[A method for fast virtual eversion of a colon].
As the existing electrical field method for colon hollow structure virtual eversion is time consuming, a new faster method is presented here to overcome this disadvantage. In the new method, the cross section we used is composed of an orthogonal section and an electrical field section rather than the electrical field section only. We have applied this new method to a series of CT data of a patient for virtual eversion. The result shows that the time cost by using the fast method is only about 1/6 of the existing method, and the image quality is also acceptable.
