We have developed an original fixing device for applicators of tandem and ovoids sources during high dose rate intracavitary therapy for uterine cancer. This device consists of a pan head and an elevator of tripod for the camera and has special connectors to fit to various kinds of applicator during this treatment. Efficacy of this device were analysed using X-ray film (A-P, L-R) of the patients at the beginning of treatment. From August 1978 through August 1985, a total of 320 cases (total number of treatments : 1321) in clusive uterine cancer had been treated with this device. The following items were investigated : changes in the coodinates of both ovoid sources, correction rate(%) of point A and coordinates of the weighted geometric center. Favorable results were obtained. This device have several following merits : (1) The appropriate dose distribution is obtained by shifting the position of the applicators of the tandem and ovoids sources carefully on this fixing device. (2) Fixation and modification of the position of in vivo dosimeter ICD-5 are easily achieved. (3) Set up and detachment of this fixing device can be easily carried out without disturbing the operator and contamination according to each treatment. In conclusion, this device is very significant for intracavitary treatment results in the near future.

In the stereoscopic observation of the images taken by the method of rotation of an opposed X-ray source and image receptor around an object or the rotation of an object itself with X-ray and image receptor combination fixed, the equations that indicate the location of the stereoscopic image point which corresponds with a point of the object are derived analytically and geometrically. The results are visualized using examples by computer graphics to see how the stereoscopic image with the method is observed. The equations and graphics show that the stereoscopic image by this method necessarily distort convexly or concavely along the horizontal direction. To minimize other distortions, the following conditions are necessary according to the equations. (1) Directions of X-ray exposure and observation are coincident. (2) Rotation angle in radian is equal to the value of inter-pupil distance divided by the focal spot to film distance. (3) Observation distance is equal to the focal spot to film distance. Two images for both eyes equivalent to the stereo-radiographs of a rectangular wire frame taken by the method in usual parameters are also drawn by the computer. By stereoscopic observation of the images, the above-mentioned matters can be comfirmed. As the convex or concave distortion is not recognized in the observation, the three conditions give stereoscopic image with practically no distortion in the examples.

Iodine-125-PTH was purified using affinity gel column chromatography. The column was prepared with activated CH Sepharose 4B coupled to PTH antiserum. Radiommunoassay (RIA) using I-125-PTH (1-34) purified by affinity chromatography with anti-PTH (1-34) Sepharose was sharped than those purified by gel chromatography with Bio Gel P-4. The intra-and inter-assay coefficients of variation were 7.3% (n=5) and 1.5% (n=5), respectively, in the RIA system for PTH (1-34) in human serum. The minimal detectable concentration of PTH(1-34) was 5 pg/tube, and 50 pg/ml in serum was possible to assay. These results indicate that the purification of iodine-125-PTH (1-34) using affinity chromatography with anti-PTH (1-34) Sepharose is a useful method for the establishment of the high sensitive RIA system.

Since the 1950s, the computer has been utilized to deal with radiotherapy parameters and patients' records. .To university hospitals, cancer centers and other major institutions, a national survey was carried out concerning actual circumstances of automation in radiotherapy. Questionnaries consisted of items regarding identification, autosetup and the record system. In this study, with the results of the national survey and our experience concering the automation system, the problems of automation in radiotherapy, are reported on. Results 1. Automation system is essential to save man power and keep the therapentic parameter accurate everyday. 2. A false operation should be able to be easily confirmed. 3. Automation system should have the following charcteristics ; safety for patients, simple to operate and inexpensive.

Two fields exist in radiological technology : one having a direct relation to patients, and the other having only an indirect relation to them. The field in which electronics plays a main role is developing very rapidly today, and its application to radiological technology is really remarkable. Due to this, automation of radiological equipment will be greatly accelerated. However, great care must be taken concerning automation in this field in which the patients are in direct contact with the system, for it will be very difficult to obtain the full confidence of patients if there is table automation of the process. In spite of great advances in automation, education on automation should be mainly focused on basic knowledge of the structures and functions of the automated apparatus. With the progress of automation, the need for quality control of the highest order will become more and more important. A four-year college education is desirable to train well-qualified radiological technologists who can cope with the rapid progress being made in radiological technology.

In recent years, the automatic system has come to be widely used in the industrial world. This system is also being applied to the medical field. However, the system does not always work well in the Radiology Department. This is because it is introduced only in a part of mechanical system. The automatic system does not work well unless it is in balance with the whole mechanical system. How should we introduce the automatic system when we consider our patients to be the chief aim? In this paper, I am going to pursue some problems in order to introduce the automatic system regarding X-ray examinations.

Over the last 10 years, a large number of automatic radiographic apparatuses such as X-ray CT, DSA, US and scintillation camera with a data processing system and so forth have been installed in the department of radiology. Almost all of these apparatuses were connected to the computer. However, it has been pointed out that these computer combined man-machine-man systems involve run the risk of taking away all humanness both for the patients and operators. In this paper, we carried out an evaluation on these types of equipment that have been installed in our hospital and have provided the following conclusions which stress that the greatest of consideration must be taken when installating these apparatuses. 1. Respect the humanity of the patiants 2. Safe operation 3. High accuracy.
