Abstract
A diagnostic imaging system generates a three-dimensional display from a series of two-dimensional slice images. A region of interest, defined from a boundary of interest, is selected from one slice and is extrapolated to subsequent slices. Pixels representative of the boundary of interest are isolated and represented by three vectors having an equivalent entries in each. First and second vectors store data representative of first and second coordinates for pixels within each slice. Entries in the third vector corresponds to physical properties of a specimen at a location defined by corresponding entries in the first and second vectors. Areas representative of boundaries of interest falling between slices are extrapolated from vector data from slices neighboring the area. This is accomplished by a linear interpolation of elements of the set of smaller vectors to a number equivalent to the entries in the neighboring larger vectors. Next, a linear extrapolation between respective elements of the lengthened vector and the longer of the vector is made. Finally, a linear interpolation of the intermediate vector to a number of vector elements intermediate the larger and smaller of the ne…
