The overall objective of this research investigation is to develop a methodology for displaying microwave dosimetric data. Special emphasis was placed on developing a method for evaluating the spatial variations of absorbed microwave energy by specific organs and subdivisions. Techniques were developed by a computer and displayed on an image in pseudocolor. Manipulation of the data using the image system allows the operator to highlight organ subdivisions within an image. A cubic spline interpolation program was developed to uniformly expand the data set for presentation on a large format display. A two segment enhancement curve was developed which gives the operator the capability of creating his own lookup table for pseudocolor translation of images stored in refresh memory. The results to date show that pseudocolor imaging is an effective method of analyzing microwave dosimetric data. Additional processing algorithms need to be developed and the system hardware should be optimized for image processing. Keywords include Image processing, Cubic spline interpolation, and Two segment enhancement curve.
