In function tests of thyroid gland by using radioistope, the greatest care is required to get correct results. Out of many problems of these function tests, the technical ones of the scintigram of thyroid gland were taken up and studied. In these studies, a scanning apparatus with Mac Intyre circuit was used. From these studies, the following were concluded. 1.The life-size image of the object in which radioisotope is distributed evenly is described in scintigram regardless of its radioactivity, only by using discharged pulse of the object of which from is proper. 2.In describing scintigram, the scattered X-ray on the patient does not increased only when a very thin collimator is used. Therefore, in these experiments, energy was cut off when the electron volt reached to some 50keV.
