Abstract

otimização do padrão de disparo da fonte para sistemas de varredura por raios x. o presente pedido divulga um sistema de tomografia computadorizada tendo fontes de raios x não rotativas que são programadas para otimizar o padrão de disparo de fonte. em uma modalidade, o sistema tc é um scanner de tc de feixe cônico rápido que utiliza um anel fixo de múltiplas fontes e anéis fixos de detectores em um formato geométrico desencontrado. deve ser observado que o padrão de disparo de fonte é efetuado por um controlador que implementa métodos para determinar um padrão de disparo de fonte que são adaptados a geometrias em que as fontes de raios x e dos detectores são desencontradas.
