Abstract

Cámara gamma portátil, que comprende: un cuerpo (2) de contención; - una estructura (3) de medición que comprende una estructura de centelleo alojada en el interior del cuerpo (2) de contención y destinada a recibir radiación; - un colimador (4) hecho de un material de alto número atómico, asociado a la estructura (3) de medición para absorber una radiación lateral dirigida hacia la estructura (3) de medición y que tiene un ángulo de incidencia mayor que un valor predeterminado; - una pantalla (5), colocada sobre el cuerpo (2) de contención; - una unidad (6) de control electrónico que opera entre la estructura (3) de medición y la pantalla (5) para generar en la pantalla (5) imágenes que representan la radiación interceptada por la estructura (3) de medición; caracterizada porque la unidad (6) de control electrónico comprende: - al menos un convertidor (7) optoelectrónico; - un sistema electrónico diseñado para leer, amplificar e integrar señales de salida de al menos uno de los convertidores optoelectrónicos. - una red resistiva conectada al sistema electrónico y capaz de determinar el baricentro de carga y la energía asociada con la radiación que impacta la estructura de centelleo; - un sistema para la conversión analógica/digital y el muestreo de las señales que utilizan dispositivos PIC equipados con ADC/DAC, estando diseñado el sistema de conversión y muestreo para recibir de la red resistiva una señal que identifica el baricentro de carga y la energía asociada con la radiación que impacta la estructura de centelleo y está diseñada para integrar la señal para determinar la amplitud y generar una señal de salida respectiva; - un sistema de microcontrolador de tipo PIC o ARM, conectado al sistema de conversión y muestreo para recibir la señal de salida y convertirla en una imagen que se puede visualizar en la pantalla; en el que el sistema electrónico, la red resistiva, el sistema de conversión analógico/digital y el sistema de microcontrolador están situados secuencialmente entre el convertidor (7) optoelectrónico y la pantalla (5).
