It is well known method that an exposure timer is examined with a spinning top and it also well known fact that we can find some density distribution on its strobo patterns, respectively. The authors have developed a strobo scope which has property of a constant rotating speed with a synchronous motor, and analyze the strobo patterns comparing with oscillograms of X-ray tube voltage waveforms and fluorescence intensity waveforms taken simultaneously with the strobograms. X-ray atrobo scope; ^*1 & 0.5 mm lead slit, thickness 4 mm. ^*8×10 rotating cassette coupled with a synchronous motor. ^*180 RPM constant rotating speed. Result; It can be aproved that the strobo pattern shows following high-tension phenomena, 1. Normal or abnormal pull in, pull out phase. 2. Sarge voltage, being or not. 3. X-ray intensity change during an exposure. 4. X-ray tube voltage waveform distortion. 5. Other abnormalities of X-ray generators. By means of this equipment, one working for a radiological department, can know easily such high-tension phenomena as surge voltage, X-ray intensity change and X-ray tube trouble etc which occur during an exposure, without any high-tension technique at all. It can contribute to a short time exposure technique such as 1 millisecond〜100 milliseconds.

About half of the total medical irradiation doses is said to be accounted for by the genetically significant dose during the fluoroscopy of alimentary canals. It is important for us radiological technicians, therefore, to know how irradiation doses during the fluroscopy influence on the patient's gonads depending on their conditions and ages. This research can be a step toward a better medical treatment. Firstly, of all the patients treated with the gastric fluoroscopy, the percentage of the reproduction patients whose ages are 40 or less was calculated. Then the study was made as to whether there was any difference in irradition doses on the gonad of a patient, depending on wheter he was over 40 or under 40. This study also revealed whether the therapist has given careful consideration to the genetic influence of the irradiation dose. As a result, it was found that radiologists has given special attention to the progenitive condition of the patient by reducing the time needed for fluoroscopy. However, no difference in irradiation doses based on the patient's age was observed in the treatments by non-radiologists.

In 51 eases with cerebral vascular disease (CVD), dynamic study of radioisotope was done as screening using r-scintilation camera connecting minicomputor. Intraveneous bolus injection was performed 10〜15 mCi of ^<99m>TcO_4^-. CVD can be diagnosed early and easily from the following data. 1) demonstration of space occuping lesion. 2) difference between right and left area in clearance curve. 3) arm-to-head circulation time, mean transit time. 4) pattern of clearannce curve.

In the clinical study using scintillation camera, the efficiency of camera must be checked before the study. One of the important parameters to decide the accuracy of the data from the camera is the uniformity of the image. In this study, a flat-field radioisotope source was developed to check the uniformity of the scintillation camera. The advantages of the flat-field source were as follows : the detector was not contaminated by the handing of this source, the vessel wall was thin, so the absorption of radioactivity by the vessel wall was decreased washing inside the vessel was easy and radioactivity did not remain in the vessel, transportation of the vessel was easy and there was little danger on damage.
