Thyroid scintigramm is the only important diagnosis method. However, thyroid scintigramm image is much influenced by such elements as the state of the diseased part, the apparatus and drawing method etc. Therefore the reappearance of the image is hardly possible and the drawing of the full-sized image is almost impossible. Different size images are got from one and the same patient, so it is questionable to use scintigramm image for comparison, tracing diseases and weighing thyroid gland etc. The standardization of thyroid scintigramm is much desired. The author studied the drawing method of full sized image as a preparation of standardization of thyroid scintigramm. He originated "The regulation of energy zone"in which the index of the drawing condition is the percentage of I^<131> taken in thyroid gland. It is concluded through the experiments that this originated method takes advantages over the usual methods : 1) The full-sized image recorded with this new method has smaller background and is more reliable. 2) The conditions of the drawing are selected easily and the reappearance of the image is more possible. 3) Moreover, it is possible to get a satisfying full-sized image, if the dose of I^<131> is adjusted according to the percentage of I^<131> intaken.
