Abstract

SE PERFECCIONAN LOS MOVIMIENTOS DE UNA GAMMA CAMARA, EN PARTICULAR DE UNA GAMMA CAMARA DOTADA DE DOS CABEZAS (8,9) DETECTORAS SOPORTANDO A CADA UNA DE ESTAS CABEZAS DETECTORAS POR UN ESTRIBO (14) DOTADO DE DOS FLANCOS (12, 13). EN EL INTERIOR DE CADA UNO DE LOS FLANCOS SE PUEDE DESLIZAR UN SOPORTE QUE MANTIENE UN EJE (10,11) DE ANGULACION Y DE SUJECION DE LA CABEZA DETECTORA. CADA CABEZA DETECTORA PUEDE ASI SER DESPLAZADA EN TRASLACION (17) INDEPENDIENTEMENTE CUANDO LOS DOS SOPORTES SE DESPLAZAN JUNTOS Y EN EL MISMO SENTIDO EN LOS FLANCOS. PUEDE POR OTRA PARTE ACEPTAR UN MOVIMIENTO DE ANGULACION (18, 19) CUANDO ESTA GIRADA SOBRE SI MISMA ALREDEDOR DE ESTOS EJES. SE MUESTRA QUE ESTE DISPOSITIVO MEJORA LA ERGONOMIA DE UTILIZACION Y QUE POR OTRA PARTE PERMITE REALIZAR IMAGENES DE MEJOR CALIDAD.
