Abstract
SE UTILIZA UNA SONDA DE RADIACION GAMMA MANUAL (12) PARA LOCALIZAR CONCENTRACIONES DE RADIACION EN TEJIDO ANIMAL JUNTO CON UNA FUNCION DE CONTROL QUE PROPORCIONA UNA SALIDA MEJORADA DE AUDIO, PARTICULARMENTE APROPIADA PARA PRESERVAR AL USUARIO EN CUANTO A LA POSICION DE LA FUENTE. LA SONDA (12) ESTA COLOCADA EN UNA POSICION EN EL CUERPO DEL ANIMAL QUE REPRESENTA LA RADIACION DE FONDO Y DE ELLO SE DESARROLLA UNA TASA DE COMPUTO BAJO DE AMORTIGUACION. LA TASA DE CONTADOR DE BAJA AMORTIGUACION SE MULTIPLICA POR UN FACTOR DE INTERVALO PARA DESARROLLAR UNA TASA DE COMPUTO ALTO DE AMORTIGUACION Y SE DESARROLLAN FRECUENCIAS A PARTIR DE UNA TABLA DE FRECUENCIA DE BLOQUEO DESDE LA MAS BAJA A LA MAS ALTA DE ACUERDO CON LAS TASAS DE COMPUTO DE ALTA Y BAJA AMORTIGUACION. LA LIMITACION DE TASA DE GIRO DE LAS TASAS DE COMPUTOS SE PROPORCIONA MEDIANTE EL DESARROLLO DE UN VALOR DELTA DE AMORTIGUACION QUE REPRESENTA LA DIFERENCIA ENTRE LAS TASAS DE COMPUTOS ALTO Y BAJO DE AMORTIGUACION DIVIDIDAS POR UN ELEMENTO DE TIEMPO. LA SELECCION DE FRECUENCIA DE SALIDA AUDIO A PARTIR DE LA TABLA DE FRECUENCIAS ESTA LIMITADA POR EL VALOR DEL VALOR DELTA DE AMORTIGUACION. SE REALIZA UN CONTROL CONTINUO DE LOS COMPUTOS DE RADIACION RECIBIDA PARA DESARROLLAR LOS VALORES DE TASA DE COMPUTO UTILIZADOS POR EL SISTEMA.
