[Dosimetry with Imatron].
Although the Imatron is based on a technology different from that of conventional CT scanners, its physical principle is comparable. For this reason dosimetric studies were carried out in the same manner that is by employing small thermoluminescent dosimeters. The results obtained with this technique for the four specific protocols of the Imatron indicated surface doses between 0.7 and 15.7 cGy and between 0.1 and 7.2 cGy at surface of the slice. The weakest doses were recorded during cardiac exams for which this type of CT scanner was designed and developed. This highest doses were delivered for scans of the head region.
