Individual dose monitoring has been carried out using TLD to assess the radiation exposure to radiotherapeutic staff during the interstitial implants with ^<226>Ra-needle, ^<198>Au-grain and ^<192>Ir-hair pin and/or single pin for oral carcinoma. The results measured wiith TLD were expressed as specific exposure in terms of mR per mCi x min. to compare the exposure from each implant. The skin doses for the operater and the assistant during both ^<198>Au-grain and ^<192>Ir source implants were about one thirds of ^<226>Ra-needle implants on the left forefinger, chest and abdomen respectively. Particularly the skin dose with ^<192>Ir source was successfully lower than the dose with ^<226>Ra-needle by the effect from afterloading system.

A patient complaining of metatarsalgy has to be X-ray photographed in the erect position with overload imposed on the foot. We tabulated the dataon the position and the angle of incidence so as to facilitate the determination of those two factors in X-ray photographing which permitted shadow examination.

An accurate measurment of anteversion angle of the the hip is necessary for diagnosis of hip joint diseases. Kai's, Takagi-Nakura's, and Ryden-Crane's methods are well known for measurement of this angle, however, an accurate angle cannot be obtained in these methods. In this study, we evaluate the technique of measuring more accurate anteversion angle of congenital dislocation of the hip (CDH) by axial projection of the hip.

To obtain clear X-ray films of the lumbar spine of the patients with spinal cord injury who were hard to maintain supine position, two radiographical methods were carried out. In method I the SID assumed to be the curvature radius, around 60 cm, and in method II the SID was fixed 120 cm and the tube angle was 7° toward head. Our study indicate that the radiography of lumbar spine in the method II was clear compared to the method I, since the SID of method I was quite short.

Cervical spondylosis is a condition in which there is a progressive degeneration of the disc leading to characteristic changes in the surrounding structures, especially bones and nerves. Plain radiograph for detecting of these characteristic changes have been limited because the patients of the cervical spondylosis has distorted alignment and the shadow of superimposed structures. Then tomograph is frequently useful in delineating the accurate evaluation of the cervical spine. It is necessary to demonstrate the isolated anatomical section cope with lordosis, distorted alignment at the single tomographic plane. Various technical problems such as determination of precise tomographic plane, safe and satisfactory immobilization, proper centering of the beam are not yet resolved. The authors describe the new attempt of tomographic technic for cervical spondylosis.

It has been considered that the rheumatic diseases affects the cervical spine as time goes by. To recognize detailed changes, 3.5 times magnification tomography is suitable. As for the orbit of the X-ray tube, the trispiral motion is found to be good, and the exposure angle of "34-29-24" is the best among "34-17-0", "34-26-18" and "34-29-24". A front view of upper cervical vertebral spine is obtained by placing the anthropological base line of the head perpendicular to the film. A lateral view should be taken at the accurate lateral position because the measurement of A.D.I. is the main purpose in this examination.

The stress radiography of ankle joint is a means which find a ligamentous lesion by stressing ankle joint and measuring talar tilt. This method is very useful as a screening examination. The patient's foot is fixed on the surgeon need not keep the foot during the examination. We understand the valve of this unit, because we could find out ligamentous lesions and neglected fractures if they are taken by simple radiographs. This unit was originated by Dr. Y. Shibata, division of orthopaedic surgery, Kainan Hospital.

Holding apparatus for arthrography of the knee is greatly needed. A device is manufactured and an experimental trial on its applicability is presented. The fixing mechanism designed allowed a quantitative stretching on the designated direction for a maximun opening of the joint space. Also, since the knee was immobilized by the force provided from four point, its avoided problems of movement or twisting. Moreover, X-ray photogram of great accuracy and good reproductibility was made available, causing minimun pain to the patient which easy the examination. The result of this trial indicated a promissing use since prevented unnecessary exposure of technicians.

Routine posteroanterior X-ray photos of cervical vertebrae doesn't always give satisfactory view of 3rd and 4th vertebrae. To obtain clear X-ray photo of whole cervical vertebrae, special apparatus for head fixation was devised. During taking X-ray photo we can keep the patient's mouth open and close without moving head in this apparatus. By this method clear X-ray photo of entire cervical vertebrae 1st through 7th and Luschka's joints were obtained constantly.

This experimental production of supplementary accessory is for taking picture between 1st lumbar vertebra and 2nd sacrum without distortion while relieving pain of lumbar vertebra patient. This accessory is made of foamed styrol resin in hexdral right-angle trapezoids shape. Two will be used in radiographing. One placed in the head position and other hip position. Radiograph will be taken with patient lying face upward on these two. This radiographing technique was used in 412 cases in 396 cases this technique gave positive results and in 16 cases negative. However in cases which gave negative results, there are possibility of having better x-ray picture by adjusting the position of supplementary accessory.

Calcification is one of the most important sign in the roentgenologic diagnosis of cancer of the breast, though it is also often found in benign lesion. It is generally accepted that calcifications in cancer are tiny, dot-like or somewhat elongated, innumerable and irregulary grouped very close together in an area of the breast such as "grouped calcifications". Analysis of these calcifications is very usefull not only for differentiating other benign lesions but also detecting early or minimal breast cancer. In view of this point we have introduced and studied magnification compression mammography in order to obtain superior image quality of microcalcification than conventional contact mammography since 1979. Now, analysis of breast calcifications is improved most by the magnification compression spot mammography ; sharper definition of individual calcifications is produced. With performing this technique, we have invented the supplementary equipments for decreasing examination time and x-ray exposure, which can automatically and exactly devide a 8×10 in. film in quarters, and so, we have good results.

We've manufactured an easy clairvoyant compensating filter for use in P.T.C. inspection. Its manufacturing was fairly easy, and its effect was big. Using this compensating filter, we could make P.T.C. inspection easy, and reduce the quantity of the radiant rays to fifty percent. We could freely process Kyowa-glass XA, because it was about the same nature as acrylic resin. From the view-point of the photographing subsidiary tool, the meaning of this compensating filter was great.

For all vertebra radiography we made a density compensation filter to uniform of all vertebra density. The filter is composed of three materials as acryl plate, copper plate and magnet. And the filter is attached with magnet to the metaric panel of the tube port in front of a collimater. We have tried 1,500 cases with this system and found its effectiveness. The results are as follows.

It is sometimes difficult to obtain a well-positioned radiograph on a special projection or on an unusual patient's position fullfilling a physician's demand with a single exposure. To solve these problems, we made a new device using a digital memory unit which makes an image on CRT with a minimal radiation dose to a patient (1/100-1/150 less radiation when compared to an ordinary exposure). This new device when using just before obtaining a radiograph easily identifies whether a patient is well positioned or whether the angle or the collimation of an X-ray tube is properly set and would, therefore, eliminate unnecessary repeated exposures.
