    The relationship of image formation in panoramic tomography to the principle of tomography is not fully understood yet. The authors studies the relationship of image formation between rotational curved surface radiography and panoramic tomography. The rotational curved surface tomography utilizing axial transverse tomographic apparatus was used to narrow beams. In rotational curve surface tomography, images of the test chart were almost the same as those by panoramic tomography. These findings indicate that the panoramic tomographic images are resemble to the zonographic image utilizing the narrow width of a beam, and geometric relations of the cut section and the enlargement ratio, et al., are based on tomography.

    As the contour of a patient's body surface is not usually plane, the use of a compensating filter is recommended for almost all radiotherapy treatment planning in principle. To satisfy these conditions, we have developed a method of automated preparation of compensating filters using the body contour extraction system considering fan-beam, heterogeneous electron density, absorption of filter material. We have used paraffin in making compensating filters for the promptness, simplicity and to make the cost of our process reasonable.

    A compensating filter has been employed for hilar tomography in over 1,200 cases. The visuability of bronchovascular shadows using the filtered tomography was analyzed. The filtered tomograms clearly showed a bronchial tree from the carina to the proximal portion of the lower lobe bronchus in over 95% of the cases examined, except for unfavorable cases due to overlapping lesions. However, as for the left lower region compared with the other regions, the visuability of the anatomical architecture decreased because of the inappropriate shape of the filter and as a result of technical errors. Next, the previous straight type of filter was reshaped so as to be adapt able to the mediastinal structure. As a result, the newly reformed filter improved the visuability of the distal portion of the lower lobe bronchus, central part of left lower vein, and its peripheral part by 23.9%, 5%, and 17.0%, respectively, compared with the previous filter, and reduced the amount of technical errors.

    In order to check for leakage and contamination of 226Ra sealed in a small vessel, the characteristics of the smear method, direct immersed method and indirect sealed method were investigated. The direct immersed method employing toluene was better for sensitivety detecting radioactivity and reproducibility, when compared with the smear method and sealed indirect method. Howerer a problem exists with this method regarding radioactivity in case 226Ra is sealed in a small vessel since radioactivity is irregularly leakaged from it.

    It occured to us that, to know the dynamics of blood circulation in the heart must be a prerequisite for taking chest plain radiograms of the patient under CCU at the optimum radiographing conditions. For verification we compared the chest plain radiograms and the results of examinations of the right heart catheterization by means of the Swan-Ganz catheter made on some 140 patients of acute myocardial infarction and of heart failure under CCU who were received by our hospital and got the following results : (1) In the case of the acute myocardial infarction patients, approximately 80% had P.W.P.s (pulmonary arterial wedge pressure) of 18 mmHg or lower. As to the case of heart failures, approximately 64.9% had P.W.P.s of 18 mmHg or higher. (2) For 19.5% of the patients of acute myocardial infarction and 68.2% of those of heart failure, pulmonary congestion was noticed. (3) A total of 71.7% of the patients of acute myocardial infarction had C.V.P.s (central venous pressure) of 10 mmHg or lower, and P.W.P.s 18 mmHg or lower. (4) For 4.3% of the patients of acute myocardial infarction, accumulation of pleural effusion was noticed. (5) In the case of heart failures, 8 among the 65 patients had vanishing tumors, which were noticed on the right thorax with effusion and cardiac index 2.2 l/min/m^2 or less in all the 8 cases. In the chest plain radiography under CCU it is important to take the above-listed phenomena into consideration. Radiographing conditions under which the radiograms were taken are useful for next opportunities and should be communicated to the succeeding radiographers.

    We changed the treatment conditions for the development of the new cinefilm CFC, examined its fundamental qualities, and compared CFC with CFE under the existing conditions. Low sensitive and very fine grain type CFC cinefilm surpasses CFE in physical qualities ever when it is developed under 30℃ and below 20 feet per minute to make it as sensitive as CFE. When CFC was applied to clinical cases, we could get pictures of better quality than the ones with CFE.

    In cardiovascular diagnosis, free selection of the X-ray direction (angled view or angled projection) is very useful to clear the endocardial structure and the movement of blood stream. Recently the vascular procedures system with multidirectional C or U-arm device is quite universal. This equipment allows the performance of angled techniques without changing the supine position of the patient. In our institute, all of the cardiac catheterization and the angiocardiography is performed by this system. In this paper we describe the outline of multidirectional cine-angiography with C-arm device and clinical or technical subjects for consideration.

    Complex cardiac malformation, among many congenital cardiac diseases, shows various morphological features such as shortening, stenosis and occlusion. The heart rotates and moves to all directions, so that a single bi-plane photography or angle view photography at a certain angle does not give sufficient informations with the photography. Four cardiac catheter examination systems are available at our cardiovascular center, and specific bi-plane photography system is adopted for each equipment of angiography. In the present study, we have examined the optimum positioning for each type of malformation, and the experience of using a specific equipment for taking angiogram in a specific type of malformation will be proposed.

