Abstract

APARATO PARA LA DETERMINACION DE CONTENIDO DE MINERAL OSOSO POR ABSORCION PARCIAL DE RADIACIONES IONIZANTES POR UNA FUENTE CONSTITUIDA PREFERENTEMENTE DE DOS ELEMENTOS. COMPRENDE UN CARRO MOVIL (22) SOBRE CORREDERAS Y DOS BRAZOS (23,24) PORTADORES DEL BLOQUE EMISOR (27) DE HAZ RADIOACTIVO Y DEL BLOQUE RECEPTOR (28) Y ARTICULADOS DE TAL MANERA QUE LA INCIDENCIA DEL HAZ PUEDE SER INDIFERENTEMENTE HORIZONTAL O VERTICAL. EL BLOQUE RECEPTOR (28) ESTA PROVISTO DE UNA PLURALIDAD DE CAPTADORES (92,93) QUE PERMITEN LA REALIZACION DE UNA IMAGEN EN DOS DIMENSIONES POR LA SIMPLE TRASLACION DEL CARRO (22). EL APARATO ES PARTICULARMENTE CONCEBIDO PARA EL EXAMEN DE LA DESMINERALIZACION DE LA COLUMNA VERTEBRAL CON EL PACIENTE TENDIDO SOBRE UNA MESA (29).
