The total time for treatment planning can be reduced by allowing more efficient analysis of size, shape, and movement of tumors • Present work focuses on enabling accurate physical measurements in our visualization environment Poster R3B P3 - "Development of Visualization Tools for 4D CT Datasets"
