Abstract

a presente invenção revela um dispositivo de exame de formação de imagem de retrodifusão portátil e um método de formação de imagem. o dispositivo compreende: um alojamento de dispositivo (1), uma fonte de raio x (2), um mecanismo de modulação rotacional (3), um detector de raios (4), um sensor de movimento (5) e um controlador (6). a fonte de raio x (2), o mecanismo de modulação rotacional (3), o detector de raios (4) e o sensor de movimento (5) estão todos dispostos de maneira fixa dentro do alojamento de dispositivo (1). o detector de raios (4) é usado para receber dados de sinal de difusão da superfície de um objeto examinado para formar uma imagem bidimensional. o sensor de movimento (5) é usado para coletar, em um processo de varredura, uma trajetória de movimento espacial tridimensional e um ângulo de varredura do dispositivo. o controlador (6) é usado para combinar múltiplas imagens bidimensionais recebidas pelo detector de raios (4) com a trajetória de movimento espacial tridimensional e o ângulo de varredura para fornecer uma imagem tridimensional da superfície do objeto examinado. portanto, a modalidade implementa um efeito mais desejável de varredura e de formação de imagem para um objeto examinado que tem uma superfície curvada ou múltiplas superfícies irregulares.
