AbstractAbstract
[en] This invention concerns a process and apparatus for examination by penetrating radiation, particularly by tomography. Specifically, the invention refers to the 'tacography' or computer assisted axial tomography machines and, in particular, the machines working by translational and rotational displacement. Such a translational and rotational scanner is designed so that the radiation source and detectors move by translation on a carriage at non constant speed. Data samples are taken, for unit distances in space and not during unit times

La presente invention concerne un procede et un appareil d'examen a l'aide de radiations penetrantes, notamment par tomographie. Plus precisement, l'invention concerne les appareils de tacographie ou tomographie axiale assistee par ordinateur, et plus precisement les appareils fonctionnant par deplacement de translation et de rotation. Un tel appareil a balayage par translation et rotation est concu de telle sorte que la source de radiations et les detecteurs se deplacent en translation sur un chariot a vitesse non constante. Des echantillons de donnees sont preleves, pour des distances elementaires dans l'espace et non pendant des temps elementairesOriginal Title

AbstractAbstract
[en] A radiographic apparatus for investigating a cross-sectional slice of a body is described, the apparatus including: a source of a fan-shaped distribution of penetrating radiation, directed towards the slice; scanning means for orbiting the origin of the radiation about the slice so as to direct radiation towards the slice from a plurality of directions; detector means comprising a plurality of detector devices which face the slice and are arranged in a ring, and means for nutating the detector ring in synchronism with the motion of the origin of the radiation

AbstractAbstract
[en] Colour CT should not be routinely used but be reserved for certain cases presenting difficulties of interpretation and for certain types of images. However, side by side viewing in monochrome and colour is of considerable diagnostic interest. (orig./AJ)

Farbaufnahmen bei CT bereiten Schwierigkeiten bei der Interpretation und bei bestimmten Bildarten und sollten daher nicht fuer Routineuntersuchungen verwendet werden. Von grossem diagnostischem Interesse ist jedoch das gleichzeitige Betrachten von Schwarzweiss- und Farbbildern. (orig./AJ)Primary Subject

AbstractAbstract
[en] Awesome recent accomplishments in CT scanning will pale by comparison to some of the sophisticated advances that are now on the horizon. Future advances will occur in dynamic scanning, enhanced resolution, new contrast media development, and image manipulation

AbstractAbstract
[en] Many tumors in the brain and in other tissues can be delineated precisely in images obtained with a CT scanner. After the scan is obtained the patient is taken to another room for radiation therapy and is positioned in the beam with the aid of external markers, simulators or stereotactic devices. This procedure is time consuming and subject to error when precise localization of the beam is desired. The CT scanner itself, with the addition of the collimator, is capable of delivering radiation therapy with great precision without the need for external markers. The patient can be scanned and treated on the same table, the isocenter of the beam can be placed precisely in the center of the lesion, the beam can be restricted to just those planes in which the lesion appears, several arcs can be obtained by simply tilting the gantry, and the position of the patient in the beam can be monitored continuously during therapy. The authors describe the properties of the CTX, the CT scanner modified for therapy. (author). 6 refs.; 6 figs

AbstractAbstract
[en] A total of 82 patients who underwent spinal computed tomographic scan, in an 8-month period at the King Khalid University Hospital, Riyadh, Saudi Arabia, were analyzed for age, sex, the presence/absence, site, and type of ossification of the ligamentum flavum (OLF) as well as associated diseases. The OLF was radiographically present (bilaterally or unilaterally) as linear (74.5%) or nodular types (25.5%). The linear type was especially seen at the inner aspects of the ligamentum flavum. OLF was present in 35.4% of patients, and was seen at single and multiple levels in 51% and 41% of them, respectively. OLF was identified in a total of 47 levels in the study group and was associated with other disease in the spine in 38 (81%) of these levels. In none of the patients was OLF the cause of myelopathy. The incidence of OLF and its pathogenesis and significance are discussed. This paper is the first report of OLF from the Middle East. OLF in this part of the world is usually asymptomatic

AbstractAbstract
[en] During ECG-controlled cardio-computer tomography, only certain defined phases of the cardiac cycle are used for computing the image. Consequently several cycles are necessary in order to obtain the required projection. ECG-controlled cardio-computer tomography produces findings regarding dys- or akinetic portions of the myocardium which are in good agreement with the laevo-cardiogram. The septum, apex and antero-lateral wall are demonstrated most easily, since their movement lies within the appropriate plane. Demonstration of the anterior and posterior walls is more difficult, since their movement is angled to the computer tomographic plane. (orig.)

Bei der EKG-gesteuerten Kardiocomputertomographie werden nur die einer bestimmten Herzphase zugehoerigen Messwerte fuer die Bildberechnung beruecksichtigt. Daher sind zur Erlangung der erforderlichen Anzahl von Projektionen mehrere Umlaeufe erforderlich. Mit der EKG-gesteuerten Kardiocomputertomographie ist der Nachweis dys- oder akinetischer Herzwandabschnitte in guter Uebereinstimmung mit den Befunden der Laevokardiographie moeglich. Am guenstigsten sind die Abbildungsbedingungen fuer das Septum, die Spitzenregion und die Anterolateralwand, deren Bewegungen innerhalb der computertomographischen Schichtebene stattfinden. Die Beurteilung der basisnahen Vorder- und Hinterwand ist schwieriger, da deren Bewegungen schraeg zur computertomographischen Schichtebene verlaufen. (orig.)Original Title
