Several institutions have accumulated clinical experience with the annular array as well as with the Sigma applicator. There exist only limited data in comparison of both heating devices possibly favoring the annular array over the Sigma applicator with regard to tumor temperatures and acute toxicity. The objective of this study was to record temperature distributions at identical sites in tumor and normal tissue in the same patients treated with each device.