    In this paper technical measurements were made of the cineangiocardiography and the real-time 2-dim. doppler imaging system in valvalar insufficiency. The results obtained suggest more and more infrequent application of the cineangiocardiography to valvular heart disease. However, the echocardiography and the doppler method also have various defects, and the cinecadiography remains important to such cases and/or diseases as cannot easily be detected by other kinds of examinations. Efforts must be made to obtain better diagnostic power through follow-up of images as well as picture processing.

    In the present study, we investigated the clinical usefulness of emergency 2DE in patients with AMI with or without complications, myocarditis, and SBE. The results were as foffows : 1) 2DE was useful in the early diagnosis of subendocardial infarctions associated with bundle brlanch block, where ECG was not useful in detecting AMI. 2) The complications of AMI, such as interventricular septal perforation, free wall rupture, and tend # on rupture, could be easily and promptly be diagnosed by 2DE. 3) 2DE was able to give information about the extent and the degree of the valvular lesions impaired by SBE, which was necessary for surgical treatment. 4) Myocarditis brought about myocardial inflammatory edema and asynergy, we could follow up serial changes throughout by 2DE. Thus, it was concluded that 2DE can play an important role for clinical diagnosis of acute cardiovascular diseases, because the method can be performed easily and noninvasively, and can provide valuable information which cannot be obtained by the other existing methods.

    For assessment of left ventricular (LV) function, two methods are described. The one for detection of regional wall motion abnormality (RWMA), left anterior oblique (LAO) and left posterior oblique (LPO) view gated pool images (GPI) were acquired using red blood cells labeled in vivo with 30 mCi Tc-99m. Due to the necessity of a statistical high quality GPI in this study, a scintillation camera with high sensitivity parallel hole collimator masked by Pb plate of aperture 20 cmφ was used for acquiring data in high count rate and to avoid piling up of the scintillation pulse. In an area of only 17×17 cm, the LV image data was stored in 64×64 matrix of a computer system at 32 frames per cardiac cycle. Fourier analysis was applied to the GPI. The result was the ability of detecting the anterior WMA in LAO view was more useful than in LPO view but the posterior WMA in LPO view was more useful than in LAO view. In a case of a two vessel disease, LAO and LPO view demonstrated the anterior and posterior WMA clearly. In the other method, to obtain an image synchronized to both respiratory and ECG during exercise, a conjunctive gate method was developed. The obtained images were clear without any blur. To evaluate LV ejection fraction corrected for respiratory movement, using only respiratory synchronized images, region of interests (ROIs) were selected in LV image at every respiratory phase. Corrected LV time activity curve was derived from the ROIs. The result was the LVEF without correction was underestimated and the LV volume curve was distorted.

    By means of RI angiocardiography, left to right shunt ratio and left ventricular ejection fraction (LVEF) were obtained in 188 children aged between 4 days and 18 years with suspected congenital heart disease. Scintillation camera (Toshiba GCA-70A) connected with computer system (Varian, Varicam II 64 kW) was utilized for this study. The majority of our examinations was done by bolus injection of 5-20 mCi/0.2-0.6 ml of Tc-99m-HSA. Regarding left to right shunt ratio in 55 children with left to right shunt, there was sufficient correlation (R=0.825) between the value obtained with gamma-function method and that from cardiac catheterization. Therefore, RI method was considered to be a choice of method as a less invasive screening type examination to obtain left to right shunt ratio. Regarding LVEF, there was insufficient correlation (R=0.625) between the value obtained with ECG gated cardiac pool image and that from M-mode echocardiographs in 76 children. However RI study can be performed with pharmacological stress and/or excercise stress because appeared to be beneficial for cardiac function test especially in children following an open heart surgery for congenital heart disease.

    The Kurt Rossmann Laboratories for Radiologic Image Research have conducted the basic studies in the area of optical imaging properties of radiographic systems, radiographic mottle, X-ray spectral analysis and computer simulations during the last two decades. In this article we have discussed our recent research on the absolute speeds and absorbed-energy constants of screen-film systems. Absolute speeds (mR^<-1>) of 27 screen-film systems were determined accurately and precisely from ten independent measurements over a six month period at several beam qualities that included both scatter and scatter-free conditions. The absorbed X-ray energies in the screens that yielded a net film density of 1.0 were obtained by means of Monte Carlo calculations and a semianalytical method. The standard deviations of the calculated absorbed X-ray energies at different beam qualities were less than 10% for all of the screen-film systems studied. Therefore, the absorbed X-ray energy that produces a given film density for these systems can be regarded as constant at the beam qualities used. Quantum absorption and fractional energy absorption of the screens were also calculated. The predicted wiener spectral values based on the number of photons detected were compared with the measured wiener spectral values of the screen-film systems.
