Description
A short description is given of earlier forms of the gamma-ray camera. The principle of operation of the scintillation camera is reviewed. Here the locations of scintillations occurring in a flat thallium-activated sodium iodide crystal are determined from the amount of light picked up by a number of phototubes simultaneously viewing the crystal. The signals from the phototubes are fed to a deflection computor circuit which reproduces the scintillations on a cathode-ray tube screen. There they are photographed by a conventional scope camera. Examples are shown of the resolution now obtained as shown by test phantoms. A discussion is presented of the camera's use in visualizing the thyroid in clinical practice. (author)
Abstract (French)
Les auteurs donnent une breve description des gammametres photographiques employes anterieurement. Ils rappellent le principe du fonctionnement du scintillometre photographique. Cet appareil permet de localiser des scintillations emises par un cristal plat d'iodure de sodium active au thallium d'apres le flux lumineux capte par plusieurs cellules photoelectrique s placees devant le cristal. Des cellules photoelectriques, les signaux sont transmis a un circuit de comptage a deviation qui reproduit les scintillations sur l'ecran d'un tube a rayons cathodiques. Elles sont ensuite photographiees a l'aide d'un appareil ordinaire. Au moyen de , les auteurs donnent des exemples du pouvoir de resolution qu'il est possible d'obtenir maintenant. Ils etudient l'utilisation du dispositif pour la representation visuelle de la thyroide dans la pratique clinique. (author)Abstract (Spanish)
El trabajo ofrece una breve description de las camaras de rayos gamma utilizadas anteriormente. Se pasa revista al principio de funcionamiento de la camara de centelleo. Ese aparato permite localizar los destellos emitidos por un cristal piano de yoduro de sodio activado por talio, en funcion del flujo luminoso captado por cierto numero de celulas fotoelectricas enfocadas simultaneamente sobre el cristal. Las senales procedentes de las celulas fotoelectricas se transmiten a un circuito contador de desviacion que reproduce los destellos sobre la pantalla de un tubo de rayos catodicos. Seguidamente esos destellos se fotografian mediante una camara normal. Los autores presentan ejemplos del poder de resolucion ya conseguido, conforme lo revelan ensayos realizados con modelos o ''maniquis'' y estudian el empleo de la camara para la representacion visual de la tiroides en la practica clinica.

Daetsya kratkoe opisanie sushchestvovavshi kh ranee gammaustanovok. Rassmatrivaetsya printsip dejstviya stsintillyatsionno j kamery. V dannom sluchae lokalizatsiya stsintillyatsij, proiskhodyashchikh v ploskom aktivirovannom talliem kristalle jodistogo natriya, opredelyaetsya iz kolichestva sveta, popadayushchego na ryad foto-ehlementov, odnovremenno obsledyvayushchi kh ehtot kristall. Signaly fotoehlementov peredayutsya na otklonyayushchij schetnyj koitur, kotoryj vosproizvodit stsintillyatsii na ehkrane katodnoj trubki. Zatem oni fotografiruyuts ya obyknovennym fotoapparatom. Privodyatsya primery dostatochnoj v nastoyashchee vremya razreshayushchej sposobnosti pri ispytanii fantomov. Obsuzhdaetsya vopros o primenenii upomyanutoj kamery dlya nablyudeniya za shchitovidnoj zhelezoj pri klinicheskikh issledovaniyakh. (author)Additional details
