(57) Abstract :
The invention provides a digitally implemented system for normal and early classification of
radiological image data. The system comprises, input member, user interface, database, attribute
extracting member and output member. The database includes learning routines, fuzzy instruction
set and supplemental data. In normal classification mode unique histogram and spatial median
values for intensity and slope of selected pixel are calculated by the attribute extracting member.
Fuzzy instruction is applied to the calculated attributes to classify the selected pixel according to
the tissue type. After classification different output images are displayed at the output member,
each image showing only pixels of a particular tissue. If the user selects early classification mode,
a portion of the image is selected to be early classified and is stored as reference image. Attributes
namely, prototype count, bin values and pixel count are calculated for the reference image by the
attribute extracting member. Same image is analyzed for all the attributes after certain temporal
periods during which radiation therapy is performed on the tissue. The comparative study of
attributes before therapy and after therapy is performed to conclude if connected tissue is
positively diseased.
