Short description: 
SEGAMS: A tree-structured hierarchical data processing system. The software system of a gamma camera connected to a minicomputer that can be used to acquire and evaluate the most common types of nuclear medicine studies used in clinical routine.
Description: 

SEGAMS is a hierarchic (tree-structured) nuclear medicine system, in which the doctor can control the whole evaluation process in the form of a dialogue with the help of an alphanumerical display connected to the system. Our main aim was to develop a „doctor-oriented”, „doctor-proof”, and clearly arranged system. For this we made sure that in every work-phase the user sees all possibilities of the system from which a choice can be made that is appropriate from the medical aspect. Acquisition possibilities: Static study: imaging the distribution of radioactivity from different directions. Dynamic study: following in time the change of distribution of radioactivity through an image sequence. Major processing possibilities: processing individual images, frame-algebra, Region Of Interest (ROI) selection, producing time-activity curves over a ROI, …
