PURPOSE:To enable utilization of a space inside an image area by a method wherein data are distributed to peripheral addresses and added as to an address saturated with local concentration of detection of a radioactive material (RI) at the time when image data on an RI image are collected. CONSTITUTION:Position data obtained from detection pass through an address selecting switch 1 and are inputted to an address bus of an image memory 2 and an address of the memory 2 is specified. Data called out for the specified address are inputted to an add one (ADD1) circuit 3 from a data bus and the data to which +1 is added in this circuit 3 are written in the specified address as they are, when the address is not in a state of overflow. In the case when the address is in the state of overflow, a control circuit 4 changes over the switch 1 and a random number addition circuit 5. Thereby a random number is added to the original address data and the same add one operation is executed. Thus, utilization of a space inside an image area relevant to the data is enabled. |
