The present invention relates to a method and apparatus for the
construction and/or use of multidimensional fields that can be used for
high-resolution detection and characterization of features within objects.
The multidimensional field is constructed from data that is collected by
an array of radiation detectors that substantially surround the object
under study. The detected radiation is produced by an array of radiation
sources and is subsequently scattered, reflected, transmitted, or
diffracted by the object under study and any features within the object
under study. In particular embodiments of the invention, the radiation
that is used is ultrasonic radiation and the object under study is human
or animal tissue or an organ. In this case, the invention permits the
detection and identification of cancer by an intelligently trained
evaluation system.
