PROBLEM TO BE SOLVED: To form further fine picture by scanning an object while projecting a radiation against the object, sensing the radiation with plural sensors, processing the outputs of the sensors and forming the sample matrix of a picture. SOLUTION: Electric signals from each of the detectors of an object scanner 2 or the sensors are transmitted to and stored in the projection data memory of an image receiving device 4. The stored signals are supplied to an image processor 6 to be processed the display of radiation attenuation from the respective sensor. A calculating device 14 in the image processor 6 calculates sample matrixes from the signals supplied from the sensors or the detectors. A processing means supplies the sample matrix of an image, and this is stored in an image matrix storing device 8. The sample of each detector represents attenuation data collected along one of the projecting routes from a radiation source. An image matrix storing element is connected to a video monitor 12 and a printer 10 to reproduce a visible image. |
