In order to provide doctors with comprehensive

visual

and accurate diagnostic information

the 2D and 3D section display method for medical image volume dataset is discussed. For the case of 2D section

by means of human computer interaction

the path of arbitrary section is given by the user

then the operation of quantization and sampling is implemented by virtue of solution train of thought of reverse engineering

each point position along the path is attained

so is each point on the section plane. Through the operation of resampling and interpolation

the 2D arbitrary section display for medical image volume dataset is realized. As to the 3D case

by using the same image sampling and interpolation operation as those in the 2D case to get the texture data array

then in combination with the technique of texture mapping

mapping the texture data into the 3D coordinate space

thus the result of 3D spatial section display is achieved.
