ELECTRONIC COLON CLEANSING METHOD FOR VIRTUAL COLONOSCOPY |
摘要 |
A method for electronically cleansing a virtual object formed from acquired image data (Figure 1, 100) converted to a plurality of volume elements is provided. The present method allows individual volume elements or voxels, to represent more than one material type. The method includes defining a partial volume image model (Figure 1, 110) for volume elements representing a plurality of material types based, at least in part, on the measured intensity value of the volume element. The material mixture for each of the volume elements representing a plurality of material types can be estimated using the observed intensity values and the defined partial volume image model. The volume elements representing a plurality of material types can then be classified (Figure 1, 130) in accordance with the estimated material mixture. For electronic colon cleansing, the method includes removing at least one classification of volume elements when displaying the virtual object. |
