Image forming apparatus

A medical imaging apparatus for imaging a subject using gamma rays and rays emitted from the subject, the apparatus comprising: separation means for separating gamma rays and rays emitted from the subject into a gamma ray channel comprising gamma rays and a ray channel comprising rays; a first sensor arrangement arranged to receive and detect gamma rays from the gamma ray channel and to generate a first signal for forming a first image of the subject; a second sensor device arranged to receive and detect light from the light channel and to generate a second signal for forming a second image of the subject; wherein the first sensor device and the second sensor device are arranged to receive gamma rays and light rays, respectively, which propagate from the subject on substantially coincident paths. 一种用于使用从受试者发出的伽马射线和光线对受试者进行成像的医学成像设备，该设备包括：用于将从受试者发出的伽马射线和光线分离到包括伽马射线的伽马射线通道和包括光线的光线通道中的分离装置；被布置成接收和检测来自伽马射线通道的伽马射线并生成用于形成受试者的第一图像的第一信号的第一传感器装置；被布置成接收和检测来自光线通道的光线并生成用于形成受试者的第二图像的第二信号的第二传感器装置；其中，第一传感器装置和第二传感器装置被布置成分别接收
