PURPOSE:To enable exact data acquisition even with the change of heart beat period by detecting each of a living body image data and heart movement, and preserving the heart movement data at the time of image data detection together with the elapsed time information from the reference time phase. CONSTITUTION:A living body image data from a cancer camera is temporarily stored in either of input buffers 2 or 3 by way of a switching circuit 1. Out of the electrocardiowave signals of an electrocardiograph an R wave is detected 5 and for every detection signal the circuit 1 is switched by turns. And the switching circuit 4 on the output side of the buffers 2 and 3 is switched by turns in the opposite phase to it. By this detection signal, the elapsed time information from the reference time phase is also added 10 to the image data simultaneously. These are read in this manner from the buffer where no data is stored and the image data are distributed to image memories 81 to 8n based on the elapsed time information by a distributing circuit 6 and also stored in a memory device 9. Thus, the quality and measurement accuracy of the restructured images are raised by the data synchronized with the heart movement. |
