Abstract

The scanner described was built to explore potential advantages of modifying the motion of the radiation detector over the patient. In the study of a round organ, such as the liver, a cylindrical scanning motion is used to expose more of the organ to survey. Another modification is section scanning which permits the separation of images of radioactive structures according to specific planes in body depth. This mode of scanning can be of particular use when images of body structures overlap in the recording and are confusing. During scanning the patient is supported on a cantilever platform between two opposed scintillation detectors mounted at the extremities of a yoke. The yoke is powered to provide three motions of the detectors about the patient: longitudinal, transverse, and rotary. Particular attention has been paid to the precise control of detector position and speed by incorporating servo-mechanical control mechanisms. The recording system includes: (1) Non-destructive data storage on punched paper tape; (2) provision for rapid regeneration of scanning images on a cathode-ray oscilloscope-, and (3) facility for electronic operations on the image signal. Examples of the clinical applications of this instrument are described, with particular emphasis on cylindrical scanning of the liver and  More>>

(author) [French] Le dispositif decrit dans le memoire a ete construit en vue d'etudier les avantages qui pourraient resulter de la modification du deplacement du detecteur de rayonnement au-dessus du patient. Dans l'etude d'un organe a peu pres rond tel que le foie, on procede a l'exploration par un mouvement en spirale afin d'examiner une plus grande portion de l'organe. On peut egalement faire une exploration par 'tranches' , qui permet de separer les images des structures radioactives dans des plans determines en profondeur. Ce mode d'exploration peut se reveler particulierement utile lorsque les images des diverses structures se superposent sur le scintigramme, qui est alors difficile a interpreter. Au cours de l'exploration, le patient est installe sur un lit cantilever entre deux detecteurs a scintillation montes aux extremites d'un.support qui se deplace de maniere a permettre le mouvement des detecteurs en trois sens: longitudinal, transversal et rotatoire. On aveille tout particulierement a assurer un controle precis de la position et de la vitesse des detecteurs par l 'incorporation de servo-mecanismes. Le systeme d'enregistrement comprend: a) un stockage permanent des donnees sur bandes de papier perfore; b) un moyen de reproduction rapide des images scintigraphiques sur un oscilloscope a rayons cathodiques; c) un dispositif electronique d'exploitation des signaux. L'auteur donne des exemples des applications cliniques de cet appareil, notamment de l'exploration en spirale du foie et de l'exploration dans plusieurs plans du cerveau. (author) [Spanish] El aparato descrito en la memoria se construyo para estudiar las ventajas que puede ofrecer el empleo de un detector de radiaciones que se desplace sobre el enfermo de manera distinta de la habitual. Al estudiar un organo aproximadamente redondo, como el higado, el aparato es animado de un movimiento cilindrico a fin de poder explorar una parte mayor del organo. Otra modificacion consiste en la exploracion por secciones, que permite separar imagenes de estructuras radiativas en planos situados a diversas profundidades del organismo. Este procedimiento tiene particular interes cuando las imagenes de las diversas estructuras corporales se superponen en el registro dando resultados dificiles de interpretar. Durante la exploracion, el paciente se encuentra sobre una camilla sujeta por uno de sus extremos y situada entre dos detectores de centelleo montados en las extremidades de una pieza en forma de yugo capaz de desplazarse'en direccion longitudinal y transversal y de describir un movimiento giratorio. Se ha prestado particular atencion a la posibilidad de regular exactamente la posicion y la velocidad del detector y, para ello, se han instalado servomecanismos de control. El sistema de registro comprende: a) almacenamiento no destructivo de datos sobre cinta de papel perforada, b) posibilidad de regenerar rapidamente las imagenes de exploracion en un osciloscopio de rayos catodicos y c) un dispositivo para analizar electronicamente las imagenes. En la memoria se describen algunos ejemplos de aplicaciones clinicas de este aparato y, en particular, la exploracion cilindrica del higado y la exploracion del cerebro por secciones.
