Due to the rapid progress of the method for X-ray exposing technology, gastro-bowels exposing technology and fluorography on X-ray TV-system has been moved to an automatic system which is controled by exposing value, however, in the field of Chest X-ray Exposing Technology, an exposing value controling system has not come into so wide use, and it is very difficult to find the institute where fully-automatic exposing controling system is used at their chest exposing works. There is an idea to control the exposing value automatically by setting up the system which shall be able to change the exposing voltage and the current byresistor to the photo-timer which has been used. Then trial instrument which was designed from the idea is manufactured and, here is a report from the tested results of the instrument.

The image of the apex on a X-ray picture is frequently overlapped by those of the clavicular and upper ribs, resulted in obscureness of the details there. These overlaps are related to the hight of the focus of X-ray tube. Many literatures have refered the hight of the focus when the Chest X-ray picture was taken, and the proper hight was ranging from the 4th to 8th thoracic vertebra, but it is mach frequently said that the hight of the focus showed be 5th to 6th theracic vertebra. Howesrer, on the chest X-ray picture 5th to 6th thoracic vertebra is not corresponding to the center of it. The anthor shows in most cause, male or female either, that the center of lung on a X-ray picture comes to 7th to 8th thoracic vertebra, which is well corresponding to the 7th spinous process on the surface. The relat ionship between the hight of focus and the overlap of images on the apex were examined on many cases. The results shows that the indiviaual differenees of the body structnre have much inferences upon the overlap of images than those of hight of the focus. Usually, the slight gradient of the upper body can reduce the overlap of the image, but, this method is difficult to be adapted as a standerd chest X-ray picture.

Arthrograph of the knee was devised by ROBINSON, WERNDORFF in the early 20th Century. Air (Negative Contrast me dia) was Used at that time. BIRCHER developed double contrast arthrography with air and positive contrast material (Abrodil), forming the basis of the present method, LENNART, WEHIIN and ANDR'EN advocate the horizontal X-ray technique. We studied on the method of double contrast horizontal X-ray beam arthrography and report some technical consideration.

We tried to project at the position of postero-anterior in case of radiographic examination on lumbar spine, though the routine antero-posterior position was popular. We get better result especially on the view of the intervertebral space. So we concluded that our new method was preferable to that of the general antero-posterior position, and would recommend its wide use.

The authors have gained various experiences in the medical application of X-ray television installations for the past ten years since we installed the remotely controlled X-ray television unit in the Center for Adult Diseases, Osaka which was the earliest one of the remotely controlled radiographic -fluoroscopic tables used in Japan. Recently several X-ray technicians including the author having wide experience in the practical utilization of the X-ray television device had the opportunity to discuss the present situation and the further development of this device. The opinions discussed in this meeting were analysed by using KJ method and reported in the present communication.

Standard radiographic examination of the lumbar spine by antero-posterior oblique projection is needed for investigation of the body of vertebra and pars interarticularis. The present study was designed to measure the X-ray findings of them by postero-anterior oblique projection as compared with the ones by antero-posterior projection. Examination by postero-anterior oblique projection shows the body of vertebra and intervertebral space with greater clearity than ordinary antero-posterior projection. But pars interarticularis is enlarged in X-ray findings. So x-ray tube should be set up at 140cm of film-focus distance.

We examined foundamental studies of diverging collimator with Aloca XYS-203 type scintillation camera and the results as follows. 1) There is a 10〜20% loss of sensitivity but no loss in resolution when the diverging collimator is compared with it's parallel hole designed for the same energy range. 2) A geometrical formation of diverging collimator caused more vertical distoration than was considered acceptable. 3) The scintiphotography has a star pattern formation by the influence of the shape and arrangement of the holes and high energy γ-emitters. 4) The Moire pattern formation is demonstrated by the variation of angle between arrangement of the holes and line phantom. 5) It is proposed that such artifacts (star pattern and Moire pattern) may be eliminated by providing a moving collimator in standard Anger camera. 6) we think that the diverging collimator is useful, because this collimator have a large field of view than necessary, except the geometrical distorations.
