Abstract

a invenção se refere a um detector de radiação (100') e a um método para detectar radiação, particularmente para detectar raios x (x) em um aparelho de imageamento por tc (1000'). de acordo com uma modalidade preferencial, o detector de radiação (100') compreende um elemento de conversão (110) para converter a radiação incidente (x) em sinais elétricos que são lidos e processados por um circuito de leitura (120). um dispositivo de aquecimento que compreende a fonte de calor (135') de um elemento peltier é fornecido, com o qual o elemento de conversão (110) pode ser aquecido de maneira controlável, de modo a reduzir os efeitos negativos, por exemplo, da polarização, sobre a precisão de imagem, em que o dissipador de calor (137') do elemento peltier é orientado em direção ao circuito de leitura.
