[ES] La invención describe un sistema de cámara compton de rayos gamma con medida de tiempo de vuelo que comprende: - una pluralidad de módulos detectores (3), cada uno de ellos comprende un material sensible a la radiación gamma y dispuestos en capas formadas por uno o más módulos detectores, dichas capas están dispuestas de modo que interfieren un rayo gamma entrante para absorberlo parcial o completamente después de una o más interacciones compton, y están espacialmente separadas para permitir determinar el orden temporal de cada interacción del rayo gamma dentro del sistema de la cámara, - electrónica de lectura y sistema de adquisición de datos en el que las señales procedentes de los módulos detectores serán leídas, digitalizadas y enviadas a una unidad de procesado, y capaz de obtener la posición 3D, la energía y el orden secuencial temporal de las interacciones individuales - compton fotoeléctricas - producidas por un único rayo gamma incidente, lo que permite la determinación de la secuencia de tiempo completa de todas las interacciones de rayos gamma dentro del volumen de detección de rayos gamma.
[EN] The invention relates to a Compton gamma-ray camera system with time-of-flight measurement, which comprises: a plurality of detector modules (3), which each comprise a material sensitive to gamma radiation and are disposed in layers formed by one or more detector modules, the layers being disposed such that they interfere with an entering gamma ray to partially or completely absorb same following one or more Compton interactions, and being spatially separated to allow the determination of the temporal order of each gamma-ray interaction within the camera system; and reading electronics and a data acquisition system in which signals from the detector modules are read, digitalised and transmitted to a processing unit. The camera system is capable of obtaining the 3D position, energy and temporal sequential order of individual interactions - Compton and photoelectrical - produced by a single incident gamma ray, allowing the determination of the complete time sequence of all the gamma ray interactions in a gamma ray detection volume.
