Objective symmetry detector method for gammaencephalography. III. Diagnosis of abnormal 99TcmO4 distribution in the skull.
The objective classification of results of the previously described symmetry detector method for gamma encephalography is reported. The different evaluation parameters were chosen after comparing their detectability in different subregions of the head or as a result of findings in certain patients. The detectability was estimated from the results of phantom measurements related to the normal ranges of evaluation parameters. The borders of the classification criterion are discussed in relation to the number of evaluation parameters used.
